CAUTION

ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL
INJURY OR DEATH

This symbol refers to a hazard or
unsafe practice, which if not avoided,
might result in minor or moderate injury
or product or property damage.



The engine exhaust from this product
! DANGER contains chemicals known to the state
of California to cause Cancer, Birth
Defects or other reproductive harm.




Fuels, electrical equipment batteries, exhaust gases and moving parts
present potential hazards that could result in severe personal injury.
Take care in following these recommended procedures.



FUELS AND FUMES ARE FLAMMABLE:
Fire, explosion and severe personal injury can result from improper
practices. When transporting generator set, always close the fuel shut
off valve located beneath the bottom of the fuel tank.







DO NOT fill fuel tanks with the engine running. Fuel contact
with the engine or exhaust is a potential fire hazard. Let the
engine cool down before removing gas cap.
DO NOT SMOKE OR ALLOW AN OPEN FLAME near the
generator set or fuel tank.
DO NOT store or transport the generator wet without first
removing the fuel from the tank.
DO NOT SMOKE while servicing batteries. Lead acid
batteries emit a highly explosive hydrogen gas that can be
ignited by electrical arcing or by smoking.
DO NOT mix lubricating oil with gasoline.
When refueling always wait until the unit has cooled down
before opening/removing the fuel cap.







Disconnect starting battery before removing protective
shields or touching electrical equipment.
Use rubber
insulated mats placed on dry wood platforms over floors that
are metal or concrete when around electrical equipment. Do
not wear wet damp clothing (particularly wet shoes) or allow
skin surfaces to be damp when handling electrical
equipment.
Use extreme caution when working on electrical
components. High voltages can cause injury or death. DO
NOT tamper with interlocks.
Follow all applicable state and local electrical codes. Have
all electrical installations performed by a qualified licensed
electrician. Tag open switches to avoid accidental closure.
DO NOT CONNECT GENERATOR SET DIRECTLY TO
ANY BUILDING ELECTRICAL SYSTEM.
Hazardous
voltages can flow from the generator set into the utility line.
This creates a potential for electrocution or property
damage. Connect only through an approved device and
after building main switch is open. The National Electrical
Code and Canadian Standards Association require an
approved switch device between the generator set and the
utility power. Consult a licensed electrician in regard to
emergency power use.
DO NOT use the generator set in rain, snow, sleet or wet
ground conditions.

GENERAL SAFETY PRECAUTIONS




EXHAUST GASES ARE DEADLY


Before performing any maintenance on the generator set,
disconnect the spark plug wire (and the starting battery
negative cable on electric start models) to prevent accidental
starting.
Keep hands away from moving parts
Do not wear loose clothing or jewelry while servicing any
part of the generator set. Loose clothing and jewelry can
become caught in moving parts. Jewelry can short out
electrical contacts and cause shock or burning.
Make sure that fasteners on the generator set are secure.
Tighten supports and clamps, keep guards in position over
fans, drive belts and heat shields, etc.
If adjustment must be made while the generator set is
running, use extreme caution around hot manifolds and
moving parts, etc.

Engine exhaust contains CARBON MONOXIDE, a
dangerous, invisible gas that you cannot smell that is
potentially lethal. Avoid carbon monoxide inhalation by
operating the generator set outdoors where exhaust gases
can be discharged directly into the open air. Use a batterypowered carbon monoxide detector when running generator.
Do not operate the generator set in any type of enclosure
that could allow exhaust gases to accumulate such as inside
garages, crawl spaces or inside vehicles of any type. Using
a fan and opening doors or windows does NOT provide
enough fresh air. Direct exhaust gas away from areas
where people are gathered and away from building or
enclosures. If you start to feel sick, dizzy or weak while
using generator, shut it off and get fresh air immediately.
See a doctor. You may have carbon monoxide poisoning.
Do not operate the generator set in an enclosed
compartment such as found in recreational vehicles or
enclosed trucks (even with the tail gate open). All warranties
are voided if the unit is operated in an enclosed area.
Operate only in well-ventilated area.

