Long Term Storage

Whenever the unit will not be used for 30 days or longer, use the following proce- dures to prepare it for storage:

■■Clean external parts thoroughly and apply a light coating of oil to all metal surfaces.

■■Drain all the fuel from the carburetor and the fuel tank.

To do so:

1.Prime the primer bulb until no more fuel is passing through.

2.Start and run the engine until it stops running.

3.Repeat steps 1 and 2 until the engine will no longer start.

CAUTION!

Gasoline stored in the carburetor for extended periods can cause hard starting, and could also lead to increased service and maintenance costs.

IMPORTANT!

All stored fuels should be stabilized with a fuel stabilizer such as STA-BIL™.

NOTE:

Damage resulting from stale or contami- nated fuel is not covered by the Shindaiwa warranty policy.

■■Remove the spark plug and pour about 1/4 oz. of engine oil into the cylinder through the spark plug hole. Slowly pull the recoil starter 2 or

3 times so oil will evenly coat the interior of the engine. Reinstall the spark plug.

■■Before storing the unit, repair or replace any worn or damaged parts.

■■Remove the air cleaner element from the carburetor and clean it thor- oughly with soap and water. Let dry and reassemble the element.

■■Store the unit in a clean, dust-free area.
