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.

2. Loosen the cover screw and remove the

maintenance cover.

3. Clean area around oil ll and remove yellow oil

ll cap/dipstick.

4. Wipe dipstick clean.

5. 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 overll. Overlling could cause

engine starting problems or engine damage.

6. Replace oil ll cap/dipstick and fully tighten.

7. Reinstall maintenance cover and tighten screws.

8. 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 specications, 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.

may be a decrease in power. Maximum wattage and current are subject to and limited by such factors

as ambient temperature, altitude, engine conditions etc.

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 mu󰀪er 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 qualied plumber.

● If you smell gas, close o󰀨 all gas sources and contact a qualied 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 conned / 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 conict with any local,

state, or national code. If in doubt, always follow local codes.

LPG

● 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-qualication 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 di󰀨erent 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.

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 su󰀨er 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 conrm 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

Surge Protection

There is a remote chance that voltage uctuations may impair the proper functioning of some sensitive

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 a󰀨ected

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. Set voltage selector switch to either 120 Volt or 240 Volt position. When 120 volts is selected only

120 volts is available. When 240 Volt position is selected only 120/240 volts is available.

5. Plug in and turn on the rst item. It is best to attach the item with the largest load rst.

6. Allow the engine to stabilize.

7. Plug in and turn on the next item.

8. Allow the engine to stabilize.

9. Repeat steps 6-7 for each additional item.

Description

OPERATING INSTRUCTIONS

Economy Control Switch

12V DC Outlet (Battery Charger)

The Economy Control switch can be activated in order to minimize fuel

consumption and noise while operating the unit during times of reduced

electrical output, allowing the engine speed to idle during periods of

non-use. The engine speed returns to normal when an electrical load is

connected. When the economy switch is o󰀨, the engine runs at normal

speed continuously.

NOTICE

For periods of high electrical load or momentary uctuations,

the Economy Control Switch should be turned OFF.

The amount of current owing 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 discon-

nected from the battery after a maximum time on charge. Normally a period of 30 to 120 minutes is

su󰀩cient to recharge a weak battery. The charge level of the battery should be checked periodically.

NOTICE

● For use with 12V direct current outlet, always keep the ECO mode deactivated (OFF Position).

● You can use the 12V direct current outlet and the 120V current at the same time, but keep the ECO

mode deactivated (OFF Position) at all times.

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.

WARNING!

● Storage batteries give o󰀨 EXPLOSIVE hydrogen gas while charging. Do not allow smoking, open

ames, sparks, or spark producing equipment in the area while charging.

● Battery electrolyte uid is comprised of sulfuric acid that can be very dangerous and cause severe

burns. Do not allow this uid to contact eyes, skin, clothing, etc. If contact or spillage does occur, ush

the area with water immediately.

● Do not continue to charge a battery that becomes hot or is fully charged.

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.

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.

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.

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:

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 modications.

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.
