Generac 005789-0 Benutzerhandbuch

Intake — 0.10 ± 0.02mm (cold), (0.003" ± 0.005" inches)

• 

Exhaust — 0.15 ± 0.02mm (cold) (0.005" ± 0.007" 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 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.



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.

• 

 

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.



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.

• 

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.
