120VAC, 20AMP GFCI RECEPTACLE
This unit is equipped with a ground fault circuit
interrupter (GFCI). This device meets applicable
federal, state and local codes .
A GFCI receptacle does NOT protect against
circuit overloads, short circuits, or shocks. For
example, electric shock can still occur if a person
touches charged electrical wires while standing
on a non-conducting surface, such as a wood floor.
Definition: Instead of following its normal safe
path, electricity passes through a persons body
to reach the ground. For example, a defective
appliance can cause a ground fault.
A GFCI receptacle is different from conventional
receptacles. In the event of a ground fault, a GFCI
will trip and quickly stop the flow of electricity to
prevent serious injury.
1. Plug a test lamp into the receptacle.
2. Start the generator, the test lamp should be on.
3. Press the “Test” button located on the front
of the receptacle to trip the device.
4. This should stop the flow of electricity making
the lamp shut off. The GFCI’s indicator light comes
off.

5. To restore the flow of electricity, press the
“RESET” button on the front of the receptacle.
If the GFCI does not perform in this manner, do
not use the receptacle. Contact a local service
dealer or costumer service.
6. This outlet is protected against overload by
a 20A push-to-reset circuit breaker. Use the
outlet to power 120V AC, single-phase, 60 Hz,
electrical loads requiring up to a combined
2400 watts (2.4 kW) or 20 amps of current.
Testing the GFCI: Test the GFCI outlet every
month as follows:
SELF-TEST OPERATION
A Self-Test GFCI receptacle has all the features
of a conventional GFCI receptacle. In addition,
this receptacle tests itself periodically to confirm
the GFCI electronics are functional. The Indicator
Light will be solid green when the GFCI is powered
from Line side and working correctly.
Self-Test Indications: If the Indicator Light is solid
orange or flashing red a problem may exist.
Press the TEST button to trip the GFCI. If unable to
Reset, replace the GFCI.

AN IMPORTANT MESSAGE ABOUT TEMPERATURE:
Your FIRMAN generator has an operating temperature range of 5°F (-15°C) to 104°F (40°C). When
operated above 73°F (23°C) there may be a decrease in power. Rated wattage is subject to, and
limited by, such factors as fuel BTU content, altitude, ambient temperature, engine conditions, etc.
Rated wattage decrease about 1% for each 10°F(6°C) above 73°F(23°C). The generator may be
operated at temperatures ranging from 5°F(-15°C) to 122°F(50°C). If the generator is exposed to
temperatures outside this range during storage, the generator should be brought back within this
range before operation.

Add Engine Oil
Page 12
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.
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.
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

Operation at High Altitude
At altitudes over 5,000 feet(1524 meters), a
minimum 85 octane gasoline is acceptable.
Engine power and generator output will be
reduced approximately 3.5% for every 1000
feet (305 m) of elevation above sea level. High
altitude may cause hard starting, increased fuel
consumption and spark plug fouling. To operate
at high altitudes FIRMAN can provide a high
altitude carburetor main jet. The alternative
main jet and installation instructions can be
obtained by contacting Customer Support.
NOTICE Operation using an alternative main
jet at elevations lower than the recommended
minimum altitude can damage the engine. For
operation at lower elevations, the standard
main jet supplied must be used. Operating the
engine with the wrong main jet may increase
exhaust emissions, fuel consumption and
reduce performance.

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.

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.
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).
Let the generator run at no-load for two
minutes to stabilize internal temperatures
of the engine and generator.
