OIL AND GASOLINE
2A. Add Engine Oil
Low Oil Shutdown
OPERATING INSTRUCTIONS
We recommend using SAE 10W-30 API SL or
higher oil for best performance. Do not use special
additives. Ambient temperature determines the
proper oil viscosity for the engine. Use the chart to
select the proper oil for the outdoor temperature
range expected.
NOTICE
Do not attempt to crank or start the
engine before it has been properly lled with the
recommended type and amount of oil. Damage
due to operation with no oil will void your warranty.
1. Place generator on a at, level surface.
2. Clean area around oil ll and remove yellow oil
ll cap/dipstick.
3. Wipe dipstick clean.
4. Using oil funnel, slowly pour contents of
provided oil bottle into oil ll opening until oil
reaches upper limit "H" mark on the dipstick.
Be careful not to overll. Overlling could cause
engine starting problems or engine damage.
5. Replace oil ll 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.
The portable generator is equipped with a low oil shutdown. If the oil level drops below the minimum
required level, a sensor will activate an internal switch stopping the engine. If the engine shuts o
and the oil level is within specications, check to see if generator is sitting at an angle. Place portable
generator on an even surface to correct this. If engine fails to start, the oil level may not be high
enough to deactivate the internal low oil level switch. Make sure the sump is completely full of oil to
the upper limit (H). Do not operate engine until oil level issue is corrected. Contact FIRMAN customer
service.

OPERATING INSTRUCTIONS
Connecting LPG/ NG Fuel
WARNING! Liquid Petroleum gas (LPG) and Natural Gas (NG) are extremely
ammable which could cause burns or re resulting in death or serious injury.
● The fuel supply line must always be shut o when the engine is not running. Failure to shut
o fuel may allow fuel to leak at the generator.
● Do not place the LPG/NG sources in the path of muer outlet or near any ignition source.
● Keep a re extinguisher near the generator all the time.
● Do not use or store LPG/NG portable sources not in use near generator or in a building, garage
or enclosed area.
● All LPG/NG supply/piping lines must be installed by a qualied plumber.
● If you smell gas, close o all gas sources and contact a qualied plumber to inspect and
repair the LPG or NG system.
● Prior to each days rst use spray a soapy water solution on LPG/NG fuel connections to check
for leaks.
● Never use a gas container, LPG/NG connector hose, LPG cylinder or NG source that appears
to be damaged.
● Do not connect or disconnect the LPG/NG source in an enclosed area.
● LPG is heavier than air and can accumulate in conned / low spaces if there is a leak.
NOTICE
If a fuel supply connection is necessary it must be installed in accordance with all local
codes or regulations, or in the absence of local codes or regulations, in accordance with the
National Fuel Gas Code (NFPA 54/ANSI Z223.1) and CSA B149.1 (Natural Gas and Propane
Installation Code), as applicable. If possible the fuel supply connection should be close to the
outdoor operating location. This will reduce the cost of the exible fuel run. An approved exible
fuel line must be installed between the generator LPG/NG Hose Connector (Inlet) and the fuel
supply connection. In no case should this information be interpreted to conict with any local,
state, or national code. If in doubt, always follow local codes.
18
● Always keep the LPG cylinder in an upright position.
● Use only DOT LPG cylinders in vapor service with type 1, right hand ACME threads. Verify the
re-qualication date on the cylinder has not expired.
● All new cylinders must be purged of air and moisture prior to lling. The purging process should be
done by your propane gas supplier.
Attach the LPG regulator hose assembly (included) to the LPG hose connector (inlet) on the control
panel of the generator. Tighten the nut with a 19 mm or adjustable wrench. Remove the safety plug
or cap from the LPG cylinder valve. Attach the LPG regulator to the cylinder valve. Do not use a
wrench to tighten LPG cylinder nut. Tighten the nut by hand clockwise to a positive stop. Using a
wrench may damage LPG cylinder components.
Connect the locally approved exible fuel supply line (not included) to the LPG/NG connector (inlet)
on the control panel and the fuel Source. We recommend you use FIRMAN 25 ft Quick Connect Hose
Kit (Model 1815) or 10 ft Quick Connect Hose Kit (Model 1805) for Natural Gas (NG) connection (This
item is not included). Hose requirements may vary in dierent regions depending on local codes.
Contact your local licensed plumber to ensure complete compliance with all codes. Make sure the
NG source location and hose used allows the portable generator to be located at least 20 ft from any
occupied spaces.

