STORAGE

If the pole hedge trimmer is to be stored for an extended period of time, proceed
as follows:
- Drain all fuel from the tank and carburetor.
- Remove the spark plug and add a few drops of two-stroke oil through the spark
plug hole. Gently pull out the starter rope to ensure that the oil is evenly
distributed inside the engine. Replace and tighten the spark plug.
- Clean the entire pole hedge trimmer and apply a thin layer of oil to the metallic
surfaces of the machine. Secure and protect the blades with the blade cover
provided. Store the pole hedge trimmer in location that is free of humidity.
