Valve Clearance
Important: Please contact an Independent
Authorized Service Dealer for service assis -
tance. Proper valve clearance is essential for
prolonging the life of the engine.
Check valve clearance after the first fifty-hours
of operation. Adjust as necessary.
• Intake — 0.1 ± 0.02mm (cold), (0.004" ±
0.001" inches)
• Exhaust — 0.15 ± 0.02mm (cold) (0.006" ±
0.001" inches)
Storage
General
It is recommended to start and run the genera -
tor for 30 minutes, every 30 days. If this is not
possible, refer to the following list to prepare
unit for storage.
• DO NOT place a storage cover on a hot
generator. Allow unit to cool to room tem -
perature before storage.
• DO NOT store fuel from one season to
another unless properly treated.
• Replace fuel container if rust is present.
Rust in fuel will cause fuel system prob -
lems.
• Cover unit with a suitable protective, mois -
ture resistant cover.
• Store unit in a clean and dry area.
• Always store generator and fuel away from
heat and ignition sources.
Prepare Fuel System for Storage
Fuel stored over 30 days can go bad and
damage fuel system components. Keep fuel
fresh, use fuel stabilizer.
If fuel stabilizer is added to fuel system, pre -
pare and run engine for long term storage.
Run engine for 10-15 minutes to circulate sta -
bilizer throughout fuel system. Adequately
prepared fuel can be stored up to 24 months.
NOTE: If fuel has not been treated with fuel
stabilizer, it must be drained into an approved
container. Run engine until it stops from lack
of fuel. Use of fuel stabilizer in fuel storage
container is recommended to keep fuel fresh.
1. Change engine oil.
2. Remove spark plug.
3. Pour tablespoon (5-10cc) of clean engine
oil or spray a suitable fogging agent into
cylinder.
4. Pull starter recoil several times to distrib -
ute oil in cylinder.
5. Install spark plug.
6. Pull recoil slowly until resistance is felt.
This will close valves so moisture cannot
enter engine cylinder. Gently release
recoil.