deteriorating performance. In these rare situations
it can be helpful to:
● Exchanging fuel cylinders to allow the rst
cylinder to warm up, repeating as necessary.
● Placing the LPG cylinder at the end of the
generator near the handle, where engine fan air
ows out from the generator. This air is slightly
heated by air owing over the engine.
● Do not place the LPG cylinder in the path of the
muer exhaust outlet.
● The LPG cylinder and components can be
temporarily warmed by pouring warm water over
them.

OPERATING INSTRUCTIONS
This portable generator has been pretested and adjusted to handle its full capacity. The voltage is
regulated using an automatic voltage regulator (AVR). Readjusting the AVR will void warranty.
The duplex receptacle is equipped with GFCI protection. The GFCI protects against electric shock
that may be caused if you become a path which electricity travels to reach earth. Even with a GFCI
you may feel a shock, but the GFCI cuts power quickly so an average person should not suer any
injury. Manual test GFCI while generator is running to verify internal contacts will function.
●
Push the test button. The reset button will pop out, which should cut power to outlet.
●
Press the reset button until it locks in the depressed position. If the GFCI does not reset as
described do not use the receptacles. Call Firman customer service.
●
If GFCI trips while in use, reset and test the outlet. Electric cords laying on the ground with
worn insulation may trip the GFCI, only use cords in good condition.
In addition to the manual test / reset feature the GFCI receptacle tests itself periodically to conrm the
GFCI electronics are functional. The indicator light will be solid green when the GFCI is powered from
the generator and working correctly.
Self-test indications: If the indicator light is solid orange or ashing red a problem may exist.
Press the TEST button to trip the GFCI. If unable to reset, replace the GFCI

electronic equipment. Electronic devices, including computers and many programmable appliances
may use components that are designed to operate within a narrow voltage range and may be aected
by the portable generator’s momentary voltage uctuations. While there is no way to prevent all voltage
uctuations, you can take steps to protect your sensitive electronic equipment. Install a plug-in surge
suppressor on the receptacles feeding your sensitive equipment. Surge suppressors come in single or
multi-outlet styles. They are designed to protect against short duration voltage uctuations.
1. Ensure circuit breaker on control panel is in the
closed (on) position.
2. Start the generator with no electrical load
attached.
3. Allow the engine to run for several minutes to
stabilize.
4. Plug in and turn on the rst item. It is best to
attach the item with the largest load rst.
5. Allow the engine to stabilize.
6. Plug in and turn on the next item.
7. Allow the engine to stabilize.
8. Repeat steps 5-6 for each additional item.

Long Term Storage
It is important to prevent gum deposits from forming in essential fuel system components such as
the carburetor, fuel hoses or tank during storage. Ethanol-blended fuels (called gasohol, ethanol or
methanol) 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 being stored for more than one month, follow these instructions to avoid
engine problems:
WARNING!
Fuel and its vapors are extremely
ammable which could cause burns or
re resulting in death or serious injury.
Do not store fuel near any ignition sources.
When draining fuel move generator outdoors and use a
commercially available non-conductive vacuum siphon.
Fuel must be drained into an approved container.
1.Add a properly formulated fuel stabilizer to the gasoline
tank.
2.Start the generator as instructed in Starting the
Generator section.
3.Run the generator for 5-10 minutes so the treated
gasoline cycles through the fuel system.
4.Turn the main fuel selector switch to the “STORAGE
OFF” position until the engine stops. This may take 3-5
minutes. Then turn the fuel selector switch to “OFF(O)”
position.
5.Change oil after the engine cools down entirely.
6.Remove spark plug and pour about one teaspoon of
engine oil into the cylinder.
7.Pull the starter cord a few times to lubricate the cylinder
and then reinstall the spark plug.