Have a fire extinguisher nearby. Maintain extinguisher
properly and become familiar with is use. Extinguisher rated
ABC by the NFPS is appropriate for all applications. Consult
the local fire department for the correct type of extinguisher
for various applications.
Benzene and lead, found in some gasoline, have been
identified by some state and federal agencies as causing
cancer or reproductive toxicity. When checking, draining or
adding gasoline, take care not to ingest, breathe the fumes,
or contact gasoline.
Used engine oils have been identified by some state or
federal agencies as causing cancer or reproductive toxicity.
When checking or changing engine oil, take care not to
ingest, breathe the fumes or contact used oil.
Remove all unnecessary grease and oil from the unit.
Accumulated grease and oil can cause overheating and
engine damage and present a potential fire hazard.
DO NOT store anything on the generator set such as oilcans, oily rages, chains, wooden blocks etc. A fire could
result or operation could be adversely affected. Keep the
generator set clean and dry at all times.
DO NOT work on this equipment when mentally or physically
fatigued, or after consuming alcohol or any drugs.
Never remove radiator cap or radiator reservoir cap while
engine is hot or running. Severe burns or injury can occur by
escaping steam or hot engine coolant.

PRESTART OPERATION

BREAK IN & CONTINUOUS OPERATION/LOAD
APPLICATION FOR DIESELS ONLY

Before starting the engine, read the engine manual for the proper type
oil type and volume and fuel type.

After the engine operates properly, it is strongly recommended to
ALWAYS have an electrical load of at LEAST 25% of the nameplate
rating on the generator when operating the unit. Operating the engine
without an electrical load for prolonged periods of time (one hour or
more) will eventually cause damage to the diesel engine (sometimes
called wet stacking which is NOT covered by the engine
manufacturer’s warranty) or damage to the rings, fuel oil entering the
lubricating oil and excessive vibration. Breaking in the diesel engine
can require 5 to 10 hours of operation. It is extremely important to
have electrical loads of at least 25% to 50% of the rated capacity of the
generator’s nameplate rating to have the valves properly seat. Be sure
to change the oil and oil filter after several hours of initial operation. All
oil and fuel filters should be changed every 250 hours of operation and
air filters as often as necessary depending on the environment. Dirty
filters WILL cause erratic operation, dark exhaust fumes and erratic
voltage from the generator. Consult the engine owner’s manual for
complete engine operation. If the diesel engine does not stop when the
start/stop switch is turned off, the oil in the engine sump has been over
filled and the engine is using over pressurized sump oil as fuel. To
stop the engine with this condition you must block the air intake flow
which will stop the engine. Eventually the engine will consume the
excess sump oil and stop on it's own but this could take some time. If
this situation has occurred, you must check the air filter as pressurized
oil has gone through the engine breather and saturated the air filter.
The air filter MUST be replaced before restarting the engine.

FUEL AND FILLING FUEL
On all gasoline powered models use unleaded gasoline of at least 87
octane rating. On all diesel powered units fill with diesel fuel No2
(DF2) in normal ambient temperatures or NO1 (DF1) in cold weather.
JP5 or JP8 turbine fuel may be used on diesel powered units only with
slight engine de-rations. The fuel shut off valve is located on the
bottom of the fuel tank. Be sure that the valve is turned counter
clockwise (the open position) to permit the flow of fuel from the tank.

OIL FILLING INSTRUCTIONS
Fill the oil sump or to the full mark on the dipstick (if applicable).
(Figure 1) Pour slowly to avoid air bubbles. To avoid engine damage
always check for full oil level before starting engine. Crankcase
pressure can blow hot engine oil out the fill tube causing severe burns,
always stop the engine before removing the oil cap. Do not overfill the
oil level on 13, 16, 18, 20, 23, 25 and 31 HP gasoline engines and all
diesel engines, as damage will occur. Engine damage due to low oil
level is NOT covered by the engine manufacturer’s warranty. For
gasoline engine refill with API Class SG or SH oil (also SG/CD,
SG/CE, SH/CD or SH/CE) having an SAE viscosity grade appropriate
for the temperatures as indicated below. For diesel engines, see the
engine manual for the proper oil selection.

CAUTION

This generator set should only be operated by a
responsible adult.

