STORAGE
STORAGE PREPARATION
Proper storage preparation is essential for keeping your generator
trouble free and looking good. The following steps will help to keep
rust and corrosion from impairing your generator’s function and
appearance, and will make the engine easier to start when you use the
generator again.
Cleaning
Wipe the generator with a moist cloth. After the generator has dried,
touch up any damaged paint, and coat other areas that may rust with a
light film of oil.
Fuel
Depending on the region where you operate your equipment, fuel
formulations may deteriorate and oxidize rapidly. Fuel deterioration and
oxidation can occur in as little as 30 days and may cause damage to
the carburetor and/or fuel system. Please check with your authorised
Honda servicing dealer for local storage recommendations.
Gasoline will oxidize and deteriorate in storage. Old gasoline will cause
hard starting, and it leaves gum deposits that clog the fuel system. If
the gasoline in your generator deteriorates during storage, you may
need to have the carburetor and other fuel system components
serviced or replaced.
The length of time that gasoline can be left in your fuel tank and
carburetor without causing functional problems will vary with such
factors as gasoline blend, your storage temperatures, and whether the
fuel tank is partially or completely filled. The air in a partially filled fuel
tank promotes fuel deterioration. Very warm storage temperatures
accelerate fuel deterioration. Fuel deterioration problems may occur
after 30 days from keeping the fuel in the fuel tank, or even less
depending on the gasoline formulation in your area.

STORAGE
STORAGE PROCEDURE
1.Drain the fuel tank and carburetor.
Gasoline is highly flammable and explosive.
You can be burned or seriously injured when
handling fuel.
• Stop the engine and keep heat, sparks,
and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.
a. Unscrew the fuel tank cap and remove the fuel filter.
b. Drain all gasoline from the fuel tank into an approved gasoline
container. We recommend using a commercially available gasoline
hand pump. Do not use an electric pump.

4.Pour a teaspoon (5 cm
) of clean engine oil into the cylinder.
5.Pull the starter rope several times to distribute the oil in the cylinder.
6.Reinstall the spark plug (see page 40).
7.Reinstall the rear cover (see page 40).
8.Slowly pull the starter grip until resistance is felt. At this point, the
piston is coming up on its compression stroke and both the intake
and exhaust valves are closed. Storing the engine in this position
will help to protect it from internal corrosion. Return the starter grip
gently.

STORAGE
STORAGE PRECAUTIONS
If your generator will be stored with gasoline in the fuel tank and
carburetor, it is important to reduce the hazard of gasoline vapor
ignition.
Select a well-ventilated storage area away from any appliance that
operates with a flame, such as a furnace, water heater, or clothes dryer.
Also avoid any area with a spark-producing electric motor, or where
power tools are operated.
If possible, avoid storage areas with high humidity, because that
promotes rust and corrosion.
Unless all fuel has been drained from the fuel tank, leave the fuel valve
in the OFF position to reduce the possibility of leakage.
Place the generator on a level surface. Tilting can cause fuel or oil
leakage.
With the engine and exhaust system cool, cover the generator to keep
out dust. A hot engine and exhaust system can ignite or melt some
materials.
Do not use sheet plastic as a dust cover. A nonporous cover will trap
moisture around the generator, promoting rust and corrosion.
REMOVAL FROM STORAGE
Check your generator as described in the BEFORE OPERATION chapter
of this manual (see page 17).
If the fuel was drained during storage preparation, fill the tank with
fresh gasoline. If you keep a container of gasoline for refueling, be sure
that it contains only fresh gasoline. Gasoline oxidizes and deteriorates
over time, causing hard starting.
If the cylinder was coated with oil during storage preparation, the
engine may smoke briefly at startup. This is normal.

TRANSPORTING
BEFORE TRANSPORTING
1.Make sure the engine switch, fuel valve are OFF (see page 22).
2.Drain all gasoline from the fuel tank, tighten the fuel tank cap
securely (see page 42).
Gasoline is highly flammable and explosive.
You can be burned or seriously injured when
handling fuel.
• Stop the engine and keep heat, sparks,
and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.
WHEN TRANSPORTING THE GENERATOR
If the generator has been running, allow the engine to cool down
before loading the generator on the vehicle.
A hot engine and exhaust system can burn you and can ignite some
materials.
Do not load the generator on a vehicle to transport with the fuel filled.
The fuel may leak due to vibration during transport.
When transporting the generator, turn the engine switch and the fuel
valve lever OFF, and Keep the generator level to reduce the possibility
of fuel leakage.
Avoid a place exposed to direct sunlight when putting the generator on
a vehicle. If the generator is left in an enclosed vehicle for many hours,
high temperature inside the vehicle could cause fuel to vaporize
resulting in a possible explosion.
Do not drive on a rough road for an extended period with the generator
on board.
45
TRANSPORTING
Transporting the Generator by Truck
Load the generator on a place where it will not drop off, tumble over or
be damaged and tie it up with ropes or tie down straps.
When using ropes or tie down straps to secure the generator for
transportation, only use the frame bars as attachment points, by
protecting them with protective cloths or equivalent.
Do not fasten ropes or straps to any other portions of the generator
body.

TECHNICAL INFORMATION
CARBURETOR MODIFICATION FOR HIGH ALTITUDE OPERATION
At high altitude, the standard carburetor air fuel mixture will be too
rich. Performance will decrease, and fuel consumption will increase. A
very rich mixture will also foul the spark plug and cause hard starting.
Operation at an altitude that differs from that at which this engine was
certified, for extended periods of time, may increase emissions.
High altitude performance can be improved by specific modifications to
the carburetor. If you always operate your generator at altitudes above
1,500 meters, have your authorized Honda servicing dealer perform
this carburetor modification.
Even with carburetor modification, engine horsepower will decrease
about 3.5% for each 300 meter increase in altitude. The effect of
altitude on horsepower will be greater than this if no carburetor
modification is made.
When the carburetor has been modified for high altitude operation, the
air/fuel mixture will be too lean for low altitude use. Operation at
altitudes below 1,500 meters with a modified carburetor may cause
the engine to overheat and result in serious engine damage. For use at
low altitudes, have your authorised Honda servicing dealer return the
carburetor to original factory specifications.
