Intake — 0.15 ± 0.02mm (cold), (0.006" ± 0.0008" inches)
Exhaust — 0.20 ± 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 ensure longest life for the engine.
The generator should be started at least once every thirty 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.
Allow unit to cool entirely before 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
To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer, as follows:
A quality fuel stabilizer should be added to the existing fuel per the manufacturers specifications.
Drain fuel into approved container outdoors, away from open flame. Be sure engine is cool. Do not smoke.
Maintenance
Start and run the engine for 10 - 15 minutes, after that time and while the unit is running, turn the fuel
Allow the engine to cool, then remove all gasoline from the fuel tank. Use a commercially available,
Remove spark plug and spray with a quality fogging agent, or 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.
Avoid spray from spark plug hole when cranking engine.
Install and tighten spark plug. Do not connect spark plug wire.
Clean the generator's outer surfaces. Check that cooling air slots and openings on generator are open and unobstructed.
Store the unit in a clean, dry place.
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. Start and run the engine for 10 - 15 minutes, after that time and while the unit is running, turn the fuel
Cover the unit with a suitable protective cover that does not retain moisture.
NEVER cover the generator while engine and exhaust area are warm.
