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,
inammability and re.
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 lter from the rell port using a wire.
3) Push the primer pump until fuel is drained from there, and drain fuel coming into the fuel tank.
4) Put the lter to the fuel tank, and securely tighten the fuel tank cap.
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.)
Never store the machine with the cutting attachment side oriented downward. Lubricating oil may spill out.
Keep the drained fuel in a special container in a well-ventilated shade. –
Attention after long-time storage
Before startup after long-time shutdown, be sure to replace oil (refer to P 14). Oil will deteriorate while the machine is kept out of –
