Add Engine Oil
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.

5.Replace oil fill cap/dipstick and fully tighten.
6.Oil level should be checked prior to each use
or at least every 8 hours of operation. Keep oil
level maintained.
4.Using oil funnel, slowly pour contents of
provided oil bottle into oil fill opening to the
"H" mark on dipstick. Be careful do not
overfill. Overfilling with oil could cause the
engine to not start or hard starting.

Add Fuel
Fuel must meet these requirements:
•Clean, fresh, unleaded gasoline.
Use regular UNLEADED gasoline with the
generator engine with a minimum 87 octane
/ 87 AKI (91 RON).
For high altitude use, see "Operation at High
Altitude".
Do not use gasoline with more than 10%
alcohol such as E85 or ethanol.
•
•
Failure to follow Operator's Manual for fuel
recommendations voids warranty.
Avoid generator damage.
DO NOT use unapproved gasoline such as E85.
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 the red line indicator.
This will allow expansion in hot weather
and prevent overflow.
•
•
•
Red Line Indicator
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.
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
adjusting the engine. At high altitudes

CAUTION

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 “CHOKE” position.
5. Flip the engine switch to the “ON”(l) position.
8. Do not over-choke. As soon as engine starts
and warm 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.
Keep choke lever in “CHOKE” 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.

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.
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).
3.Plug in and turn on the desired 120 Volt
AC, single phase, 60Hz electrical loads. It is
better to attach the item with largest load first.
12V DC Outlet (Battery Charger)
The 12V DC outlet is ONLY to be used with the
supplied 12V battery charging cable. The DC
output is unregulated and will damage other
12V DC products.
CAUTION
1. Before connecting the battery charging cable
to a battery that is installed in a vehicle, disconnect
the vehicle battery ground cable from the
negative (–) battery terminal.
Storage batteries give off EXPLOSIVE hydrogen
gas while charging. Do not allow smoking, open
flames, sparks, or spark producing equipment
in the area while charging.
WARNING
Battery electrolyte fluid is comprised of sulfuric
acid that can be very dangerous and cause severe
burns. Do not allow this fluid to contact eyes, skin,
clothing, etc. If contact or spillage does occur,
flush the area with water immediately.
WARNING
Do not continue to charge a battery that becomes
hot or is fully charged.
The amount of current flowing will depend on the
charging voltage and battery's state of charge. As
the battery becomes more fully charged, the output
current to the battery decreases and nearly becomes
constant. Taper chargers are intended to be used
with the provision that they will be disconnected
from the battery after a maximum time on charge.
Normally a period of 30 to 120 minutes is sufficient
to recharge a weak battery. The charge level of the
battery should be checked periodically.
Do not start the vehicle while the battery charging
Cable is connected and the generator is running.
It will not give the battery a boost of power. The
Vehicle or the generator may be damaged. Charge
only vented wet lead acid batteries. Other types
of batteries may burst, causing personal injury
or damage.

2. Press the engine switch to the “OFF”(O) position.
A DC circuit protector has been provided to
protect the circuit from overloads. If an overload
occurs, the circuit protector will trip. The circuit
protector may be reset by pushing the button of
the protector.
DC CIRCUIT PROTECTOR
Charging a large capacity battery or a totally
discharged battery may cause the DC breaker to
turn off. In these cases, a separate battery charger
unit connected to an AC power source is
recommended instead of the DC receptacle on
the generator.
Stopping the Engine
Let the generator run at no-load for two
minutes to stabilize internal temperatures
of the engine and generator.
1. Turn off and remove entire electrical loads.
Never start or stop the generator with
electrical devices plugged in or turned on.
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.
DO NOT stop engine by moving choke control
to “START” position.
Important: Always ensure that the Fuel Valve
and the Engine Switch are in the “OFF” position
when the engine is not in use.
If the engine will not be used for a period of two
weeks or longer, please see the Storage section
for proper engine and fuel storage.
2. Plug the battery charging cable into the DC
receptacle of the generator.
3. Connect the red (+) battery charger lead to the
red (+) battery terminal.
4. Connect the black (–) battery charger lead to
the black (–) battery terminal.
5. Start the generator.
NOTE:
When the battery circuit is in use the AC capacity
is reduced by 100 watts. Make sure the combined
load is within the rated limits.
WARNING
Do not continue to charge a battery that becomes
hot or is fully charged.
If a cover is used, do not install until unit has cooled.
3. Turn the fuel valve to the “OFF”(O) position.
Do not leave the generator until it has
completely stopped.
Do not expose to rain.
Charge only 12v lead-acid batteries. Other types
of batteries may burst causing personal injury
and damage.
Risk of explosive gas mixture. Read instructions
in owner’s guide before using charger.

Low Oil Shutdown
If the engine oil drops below a preset level, an
oil switch will stop the engine. Check oil level
with dipstick.
If oil level is between LOW and HIGH mark on
dipstick:
1.DO NOT try to restart the engine.
2.Contact an Authorized FIRMAN Service Dealer.
3.DO NOT operate engine until oil level is
corrected.
If oil level is below LOW mark on dipstick:
1.Add oil to bring level to HIGH mark.
2.Restart engine and if the engine stops again
a low oil condition may still exist. DO NOT try
to restart the engine.
3.Contact an Authorized FIRMAN Service Dealer.
4.DO NOT operate engine until oil level is
corrected.
Do Not Overload Generator
Overloading a generator in excess of its rated
wattage capacity can result in damage to the
generator and to connected electrical devices.
To prolong the life of your generator and
attached devices, follow these steps to add
electrical load:
1. Start the generator with no electrical load
attached.
2. Allow the engine to run for several minutes
to stabilize.
3. Plug in and turn on the first item. It is best to
attach the item with the largest load first.
4. Allow the engine to stabilize.