To start the engine:
1. Disconnect all loads to start the engine.
2. Fully open the fuel valve if the engine is so equipped. The
valve is located under the unit-mounted fuel tank of the
engine or under the fuel tank on all LR units.
3. Adjust the carburetor choke as necessary for temperature
conditions. Cold starting requires a full choke. L/P and N/G
fueled engines do not require a choke. There is no choke on
all diesel powered generator sets.
4. The engine may be equipped with a rope recoil starter or
electric starter.
Start the engine by referring to the
paragraph in the engine manual for the applicable starter.

15W-40

OIL FILLING FOR DIESELS
Fill the oil sump with lubricating oil with 15W30 multigrade for warm
weather and 5W30 for cold weather. Oil capacity for the LR50/60EL
models with the 15LD400 engine is 1.26 quarts and for the LR130EL
with the 25LD425 engine is 1.9 quarts (without filter). Check the
dipstick each time fuel is added to maintain the proper levels of
lubricating oil. IMPORTANT Do not overfill with oil or damage will
occur to the engine.
Maintain the oil level within the
minimum/maximum lines of the dipstick. Engines overfilled MUST be
drained until the oil level is at the above noted levels.

STARTING ELECTRIC START DIESELS WITHOUT A
BATTERY

All contractor diesel welder/generators and three phase and some
medium duty units are equipped with either low oil volume or low oil
pressure shut down systems. Insufficient oil volume or pressure will
cause the engine to stop. See engine manual for complete details.

The models LR50EL and LR60EL are electric start models with
auxiliary recoil starters. If a battery is not available, the red or black
lever near the fuel pump MUST be in the up position to start and to
stop the engine turn the red or black lever to the down position.
Without a battery, the key start/stop switch will NOT stop the engine
and you MUST use the red or black lever. When using the electric
start switch to start and stop the engine and a 12 volt battery is
installed, the red or black lever MUST be in the down position at all
times.

BREAK IN PROCEDURE

INITIAL STARTING OR UNIT RUN OUT OF FUEL ON
DIESELS ONLY

LOW OIL SHUT DOWN

Controlled break in with the proper grade of lubricating oil helps to
ensure satisfactory service from the generator set. During the first 2-3
hours of operation, do not apply heavy electrical loads to the
generator. Oil should be changed after the first 3 hours of operation.
The oil changes should then be scheduled at the recommended times
shown in the engine manual. Two cylinder air cooled diesel powered
units MUST be run with at least 25% load at all times or damage to the
engine may occur. Oil should be drained when the engine is still
slightly warm.

Air pockets in the fuel line will cause difficulty in engine starting and
normal operation when fueling the unit for the first time or the unit is
run out of fuel. It is strongly recommended to manually pump the
pump lever 20 plus times before starting to release the air pockets.
Models LR50EL and LR60EL have clear fuel filters and air pockets can
be visually observed. Even one air bubble will cause erratic engine
operation. ALL air pockets must be pumped out to operate properly.
The model LR130EL has a solid metal fuel filter and air pockets cannot
be observed in this model. Always avoid running a diesel out of fuel or
near the bottom of the fuel tank as air pockets may be induced causing
erratic operation of the engine. Once all diesels have been initially
started and the engine runs smoothly, there is no need to bleed out air
pockets in future starting of the unit.

For units operating on liquid propane L/P or natural gas N/G, see
addendum instruction sheets for proper installation and operation.

DUST, DIRT, RAIN AND SNOW

SPARK ARRESTER REQUIREMENTS

Operating the generator set in extreme dusty or dirty conditions will
seriously affect the life of the engine.
Keep the unit clean and do not allow snow, rain, dust or dirt to
accumulate on the unit. Remove all oil deposits and accumulated dirt.
When operating the unit, protect it from the elements. Do not use this
product in rain, snow or wet locations.

Some generator sets have either internal or external spark arresters.
Some units are not equipped with spark arresters.

FIGURE 1

If the generator set is used in a National Park,
any forest covered land, grass covered land, or
the state of California, a spark arrester MUST be
installed and in working order to comply with California Section 4442
and 4443. A USDA Forestry Department approved spark arrester kit is
offered as optional by the engine manufacturer. When installed, the
spark arrester must be firmly attached to the muffler and the screen
must be kept clean and unplugged for proper operation. Contact your
local engine manufacturer’s distributor for more information. Engine
company distributors are listed in the yellow pages under engines
gasoline or gasoline engines. Even with the spark arrester installed,
extreme care must still be used if the engine is operated in an area of
dry forest covered brush or dry grass, which could catch fire from the
engine heat or an accidental spark.

