1.Place generator on a flat, level surface.
2.Clean area around oil fill and remove yellow
oil fill cap/dipstick.
3.Wipe dipstick clean.
NOTE:
The engine is equipped with a low oil shut-off and
will stop when the oil level in the crankcase falls
below the threshold level.
NOTE:
We consider the first 5 hours of run time to be
the break-in period for the unit. During the break
in period stay at or below 50% of the running
watt rating and vary the load occasionally to allow
stator windings to heat and cool. Adjusting the
load will also cause engine speed to vary and help
seat piston rings.
CAUTION
The unit is equipped with a low oil shutdown.If
the oil level becomes lower than required,the
sensor will activate a warning device or stop the
engine.
If generator shuts off and the oil level is within
specifications, check to see if generator is sitting
at an angle that forces oil to shift. Place on an
even surface to correct this. If engine fails to
start, the oil level may not be sufficient to
deactivate low oil level switch. Make sure the
sump is completely full of oil.

DO NOT mix oil in gasoline.
DO NOT modify engine to run on alternate fuels.
•
•
•
WARNING
Fuel and its vapors are extremely flammable
and explosive which could cause burns, fire or
explosion resulting in death, serious injury
and/or property damage.
WHEN ADDING FUEL
Fill fuel tank outdoors.
DO NOT overfill tank. Allow space for fuel
expansion. If the tank is overfilled, fuel
can overflow onto a hot engine and cause fire
or explosion. Wipe up any spilled fuel
immediately.
If fuel spills, wait until it evaporates before
starting engine.
Keep fuel away from sparks, open flames,
pilot lights, heat, and other ignition sources.
Check fuel lines, tank, cap and fittings
frequently for cracks or leaks. Replace if
necessary.
DO NOT light a cigarette or smoke when
filling the fuel tank.
•
•
•
•
1.Clean area around fuel fill cap, remove cap.
2.Slowly add unleaded fuel to fuel tank. Be
careful not to fill above the red fuel level
indicator . This allows adequate space for
fuel expansion.
3.Install fuel cap and let any spilled fuel
evaporate before starting engine or wipe up
any spilled gasoline.
CAUTION
Slowly add unleaded gasoline to fuel tank.
Do not overfill tank.
Do not fill above top of fuel screen. This

Operation at High Altitude
At altitudes over 5,000 feet(1524 meters), a
minimum 85 octane / 85 AKI (89 RON) gasoline
is acceptable.
The density of air at high altitude is lower than at
sea level. Engine power is reduced as the air mass
and air-fuel ratio decrease. Engine power and
generator output will be reduced approximately
3.5% for every 1000 feet of elevation above sea level.
This is a natural trend and cannot be changed by
IMPORTANT: It is important to prevent gum
deposits from forming in fuel system parts such
as the carburetor, fuel hose or tank during
storage. Alcohol-blended fuels (called gasohol,
ethanol or methanol) can attract moisture, which
leads to separation and formation of acids during
storage. Acidic gas can damage the fuel system
of an engine while in storage. To avoid engine
problems, the fuel system should be emptied
before storage of 30 days or longer. See the
" Long Term Storage" section. Never use engine
or carburetor cleaner products in the fuel tank
as permanent damage may occur.

