OPERATION
Surge Protection
There is a remote chance that voltage fluctuations 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 affected by the portable generator’s momentary voltage fluctuations. While there is no
way to prevent all voltage fluctuations, 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 fluctuations.
Economy Control Switch
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 off, the engine runs at normal speed continuously.
For periods of high electrical load or momentary fluctuations, the Economy Control Switch should
be turned OFF.
12V DC Outlet (Battery Charger)
The 12V DC outlet is ONLY to be used with the supplied 12V battery charging cable. The DC output
is unregulated and will damage other 12V DC products.
The amount of current flowing 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 disconnected
from the battery after a maximum time on charge. Normally a period of 30 to 120 minutes is sufficient
to recharge a weak battery. The charge level of the battery should be checked periodically.
NOTICE
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.

When Transporting Generator
Transport with fuel tank EMPTY or with fuel switch in OFF position.
Do not tip generator at an angle which causes fuel to spill.
ENGINE MAINTENANCE
To prevent accidental starting, remove and ground spark plug wire before performing any service.
Change Engine Oil
Change engine oil every 100 hours. (for a new engine, change oil after 25 hours.)
If you are using your generator under extremely dirty or dusty conditions, or in extremely hot
weather change the oil more often.

Inspect Muffler and Spark Arrester
1. Inspect the muffler for cracks, corrosion, or other damage.
2. Remove the screw securing the spark arrester in place and then remove it from muffler.
3. Carefully remove the carbon deposits from the spark arrester screen with a wire brush.
4. Replace the spark arrester if it is damaged. If replacement parts are required, make sure to use
only FIRMAN original equipment replacement parts.
5. Position the spark arrester in the muffler and attach with the screw.
NOTICE Failure to clean or replace spark arrester may result in decreased engine performance.
GENERATOR MAINTENANCE
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 muffler 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.
26
Run the generator at least 30 minutes every month.
Maintenance - Storage
English Customer Service: 1-844-FIRMAN1
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.
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 fuel valve to on 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 fuel valve 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
Pull recoil slowly until resistance is felt. This will close the valves so no moisture enters the engine
cylinder. Reinstall the spark plug and attach the spark plug boot.
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.