! DANGER

OIL DRAIN
PLUG

All generator sets must be externally grounded.
All generator sets are grounded internally to an
external ground on the frame. OSHA, the National Electrical Code and
most state and local codes require an additional external ground rod
pounded into the soil and securely connected to the external ground on
the generator set. Only three or four prong plugs must be used with
each receptacle on the unit. Use only 3 prong extension cords. It is
recommended to use #10 copper stranded wire from the generator to
the external ground rod. The ground rod and wire are not provided
with the generator set.

BATTERY

WET CONDITIONS

The customer must supply the starting battery. Battery cables and a
battery tray are installed on the generator set. All batteries must be 12
volts DC. For all gasoline models through and including LR150’s a
type U1 300 cold cranking amps battery is required (5.0” max width).
For the model series LR180 and all diesel models a type 24BCI, 26BCI
or 34/78 12 volt DC battery of at least 400 or more cold cranking amps
is required (6 7/8” max width).

Use extreme care to avoid a lethal shock hazard
if this unit is operating outdoors during periods of
visible moisture (rain or snow) or near standing
water. Service the air cleaner at least every 25 to 30 hours if operating
in extremely dusty or dirty conditions. Change the oil in the crankcase
at least every 50 hours of operations (see engine manual for more
details).

! WARNING

The muffler on this generator is only designed
for outdoor portable applications.
Do not
operate indoors under any conditions. Never operate a generator set
with a worn or defective muffler or exhaust manifold. A defective
muffler and manifold must be replaced. Never operate the generator
set without a muffler. Do not touch the muffler when hot or severe
burns will occur. Do not extend exhaust lines or use other than the
engine manufacturers recommended muffler.

Page 4

Use extreme care not to tilt the generator set
with the battery installed. Tipping could cause
severe eye damage and skin burns.

! DANGER

When connecting battery cables, the negative
(green) cable must not be connected and
should not be touching anything. First connect the positive (red) cable
and then connect the negative (green). When disconnecting battery
cables, first disconnect the negative (green) cable making sure it is not
touching anything and then disconnect the positive (red) cable.

Keep generator load within the receptacle and
generator nameplate rating. Overloading may
!
shorten generator life and could cause internal
generator damage. Do not exceed the receptacle ampere rating. The
complete ratings of the generator can be found on the nameplate of
the generator. The total output ampere rating on the generator
nameplate refers to the highest voltage the unit is equipped to
produce. On 120/240 volt units, this would be 240 volts. To determine
the 120 volt amperage rating double the amperage provided in the
nameplate. The nameplate ampere rating on load items to be powered
by this generator can be misleading if they are large power tools or
electric motors. These items will require 2-3 times the ampere rating
shown on their nameplates to get them started. Do not increase
engine speed to get more output from the generator. Engines operate
at 3600 RPM (for 60 hertz) and 3000 RPM (for 50 hertz). Racing the
engine could cause damage to the generator with excessive voltage
and damage to items being powered.

CAUTION

.
Battery installation and service – Be sure battery
! DANGER connections are of the correct polarity. All
electric start units use negative ground. The Red
cable is positive and the green cable is negative. Battery acid will
cause severe eye damage and skin burns. Safety glasses, gloves and
an apron must be worn when servicing lead acid batteries. Flush
immediately with water and call a physician if contact with battery acid
occurs. When connecting or disconnecting battery cables, the engine
must not be running or cranking. Batteries give off an explosive gas
when being charged. A spark or open flame could result in an
explosion. The charging circuit is operational during engine cranking
and running. The charging circuit is not designed to recharge a dead
battery but only maintain the charge in the battery. Provisions must be
made to keep the battery fully charged if the generator will not be
frequently run as in a permanent installation or if the battery is to be
stored for a long period of time or if it is located in an unheated room to
prevent the battery from freezing. If a trickle charger is going to be
used during periods of no generator operation, be sure to disconnect
the trickle charger before starting the generator set. Check the battery
cells with a hydrometer. The specific gravity reading should be
approximately 1.280 at 80 degrees F. If one or more cells are low on
water, add distilled water, not electrolyte and recharge. Do not use
hydrant or well water. Keep the battery case clean and dry. An
accumulation of moisture will lead to more rapid discharge and battery
failure. Keep the battery terminals clean and tight. After making
connections, coat the terminals with a light application of petroleum
jelly or grease to retard corrosion. Accidental ground out of the battery
terminal by tools, gasoline cans or when installing or removing battery
cables could cause a spark, which might result in a battery gas
explosion or fire. An open flame or lit cigarette will have the same
effect. Battery terminals and connections must be tight. When
installing the battery cables, always connect the negative cable last.
When disconnecting the battery cables, always disconnect the
negative cable first. (Figure 2)

