Drain 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 materials remaining in the fuel tank, remove it completely.
2) Pull out the fuel filter from the refill port using a wire.
3) Push the primer pump until fuel is drained from there, and drain fuel coming into
the fuel tank.
4) Reset the filter to the fuel tank, and securely tighten the fuel tank cap.
5) Then, continue to operate the engine until it stops.

-
plug hole.
Gently pull the starter handle so that engine oil will spread over the engine, and
-
attach the spark plug.
Attach the cover to the cutting blades.
-
During storage, keep the rod horizontal or keep the machine upright with the
-
blade edge oriented upward. (In this case, pay full attention to prevent the
machine from falling.)
Never store the machine with the cutting blade edge oriented downward.
-
Lubricating oil may spill out.
Keep the drained fuel in a special container in a well-ventilated shade.
-
WARNING: When draining the fuel, stop the engine and wait for the engine to cool down.
Failure to do so may cause burns or fire.
ATTENTION: When you store the machine for a long time, drain all fuel from the fuel tank and carburetor, and keep it at a dry and
clean place.
