STORAGE

When the machine is kept out of operation for a long time, perform the
followings:
- Drain up 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.
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.
- Drain up the chain oil.
- Remove the saw chain and the guide bar.
- Clean the guide groove of the guide bar.
- Lubricate slightly on the saw chain and the guide bar.
- 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.
- In general, store the machine in horizontal position. If it is not possible,
place the machine as the motor unit comes below the cutting tool. Otherwise
engine oil may leak from inside.
- Always pay attention to storing the machine in a safe place to prevent
machine damage and personal injury.