Disconnecting the load

!

CAUTION

!

CAUTION

The generator set is inherently self-regulating and
its output automatically adjusts to the load. The
generator will not be damaged if it is operated at no load condition
except air-cooled diesel powered units. The engine governor will
compensate for load variations. It is desirable to gradually reduce the
load if possible. Voltage sensitive items such as TV’s, computers,
amplifiers, etc should be removed first.

RECEPTACLE UTILIZATION

Do not exceed the amperage rating on the outlet
receptacles. This will cause receptacles burnouts
and could cause internal damage to the generator. The operator must
realize that this generator is not an unlimited source of power and heed
generator and receptacles ratings. The nameplate ratings can be
obtained through a combination of the receptacles or a single
receptacle if the generator and/or the receptacle ampere rating is not
exceeded. Some 125 volt plugs on items to be powered from the
generator must be of the 3 prong grounded type. Only 3 wire
extension cords and 3 wire or double insulated power tools should be
used with the generator. Do not overload the generator. Some
straight blade 125 volt receptacles are ground fault circuit interrupter
protected. Twist lock receptacles are not ground fault circuit interrupter
equipped.
Consult the National Electrical Code, Underwriters
Laboratories and/or the Canadian Standards Association Code for
ground fault protection requirements for temporary installations or
usage.

FULL POWER SWITCH (LR50/55/60 MODELS)
Always place the full power toggle switch on the control panel in the up
(120 volt) position when only using 120 volt devices to obtain the full
power of the generator. When the full power switch is in the up
position (marked 120 volts), the generator windings are connected in a
parallel mode making all of the output of the generator 120 volts and
the 240 volt receptacle is not functional. If 240 volts is required, place
the switch in the down position (120 and 240 volts). The 240 volt
receptacle now has the full power of the generator. Each 120 volt
receptacle has only ½ of the normal power. It is recommended to
remove all electrical loads before changing the switch to either
position. The position of the switch affects the reading of the
voltmeter. In the up position the volt-meter will read 120 volts and in
the down position the meter will read 240 volts.

STOPPING THE ENGINE

GENERATOR VENTILATION OPERATION

Adequate ventilation must be provided for safe
efficient operation. The exhaust products of the
engine contains invisible carbon monoxide which is poisonous and can
cause death. Operate only outdoors and NEVER indoors. Operation
in small compartments will cause the engine to over heat, generator
windings will over heat and all warranties are voided. Mounting the
generator in an enclosed compartment such as an RV or in the back
end of a truck is prohibited and can cause death and damage to the
equipment.

For all models gradually remove the load from the generator. To stop
the engine, turn off the key or switch off until the engine comes to a
complete stop. On all diesel models you must keep pressure on the
stop lever until the engine comes to a complete stop.

APPLYING ELECTRIC LOADS
Allow the engine to reach normal operating temperature (2 – 3
minutes) before connecting any load to the generator. Connect the
load be inserting the plugs into the proper receptacles. The load
should be applied gradually. If the load consists of large electric
motors, they should be individually started with the largest motor first.
Smaller loads can then be applied.

Page 5

The mounting of the LP and NG generators are identical to the
gasoline units.

HIGH TEMPERATURE OPERATION
Be sure airflow to and from generator is not obstructed. Keep the
generator as free from dirt as possible. Engine housing must be
properly installed and undamaged.

