WARNING! This product can expose you to chemicals including gasoline engine
exhaust, which is known to the State of California to cause cancer, and carbon
monoxide, which is known to the State of California to cause birth defects or other
reproductive harm. For more information go to www.P65Warnings.ca.gov.
This outdoor generator can be used to power outdoor items using extension cords or to restore
home power using a transfer switch. A transfer switch is a separate device installed by a licensed
electrician that allows the portable generator to be cord connected, using either of the 120/240V
receptacles, directly into your home’s electrical system. Install a listed transfer switch as soon as
possible if this generator will be used to restore power to your home.
NOTICE If you have questions about intended use, contact FIRMAN customer service. This portable
generator is designed to be used only with FIRMAN authorized parts.
The generator has a system ground that connects the generator frame components to the ground
terminals on the AC output receptacles. The system ground is connected to the AC neutral wire.
The neutral is bonded to the generator frame.
System Ground
There may be Federal or State regulations, local codes, or ordinances that apply to the intended
use of the generator. Consult a qualified electrician, electrical inspector, or the local agency
having jurisdiction. This generator is not intended to be used at a construction site or similar
activity as defined by NFPA 70-2020 (NEC) section 590.6.
Compliance Requirements
Connections to your home’s electrical system must use a listed* transfer switch installed by a
licensed electrician. The connection must isolate the generator power from the utility power and
comply with all applicable laws and electrical codes.

OPERATION
1. Location
DANGER! Engine exhaust contains carbon monoxide, a poisonous gas that could kill
you in minutes. You CANNOT smell it, see it, or taste it. Even if you do not smell exhaust
fumes, you could still be exposed to carbon monoxide gas.
Install battery-operated carbon monoxide alarms or plug-in carbon monoxide alarms with
battery back-up according to the manufacturer's instructions. Smoke alarms cannot detect
carbon monoxide gas.
Do not run this portable generator inside homes, garages, basements, crawlspaces, sheds, or
other partially-enclosed spaces even if using fans or opening doors and windows for ventilation.
Carbon monoxide can quickly build up in these spaces and can linger for hours, even after this

upper limit "H" mark on the dipstick. Be careful not to overfill. Overfilling could cause engine
starting problems or engine damage.
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.
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 off and the oil level is within specifications, 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.

Connecting LPG/ NG Fuel
WARNING! Liquid Petroleum gas (LPG) and Natural Gas (NG) are extremely
flammable which could cause burns or fire resulting in death or serious injury.
Do not place the LPG/NG sources in the path of muffler outlet or near any ignition source.
Keep a fire 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 qualified plumber.
If you smell gas, close off all gas sources and contact a qualified plumber to inspect and
repair the LPG or NG system.
Prior to each days first 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 confined / 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 flexible fuel run. An approved flexible
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 conflict 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-qualification date on the cylinder has not expired.
All new cylinders must be purged of air and moisture prior to filling. 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.

Battery Replacement
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 re-charging before it can be used.

It is important to prevent gum deposits from forming in essential fuel system components such
as the carburetor, fuel hoses or tank during storage. Alcohol-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.
Long Term Storage
When the generator set is being stored for more than one month, follow these instructions to avoid
engine problems:
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.
WARNING! Fuel and its vapors are extremely flammable which could cause burns
or fire resulting in death or serious injury.
1-Treat any stored fuel with fuel stabilizer.
2-When storing generator with gasoline in fuel tank, operate the engine for 5-10 minutes to
circulate treated fuel into fuel lines and carburetor before shutdown.
3- There is no need to drain gasoline from the generator fuel tank if fuel stabilizer is added.
4-FUEL STARVATION: If you elect to drain fuel tank move generator outdoors. Once fuel tank is
drained turn main fuel selector switch to GAS position. Start and run the portable generator
outdoors until engine stops from lack of gasoline. This will drain remaining gasoline from tank,
fuel lines, and carburetor.
5-Always turn main fuel selector switch to OFF position prior to storage.
6-Allow the portable generator to cool before cleaning and storage.
7-Change oil .
8-Remove spark plug boot and spark plug. Pour about one teaspoon of engine oil through the
spark plug hole, then slowly pull the recoil starter several times to distribute the oil in the
cylinder. Reinstall the spark plug and attach the spark plug boot. Pull recoil slowly until resistance
is felt. This will close the valves so no moisture enters the engine cylinder.
9-Cover the portable generator and store in a clean, dry place out of direct sunlight and away from
any ignition sources.
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
FIRMAN POWER EQUIPMENT INC.
Emission Control System Warranty
The warranty period begins on the date the engine/equipment is delivered to an ultimate purchaser. FIRMAN warrants to the ultimate
purchaser and each subsequent purchaser that the engine is:
Designed, built, and equipped so as to conform with all applicable regulations adopted by the Air Resources Board and US EPA;
and Free from defects in materials and workmanship that cause the failure of a warranted part to be identical in all material
respects to the part as described in the engine manufacturers application for certification.
The warranty on emissions-related parts is as follows:
(1) Any warranted part that is not scheduled for replacement as required maintenance in the owner's manual supplied, is
warranted for the warranty period stated above. If any such part fails during the period of warranty coverage, the part will be
repaired or replaced by FIRMAN at no charge to the owner. Any such part repaired or replaced under the warranty will be
warranted for the remaining warranty period.
(2) Any warranted part that is scheduled only for regular inspection in the owner's manual supplied, is warranted for the warranty
period stated above. Any such part repaired or replaced under warranty will be warranted for the remaining warranty period.
(3) Any warranted part that is scheduled for replacement as required maintenance in the owner's manual supplied, is warranted
for the period of time prior to the first scheduled replacement point for that part. If the part fails prior to the first scheduled
replacement, the part will be repaired or replaced by FIRMAN at no charge to the owner. Any such part repaired or replaced
under warranty will be warranted for the remainder of the period prior to the first scheduled replacement point for the part.
(4) Repair or replacement of any warranted part under the warranty must be performed at no charge to the owner at a warranty
station.
(5) Notwithstanding the provisions of Subsection (4) above, warranty services or repairs must be provided by FIRMAN that
are franchised to service the subject engines.
(6) The owner must not be charged for diagnostic labor that leads to the determination that a warranted part is in fact defective,
provided that such diagnostic work is performed at a warranty station.
(7) FIRMAN is liable for damages to other engine components proximately caused by a failure under warranty of any
warranted part.
MANUFACTURER'S WARRANTY COVERAGE:
The exhaust and evaporative emissions control system on your small off-road engine and engine powered equipment is warranted
for two years. If any emissions-related part on your small off-road engine and engine powered equipment is defective, the part will
be repaired or replaced by FIRMAN.
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 2022-2023 or later Small Off-Road
Engine (“SORE”) and engine powered equipment. In California, new equipment that use small off-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 off-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, filters, 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.
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 off-road engine or engine powered equipment or a part has failed due to abuse, neglect, or improper
maintenance or unapproved modifications.
You are responsible for presenting your small off-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.
