STORAGE
– When storing the equipment for a long period of time, drain all the fuel from
the fuel tank and carburetor. To do this, simple drain all of the fuel from the
fuel tank. Dispose of the drained fuel in accordance with local applicable
laws.
– Remove the spark plug and add a few drops of oil into the spark plug hole.
Then, pull the starter gently so that oil coats the inside of the engine, then
tighten the spark plug.
– Clean any dirt or dust from the cutter blade and outside of the engine, and
wipe them with a oil-immersed cloth. Store the equipment in a dry place.