There is no need to use a choke to start either the LP or NG units. DO
NOT adjust the KN regulator as it has been preset. Be sure to check
all connections for leaks with soap and water and stop any leaks. All
LP and NG units are derated as the LP or NG fuel reduces engine out
put slightly versus gasoline.

LOW TEMPERATURE OPERATION
To aid in cold weather starting, use the correct SAE oil. Use only fresh
unleaded gasoline. Diesel engine use No2 diesel in normal weather
and No1 in cold weather. If possible, keep the generator set in a warm
location until needed and they move the unit outside and immediately
start the engine.

Operate only in well ventilated area. LP gas is heavier than air and
may settle in low places. Avoid cutting or welding near fuel lines or
tanks. When servicing shut off all fuel lines, eliminate all possible
outside sources of ignition and utilize qualified LP and or NG
personnel. See connection drawing for the location for the flexible fuel
line.

IDLER OPERATION
All LR Contractor units feature an easy idle that slows the engine
speed down when there is no electrical load on the generator. Diesel
powered units, medium duty A, LA and LR units and three phase units
do not have a low idling system. The generator set should be started
with the idler switch in the off position. After the engine has warmed
up (2-3 minutes), turn the idler switch to the on position. The engine
speed will decrease if there is no load on the generator. On some
models there is a time delay of about 10 to 12 seconds before the
engine will idle down. When an electrical load is applied, the engine
speed will automatically return to normal operation and produce the
rated voltage. A battery MUST be connected to the engine for the idler
to work on all 7000, 8000, 10000, 12000, 15000 and 18000 watt
models.

!

CAUTION

OPERATING SAFE GENS

Start the engine and verify that the volt meter
reads 240 volts. The ground fault sensing module on the control panel
should have a green light illuminated. All receptacles 120 and 240
volts will be operating. If a ground fault occurs on any receptacles, a
red light will be illuminated on the ground fault sensing module and the
main circuit breaker will trip showing a red switch with all the power to
all receptacles cut off. To correct the ground fault, with the engine
running, remove all loads to all receptacles, push reset on the ground
fault sensing module and push the main circuit breaker to ON (red
should not be showing on the main circuit breaker). If the ground fault
continues with no load on the generator, consult an authorized service
station. If the ground fault occurs again with a load plugged into any
receptacle, disconnect the load, reset the ground fault sensing module
and the main circuit breaker and try a different load into any
receptacle. With this other load and no ground fault occurring the
ground fault is in the original extension cord or load and must be
corrected or replaced before using this generator set.
It is recommended to regularly, at least once a month, start the
engine, press test on the ground fault sensing module and then press
reset and push the main circuit breaker to ON.

Indoor installations are prohibited.
The
generator does not have output capacity to power your entire home.
Most home utility commercial electric service is in excess of 100 amps
at 240 volts, which is in excess of the generator set. Because of this,
only key items can be powered during a utility power outage up to the
ampere rating of the generator. Installing and wiring a stand by
generator is NOT a do it yourself project. Consult a licensed
electrician or electrical contractor.

ONLY, all installations must be done by a qualified electrician or
contractor and MUST comply with all national and local codes,
standards and regulations. This is not a do it yourself project!
All units have a special vapor fuel carburetor for LP or NG operation
with a vacuum safety shut down and an electric solenoid fuel shut
down. All incoming fuel supplies, both LP and NG must have a
primary fuel regulator with output of 11 inches of water column
pressure. The regulator on the generator is a secondary regulator.
Fuel pressures too high or too low will cause problems with the
generator set. There must be a manual fuel shut off valve within sight
of the generator set. The flexible fuel line included with the generator
set MUST be used as vibration occurs and will cause solid fuel pipe
connections to break if the flexible fuel line is not used. The incoming
fuel line is recommended to be 1.0 inches. The actual fuel connections
on the generator set are 3/4” NPT. Do not have the incoming fuel line
near the engine muffler or manifold for safety.
After all fuel line connections have been made but before the flexible
fuel connection is connected to the hard fuel pipe connections,
ventilate the area, be sure there are no open flames, no smoking, no
pilot lights and turn on the fuel line for about 5 to 10 seconds to blow
out any pipe tape or pipe dope out of the lines. Be sure to wear
protective glasses. This will prevent dirt from entering the fuel
regulator on the generator set. Do not remove the cover from the
solenoid valve until you are ready to make pipe connections.

