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:

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

nDrain all the fuel from the carburetor and the fuel tank.

IMPORTANT!

All stored fuels should be stabilized with a fuel stabilizer such as STA-BIL™, if oil with fuel stabilizer is not used.

Remove the remaining fuel from the fuel lines and carburetor. With the fuel drained from the fuel tank:

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 carbure- tor for extended periods can cause hard starting, and could also lead to increased service and maintenance costs.

nRemove the spark plug and pour about 7.4 ml of 2-cycle mixing 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.

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

nRemove the air cleaner element from the carburetor and clean it thoroughly with soap and water. Let dry and reassemble the element.

nStore the unit in a clean, dust-free area.
