3.6 VALVE CLEARANCE
• Intake — 0.15 ± 0.02mm (cold), (0.006" ± 0.0008" inches)
• Exhaust — 0.2 ± 0.02mm (cold) (0.008" ± 0.0008" inches)
After the first 50 hours of operation, check the valve clearance
in the engine and adjust if necessary.
Important:
If feeling uncomfortable about doing this procedure or
the proper tools are not available, please take the generator to the
nearest service center to have the valve clearance adjusted. This is
a very important step to insure longest life for the engine.
3.7 GENERAL
The generator should be started at least once every seven days and
be allowed to run at least 30 minutes. If this cannot be done and
the unit must be stored for more than 30 days, use the following
information as a guide to prepare it for storage.

NEVER store engine with fuel in tank indoors or in
enclosed, poorly ventilated areas where fumes may reach
an open flame, spark or pilot light as on a furnace, water
heater, clothes dryer or other gas appliance.
3.8 LONG TERM STORAGE
It is important to prevent gum deposits from forming in essential
fuel system parts such as the carburetor, fuel hose 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.
To avoid engine problems, the fuel system should be emptied
before storage of 30 days or longer, as follows:
• Remove all gasoline from the fuel tank.

Drain fuel into approved container outdoors, away from
open flame. Be sure engine is cool. Do not smoke.
• Start and run engine until engine stops from lack of fuel.
• While engine is still warm, drain oil from crankcase. Refill with
recommended grade.
• Remove spark plugs and pour about 1/2 ounce (15 ml) of
engine oil into the cylinders. Cover spark plug hole with rag.
Pull the recoil starter a couple times to lubricate the piston rings
and cylinder bore.

Avoid spray from spark plug holes when cranking engine.
• Install and tighten spark plugs. Do not connect spark plug
wires.
• Clean the generator outer surfaces. Check that cooling air slots
and openings on generator are open and unobstructed.
• Store the unit in a clean, dry place.
3.9 OTHER STORAGE TIPS
• Do not store gasoline from one season to another.
• Replace the gasoline can if it starts to rust. Rust and/or dirt in
the gasoline will cause problems with the carburetor and fuel
system.
• If possible, store the unit indoors and cover it to give protection
from dust and dirt. BE SURE TO EMPTY THE FUEL TANK.
• 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.
• Cover the unit with a suitable protective cover that does not
retain moisture.

NEVER cover the generator while engine and exhaust
area are warm.