GENERATOR AND UTILITY POWER ISOLATION METHODS
If utilizing existing home circuits to power the
emergency load provide a positive means of
insuring that the commercial power and portable
generator is never fed to the load at the same time. Never connect the
generator output to any live home electric circuit(s). The usual means
of providing this isolation is to incorporate a suitably rated double pole
double throw manual transfer switch UL listed. Figure 3 The National
Electrical Code, the state of California, most state and local codes and
Canadian Hydro requires an isolation switch between the generator
and the utility line. A potential hazard exists during a power outage if
the generator output is connected to the dead home circuits and no
means is provided to isolate the home circuits from the commercial

utility power source. Repair personnel working to restore service to
normal will open a switch between the main power supply and the
location they are working. The repairman has every reason to believe
that the line he is working on is electrically dead. If the home circuits
are not isolated, the generator output will back feed through the home
circuit up to the utility line and the repairman will be electrocuted when
he attempts repairs. If normal power and the generator are not
isolated and the normal power is suddenly restored while the generator
is operating, severe damage to the generator will occur and possibly
damage and or a fire to the home.

Add the watts required for starting electric motors with the
watts required for all other loads and you now known the
size generator you need to operate your loads. Always start
the largest size motor first and then the next smallest.

SUGGESTED HOME STANDBY INSTALLATION
A typical installation with an outdoor connection box, cord set and
manual transfer switch is shown in figure 4. The installation of the
outdoor connection box and manual transfer switch must be performed
by a licensed electrician or contractor. Store the generator in a warm
and dry location. During a utility power failure, carry the generator
outdoors to a flat, dry location such as a driveway or walk way. Use a
connection box and cord set as shown to connect your 240 volts from
the generator to the home. Turn off the lights and appliances that were
on before the utility failure. This prevents a possible overloading of the
generator. Start the engine, wait 2-3 minutes for the engine to warm
up and then throw the manual transfer switch to the generator position.
You may then apply various electrical loads being careful not to
exceed the capacity of the generator. When the utility power is
restored, throw the manual transfer switch to the normal position. Your
home circuits are now being powered by the utility. Disconnect the
cord set from the generator and shut the generator down. Service the
engine as required.

INFREQUENT SERVICE
If the generator set is used infrequently, extended shut down periods
can result in difficult engine starting. If let to stand in the engine for a
long time (over 6 months) gasoline will tend to form a varnish like
substance which will clog up to the fuel system and the carburetor.
The result will be a hard start engine. Check with your local engine
manufacturer dealer for their recommendation of a gasoline additive to
prevent varnish formation. To eliminate hard starting, run the
generator at least 10 minutes every 4 to 6 weeks. This will insure that
the engine seals will not dry out and cause oil leaks and compression
problems. The use of a fuel additive such as Sta-Bil or any other
equivalent will minimize the formation of gum deposits. Capacitors
tend to slowly discharge over prolonged periods of time. See the web
site www.voltmaster.com for flashing capacitors.

EMERGENCY CIRCUIT ISOLATION METHOD
A.

OUT OF SERVICE PROTECTION
If the generator set will be out of service for 6 months or longer, the
following is recommended:

Run the unit until it reaches normal operating temperature
(about 10 minutes) and shut it down

Drain the fuel from the carburetor bowl

Drain the oil from the engine base while the engine is still
warm. Fill with fresh oil.

Remove the spark plug(s), pour 1 oz of engine oil into the
cylinder(s), crank the engine slowly and replace the spark
plug(s) but do not tighten

Service the air cleaner

Plug the exhaust outlet to prevent moisture, bugs and dirt.

Clean off dirt and grease

Put a cover over the unit and store avoiding extreme heat or
cold.

Before restarting, remove protective cover, remove spark
plug(s), crank the engine slowly, replace the spark plug(s)
and tighten them.

B.

WATTAGE REQUIREMENTS
When determining the generator load, it is critical for you to decide
what equipment and or appliances you want to run at the same time.
The following steps will help you determine what size load this
generator can power. Electric motors present a special problem when
figuring the proper generator size.

