3.7 VALVE CLEARANCE
• Intake — 0.15 ± 0.02mm (cold), (0.006" ± 0.0008")
• Exhaust — 0.20 ± 0.02mm (cold) (0.008" ± 0.0008")
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 ensure longest life for the engine.
3.8 GENERAL
The generator should be started at least once every 30 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.
Allow unit to cool entirely before storage.

3.9 LONG TERM STORAGE
1. Drain oil from crankcase after the engine cools down. Refill
with recommended grade.
2. Remove spark plug and pour about 1/2 ounce (15 ml) of
engine oil into the cylinder. Cover spark plug hole with rag. Pull
the recoil starter a couple times to lubricate the piston rings
and cylinder bore. A commercial fogging agent can be used in
place of oil.
Avoid spray from spark plug hole when
cranking engine.
3. Install and tighten spark plug. Do not connect spark plug wire.
4. Clean the generator outer surfaces. Check that cooling air
slots and openings on generator are open and unobstructed.
5. Store the unit in a clean, dry place.
3.10 OTHER STORAGE TIPS
• If possible, store the unit indoors and cover it to give protection
from dust and dirt. BE SURE TO CLOSE THE VALVE ON THE
FUEL TANK.
• Cover the unit with a suitable protective cover that does not
retain moisture.
NEVER cover the generator while engine and
exhaust areas are warm.
