WARNING: When draining the fuel, be sure to stop the engine and make sure that the engine

cools down.

Just after stopping the engine, it may still be hot with possibility of burns,

inﬂammability and ﬁre.

ATTENTION: When the machine is kept out of operation for a long time, drain up all fuel from the

fuel tank and carburetor, and keep it at a dry and clean place.

Drain fuel from the fuel tank and carburetor according to the following procedure: –

1) Remove the fuel tank cap, and drain fuel completely.

If there is any foreign matter remaining in the fuel tank, remove it completely.

2) Pull out the fuel ﬁlter from the reﬁll port using a wire.

3) Push the primer pump until fuel is drained from there, and drain fuel coming into the fuel tank.

5) Then, continue to operate the engine until it stops.

Remove the spark plug, and drip several drops of engine oil through the spark plug hole. –

Gently pull the starter handle so that engine oil will spread over the engine, and attach the spark plug. –

During storage, keep the rod horizontal or keep the machine upright with the cutting attachment side oriented upward. (In this case, pay full –

attention to prevent the machine from falling.)

Keep the drained fuel in a special container in a well-ventilated shade. –