Make 2 lists, one of the electric motors and the other of all
lights, small appliances etc that must be powered by the
generator. For stand by emergency service you should
include only essential equipment (refrigerator, sump pump,
water pump, heat) that must be kept in service.

Enter the watts required to operate each item (except
motors). This wattage can usually be found on the appliance
nameplate. If the wattage is not listed, you can determine
the wattage by multiplying the voltage times the amperage,
which equals wattage for single-phase equipment.

Electric motors usually require 3 – 4 times nameplate rating
to start (locked rotor current). For example, if the electric
motor nameplate states 10 amps at 120 volts the 10 A X 120
V = 1200 running watts. This would mean that you would
need about 30 amps on one 120 volt circuit to start this
motor. Electric motors will require different starting amps
depending on the application. VOLTS X AMPS = WATTS

Air compressors, circular saws, ½” drills, submersible
pumps, well pumps, inverters, air conditioners, hot air roof
welders etc require very heavy electric motor starting
amperage.
These devices require at least 3 times
nameplate ratings or more to start. Some motors such as
hair dryers, food mixers, etc require very little above the
nameplate ratings to start.

One method is to have the emergency circuits (important
items to be powered in a power outage) grouped together
and rewired into a separate junction box (this emergency
circuit must not exceed the ampere rating of the generator)
and connected to the generator by a cord set or directly
wired to the generator. The manual transfer switch with an
ampere rating equal to the ampere rating of the emergency
circuit, would then be connected between the home load
center panel and the emergency circuit junction box figure 5.
With this method it will be difficult to accidentally over load
the generator. During a power outage, start the generator
(with no load) and then place the manual transfer switch in
the generator position. The generator will now power the
emergency circuit. When the normal power is restored the
manual transfer switch should be placed in the normal
position after the generator is shut down. The emergency
circuit will now be powered by the utility power.
Another method is the TOTAL CIRCUIT ISOLATION
METHOD. If the emergency circuit are not or cannot be
rewired together in a separate junction box (figure 6) you will
have to select the circuits and appliances to be powered by
the generator. Caution must then be used to prevent the
overload of the generator. The manual transfer switch
ampere rating must be equal to the ampere rating of the
normal incoming utility service. During a power outage start
the generator with no load. All items in the home should be
turned off. Place the manual transfer switch in the generator
position. Selected emergency items can then be turned on.
Be sure these items don’t overload the generator. The
emergency items left on home circuits will now be powered
by the generator. When the normal power is restored, the
manual transfer switch is placed in the normal position and
the generator is shut down. The home electric circuits will
now be powered by the utility power source.

EXTENSION CORDS

When using extension cords, voltage drops can
cause damage to equipment being run by the generator. #12 wire is
rated at 20 amps maximum and with a 100 foot extension cord, there
will be at least a 7 volt decrease. Extension cords longer than 100 feet
will have even larger voltage decreases. It is strongly recommended to
always use #10 wire extension cords which are rated at 30 amps, The
useful life of your generator and the equipment you operate will
decrease when using #12 extension cords. See the extension cord
chart.

THREE PHASE OPERATION
All three phase generators operate similarly as single phase units.
Please note that when checking the no load voltage on any three
phase generator, the voltage will be about 10% below nameplate
rating. When a load is placed on the three phase generator, the
reactor transformer inside the generator activates and the voltage
immediately increases to the proper rated voltage of the three phase
generator. If an optional automatic voltage regulator is installed the
voltage regulation is +/- 1½%. The automatic voltage regulator is
required if relays, electric controls, etc. are used with a 3-phase motor.
A three phase plug is included with each unit.

When applying load to the generator, if the electric motor runs in
reverse direction than the motor is supposed to operate, you must stop
the generator, remove the electric load from the generator and then
reverse two of the electric motor leads on the terminal strip of the
motor. Restart the generator, apply the electric motor load and the
direction of the electric motor should be operating properly.

TRANSPORTING UNITS

All models with an “L” as the first letter have fuel
tanks with a shut-off valve located on the bottom of the tank. When
moving the unit, it is always recommended to turn the shut-off valve
(clockwise). This will prevent accidental spillage of fuel from the tank to
the carburetor float. Some “A” series models with fuel tanks mounted
directly on the engines do not have shut-off valves.
