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
Storage batteries give off EXPLOSIVE hydrogen gas while charging. Do not allow smoking,
open flames, sparks, or spark producing equipment in the area while charging.
WARNING!
Battery electrolyte fluid is comprised of sulfuric acid that can be very dangerous and cause severe

Battery Charging
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, we can use the
supplied charger plugged into the generator 12V DC Battery Charge Port to charge the battery.
1. Plug the cord from the charger into the charging port on the generator control panel.
2. Plug the charger into a 120 volt AC wall outlet.
3. There is a light on the charger that remains red until the battery is fully charged at which point
the light will turn green.
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.