Starting the Generator
1. Before starting the generator, check for loose
or missing parts and for any damage which
may have occurred during shipment.
2. Check oil level and fuel.
6. Move the choke lever to the “START” position.
5. Flip the engine switch to the “ON”(l) position.
8. Do not over-choke. As soon as engine starts
and warms up, move the choke lever to the
“RUN” position.
9. Allow generator to run at no load for few
minutes upon each initial start-up to permit
engine and generator to stablize.
WARNING
When starting engine, pull cord slowly until
resistance is felt and then pull rapidly to avoid
kickback.
4. Turn the fuel valve to the “ON” (l)position.
7. Pull the starter cord slowly until resistance is
felt and then pull rapidly.
3. Disconnect all electrical loads from the
generator. Never start or stop the generator
with electrical devices plugged in or turned
on.
English Customer Service: 1-844-FIRMAN1
Keep choke lever in “START” position for only 1
pull of the recoil starter. After first pull, move
choke lever to the “RUN” position for up to the
next 3 pulls of the recoil starter. Too much choke
leads to sparkplug fouling/engine flooding due
to the lack of incoming air. This will cause the
engine not to start.
Page 16
Connecting Electrical Loads
1.Let engine stabilize and warm up for a few
minutes after starting.
2.Ensure circuit breaker on control panel is in
on position.
3.Plug in and turn on the desired 120 or 240 Volt
AC, single phase, 60Hz electrical loads. It is
better to attach the item with largest load first.
Stopping the Engine
1. Turn off and remove entire electrical loads.
Never start or stop the generator with
electrical devices plugged in or turned on.
This unit has been pretested and adjusted to
handle its full capacity. Before starting the
generator, disconnect all load. Apply load only
after generator is running. Voltage is regulated
via the engine speed adjusted at the factory for
correct output. Readjusting will void warranty.
CAUTION
When applying a load, do not exceed the maximum
wattage rating of the generator when using one or
more receptacles. Also, do not exceed the amperage
rating of any one receptacle.
Do not apply heavy electrical load during break-in
period (the first five hours of operations).
WARNING

SERVICE AND STORAGE
DANGER
Any damages or hazards caused by using
improper fuel, improperly stored fuel, and/
or improperly formulated stabilizers, are not
covered by manufacturer's warranty.
Infrequent Service
If the unit is used infrequently, difficult starting
may result. To eliminate hard starting, follow
these instructions:
1. Run the generator at least 30 minutes every
month.
2. Run the generator, then close the fuel shut-off
valve and allow the unit to run until the engine
stops.
3. Move the engine switch to the "OFF" position.
Long Term Storage
It is important to prevent gum deposits from forming
in essential fuel system parts such as the carburetor,
fuel hoses or tank during storage. Also, experience
indicates that alcohol-blended fuels (called gasohol,
ethanol or methanol) can attract moisture, which leads
to separation and formation of acids during storage.
Acidic gas can damage the fuel system of an engine
while in storage.
When the generator set is not being operated, or
is being stored for more than one month, follow
these instructions to avoid engine problems:
•
1-ADD a properly formulated commercially FUEL
STABILIZER to the tank if it is not already added.
2-Operate the engine for 5-10 minutes to circulate
treated fuel into fuel lines and carburetor before
3- After engine cools down, remove all gasoline
from the fuel tank. Use a commercially available,
non-conductive vacuum siphon.
shutdown.
Drain fuel into approved container outdoors,
away from open flame. Be sure engine is cool.
Do not smoke.
4-FUEL STARVATION: Start and run the generator
until it stops from lack of fuel. This will dry out all
remaining fuel in tank, fuel lines and carburetor.
7-Remove spark plug and pour about one teaspoon
of engine oil through the spark plug hole, then pull
the recoil starter several times to distribute the oil for
lubricating the cylinder. Reattach the spark plug.
Pull recoil slowly until resistance is felt. This will
close the valves so moisture cannot enter engine
cylinder. Gently release recoil starter.
5-Allow the unit to cool entirely before cleaning
and storage.
6-Change oil with recommended grade oil.
8-Keep the engine switch and fuel valve on “OFF”
position.
9-Cover the unit and store in a clean, dry place
out of direct sunlight. NEVER USE WATER TO
CLEAN GENERATOR.
NOTE:
We recommend always using a fuel stabilizer.
A FUEL STABLIZER will minimize the formula-
tion of fuel gum deposits during storage, the
fuel stabilizer can be added to the gasoline in
the fuel tank, or into the gasoline in a storage
container.
•
If it is not practical to empty the fuel tank and
the unit is to be stored for some time, use a
commercially available FUEL STABILIZER added
to the gasoline to increase the life of the gasoline.
Run the unit for 5-10 minutes, turn off the fuel
valve and allow to run until engine stops from
lack of fuel (FUEL STARVATION).
•
Do not store gasoline from one season to
another season.
