Fuel Safety
DANGER
GASOLINE AND GASOLINE VAPORS ARE HIGHLY
FLAMMABLE AND EXPLOSIVE.
Fire or explosion can cause severe burns or death.
Unintentional startup can result in entanglement,
traumatic amputation or laceration.
Gasoline expands or contracts with ambient
temperatures. Never fill the gasoline tank to
full capacity, as gasoline needs room to expand
if temperatures rise.
Gasoline can cause a fire or explosion if ignited.
Gasoline is a liquid fuel but it’s vapors can ignite.
•
•
•
Gasoline is a skin irritant and needs to be cleaned
up immediately if spilled on skin or clothes.
•
Gasoline has a distinctive odor, this will help
detect potential leaks quickly.
•
In any gasoline fire, flames should not be
extinguished unless by doing so the fuel supply
valve can be turned OFF. This is because if a fire is
extinguished and a supply of fuel is not turned OFF,
then an explosion hazard could be created.
•
Liquid Petroleum Gas (LPG/Propane):
This generator is dual fuel and capable of running
with both gasoline and Liquid Petroleum Gas
(LPG/Propane).
•
If you smell gas: close off the gas supply. Make
sure there is no leak before using the generator.
•
•
•
•
•
•

DO NOT attempt to crank or start the engine
before it has been properly filled with the
recommended type and amount of oil. Damage
to the generator as a result of failure to follow
these instructions will void your warranty.
1.Place generator on a flat and level surface.
2.Loosen the cover screw and remove the
maintenance cover.
NOTE:
The recommended oil type is 10W-30 automotive
oil. However outdoor temperatures will determine
the space proper oil viscosity for the engine. Use the
chart to select the best for the outdoor temperature
range expected.
The engine is equipped with a low oil shut-off and
will stop when the oil level in the crankcase falls
below the threshold level.
NOTE:
We consider the first 5 hours of run time to be
the break-in period for the unit. During the break
in period stay at or below 50% of the running
watt rating and vary the load occasionally to allow
stator windings to heat and cool. Adjusting the
load will also cause engine speed to vary and help
seat piston rings.
CAUTION
The unit is equipped with a low oil shutdown.If
the oil level becomes lower than required,the
sensor will activate a warning device or stop the
engine.
If generator shuts off and the oil level is within
specifications, check to see if generator is sitting
at an angle that forces oil to shift. Place on an
even surface to correct this. If engine fails to
start, the oil level may not be sufficient to
deactivate low oil level switch. Make sure the
sump is completely full of oil.
5.Replace oil fill cap/dipstick and fully tighten.

IMPORTANT: It is important to prevent gum
deposits from forming in fuel system parts such
as the carburetor, fuel hose or tank during
storage. Alcohol-blended fuels (called gasohol,
ethanol or methanol) can 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. To avoid engine
problems, the fuel system should be emptied
before storage of 30 days or longer. See the
" Long Term Storage" section. Never use engine
or carburetor cleaner products in the fuel tank
as permanent damage may occur.

Operation at High Altitude
At altitudes over 5,000 feet(1524 meters), a
minimum 85 octane / 85 AKI (89 RON) gasoline
is acceptable.
The density of air at high altitude is lower
than at sea level. Engine power is reduced
as the air mass and air-fuel ratio decrease.
Engine power and generator output will be
reduced approximately 3.5% for every 1000 feet
of elevation above sea level. This is a
natural trend and cannot be changed by
adjusting the engine. At high altitudes
increased exhaust emissions can also result
due to the increased enrichment of the air
fuel ratio.
Other high altitude issues can include hard
starting, increased fuel consumption and

