STORAGE

– When the machine is in storage for a long time, drain fuel from the fuel tank

and carburetor, as follows: Drain all fuel from the fuel tank. Dispose of

properly and in accordance with all local laws.

– Remove the spark plug and a few drops of oil into the spark plug hole.

Then, pull the starter gently, so that oil covers the engine inside and tighten

the spark plug.

– Clear dirt or dust from the nylon cutting head and outside of engine, wipe

them with a oil-immersed cloth and keep the machine in a place as dry as

possible.
