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