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.

1. Remove the spark plug wire from spark plug.
2. Remove the nut and bolt from the negative(-) and
positive(+) posts.
3. Loosen and remove the screw A on the battery
holding bracket.
4. Remove the battery and recycle.
5. Install the new battery with following specication:
12V sealed lead acid 7.5AH
LXWXH: 5.95X2.55X3.82 in.
6. Connect the red positive(+) battery cable to
the battery rst.
7. Connect the black positive(-) battery cable
to the battery second.
8. Cover the posts with boots.
9. Install the spark plug wire onto spark plug.
The battery powers the starter motor and control module. This portable generator is equipped with an
automatic battery charging circuit. The battery will receive charging voltage only when the engine is
running. The battery will maintain a proper charge if the portable generator is used on a regular basis
(about once every two weeks). If it is used less frequently, the battery should be connected to a trickle
charger (not included) or battery maintainer (not included) to keep the battery properly charged. If the
battery is not able to start the engine, it can be started manually only in the GAS position by pulling the
engine recoil cord. If the battery voltage is extremely low, the charging circuit may not be able to re-
charge the battery. In this case, the battery must be connected to a standard automotive style battery
charger for recharging before it can be used.

MAINTENANCE - STORAGE
GENERATOR MAINTENANCE
● Run the generator at least 30 minutes every month.
● Make certain that the portable generator is kept clean and dry.
● Do not expose the unit to excessive dust, dirt, moisture or corrosive vapors.
● Do not insert any objects through cooling slots.
● Before each use inspect underneath the generator for signs of oil or fuel. Clean any accumulated
debris. Keep area around muer free from any debris. Use a soft bristle brush to remove dirt or caked
on oil. Use a damp cloth to clean all exterior surfaces.
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.
8.Cover and store the unit in a clean, dry place out of
direct sunlight.
NOTICE
Any damage or hazards caused by using
improper fuel, improperly stored fuel, and/or improperly
formulated stabilizers, are not covered by manufacturer's
warranty.
Do not store gasoline from one season to another
season.

CALIFORNIA AND FEDERAL EXHAUST AND EVAPORATIVE EMISSIONS CONTROL WARRANTY
STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board, US Environmental Protection Agency (“US EPA”) and FIRMAN
POWER EQUIPMENT INC.(FIRMAN) are pleased to explain the emissions control systems warranty
on your 2025-2026 or later Small O-Road Engine (“SORE”) and engine powered equipment. In
California, new equipment that use small o-road engines must be designed, built and equipped to
meet the State’s stringent anti-smog standards. FIRMAN must warrant the emissions control systems
on your SORE and engine powered equipment for the periods of time listed below provided there has
been no abuse, neglect or improper maintenance of your small o-road engine or equipment leading
to the failure of the emissions control system.
Your emissions control system may include parts such as the carburetor or fuel-injection system, the
ignition system, catalytic converter, fuel tanks, fuel lines (for liquid fuel and fuel vapors), fuel caps,
valves, canisters, lters, clamps and other associated components. Also included may be hoses,
belts, connectors, and other emission-related assemblies.
Where a warrantable condition exists, FIRMAN will repair your SORE and engine powered equipment
at no cost to you including diagnosis, parts and labor.
MANUFACTURER’S WARRANTY COVERAGE:
The exhaust and evaporative emissions control system on your small o-road engine and engine
powered equipment is warranted for two years. If any emissions-related part on your small o-road
engine and engine powered equipment is defective, the part will be repaired or replaced by FIRMAN.
OWNER’S WARRANTY RESPONSIBILITIES:
As the SORE and engine powered equipment owner, you are responsible for the performance of
the required maintenance listed in your operator’s manual. FIRMAN recommends that you retain all
receipts covering maintenance on your SORE and engine powered equipment, but FIRMAN cannot
deny warranty coverage solely for the lack of receipts or for your failure to ensure the performance of
all scheduled maintenance.
As the SORE and engine powered equipment owner, you should however be aware that FIRMAN may
deny you warranty coverage if your small o-road engine or engine powered equipment or a part has
failed due to abuse, neglect, or improper maintenance or unapproved modications.
You are responsible for presenting your small o-road engine and engine powered equipment to a
FIRMAN distribution center or service center as soon as the problem exists. The warranty repairs
shall be completed in a reasonable amount of time, not to exceed 30 days.
If you have any questions regarding your warranty rights and responsibilities, you should contact
FIRMAN at 1-844-347-6261.