Observing frost on LPG and regulators
is common during operation and normally is not
an indication of a problem. As LPG vaporizes and
travels from the tank to the generator engine it
expands. The amount of frost that forms can be
affected by the size of the cylinder, the amount
of fuel being used, the humidity of the air and other
operating conditions. In unusual situations this
frost may eventually restrict the flow of LPG gas
cylinders
NOTE:
to the generator resulting in deteriorating
performance. For example, if the tank temperature
is reduced to a very low level then the rate at which
the LPG vaporizes is also reduced and may not
provide sufficient fuel flow to the engine. This is
not an indication of a problem with the generator
but only a problem with the flow of gas from the
LPG cylinder. If generator performance seems
to be deteriorating at the same time that ice
formation is observed on tank valve, hose or
regulator then some actions may be taken to
eliminate this symptom. In these rare situations
it can be helpful to reduce or eliminate the cold
fuel system effects by doing one of the following:
The LPG cylinder can be temporarily warmed
by pouring warm water over the top of the
cylinder.
Exchanging fuel tanks to allow the first tank
to warm up, repeating as necessary
•
Placing the LPG cylinder at the end of the
generator near the handle, where engine fan
air flows out from the generator. This air is
slightly heated by flowing over the engine.

Charging The Generator Battery
WARNING
WARNING
SERVICE AND STORAGE
Infrequent Service
If the unit is used infrequently, difficult starting
may result. To eliminate hard starting, follow
these instructions:
1. Run the generator at least 30 minutes every
month.
2. Run the generator, then close the fuel shut-off
valve and allow the unit to run until the engine
stops.
3. Move the engine switch to the "OFF" position.
Long Term Storage
It is important to prevent gum deposits from forming
in essential fuel system parts such as the carburetor,
fuel hoses or tank during storage. Also, experience
indicates that alcohol-blended fuels (called gasohol,
ethanol or methanol) can 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 not being operated, or
is being stored more than one month, follow these
instructions to avoid engine problems:
1-ADD a properly formulated commercially FUEL
STABILIZER to the tank if it is not already added.
2-Operate the engine for 5-10 minutes to circulate
treated fuel into fuel lines and carburetor before
shutdown.
3- After engine cools down, remove all gasoline
from the fuel tank. Use a commercially available,
non-conductive vacuum siphon.

DANGER
Drain fuel into approved container outdoors,
away from open flame. Be sure engine is cool.
Do not smoke.
4-FUEL STARVATION: Turn fuel selector switch
to “GAS” position. Start and run the generator until it
stops from lack of gasoline. This will dry out all
remaining gasoline in tank, fuel lines and carburetor.
5-Turn fuel selector switch to “OFF” position.
Fully close the LPG cylinder knob if it is open and
disconnect LPG cylinder from the generator.
6-Allow the unit to cool entirely before cleaning
and storage.
7-Change oil with recommended grade oil.
8-Remove spark plug and pour about one teaspoon
of engine oil through the spark plug hole, then pull
the recoil starter several times to distribute the oil for
lubricating the cylinder. Reattach the spark plug.
Pull recoil slowly until resistance is felt. This will
close the valves so moisture cannot enter engine
9-Cover the unit and store in a clean, dry place
out of direct sunlight. NEVER USE WATER TO
CLEAN GENERATOR.
cylinder. Gently release recoil starter.
We recommend always using a fuel stabilizer.
A FUEL STABLIZER will minimize the formulation
of fuel gum deposits during storage, the fuel
stabilizer can be added to the gasoline in the
fuel tank, or into the gasoline in a storage
container.
Note:
•
If it is not practical to empty the fuel tank and
the unit is to be stored for some time, use a
commercially available FUEL STABILIZER added
to the gasoline to increase the life of the gasoline.
Run the unit for 5-10 minutes to circulate treated
gasoline into the fuel lines abs carburetor before
shutdown. DO NOT STORE GENERATOR WITHOUT
FUEL STABILIZER IN FUEL SYSTEM INCLUDING
TANK, FUEL LINES AND CARBURETOR.

Any damages or hazards caused by using
improper fuel, improperly stored fuel, and/
or improperly formulated stabilizers, are not

covered by manufacturer's warranty.
•
WARNING
Generator exhaust contains odorless and
colorless carbon monoxide gas.
To avoid accidental or unintended ignition of
your generator during periods of storage, the
following precautions should be followed:
When storing the generator for short or extended
periods of time make sure that the fuel selector
switch is in the “OFF” position and the battery
leads have been disconnected from the battery.
The battery powers up the starter motor and the
control module in this generator. This product is
equipped with an automatic battery charging circuit.
The battery will receive charging voltage when the
engine is running. The battery will maintain a proper
charge if the unit 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 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 on “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.
