Long term storage
If the machine will not be started for 30 days of longer, maintain and
store the machine as follows:
1. Remove debris from the machine. Check the machine for
damage and loose screws. Correct any problems so that the
machine can be restarted later without a problem.
2. Drain the fuel from the fuel tank. Start the engine and run it
until no fuel remains in the carburetor. (The engine will stop
automatically when no fuel remains.)
3. Allow the engine to cool. Remove the spark plug and squirt a
small amount of fresh engine oil into the spark plug hole. Slowly
pull the recoil starter cord two or three times.
4. Reinstall the spark plug. Slowly pull the recoil starter cord and
release it when you feel resistance. (This closes the intake and
exhaust ports.)
5. Lightly wipe the external surface of the engine with cloth. Then,
store the machine in a dry dust-free location where no open fire
is present.
6. Remove debris from the cutting blades. Check the cutting
blades for irregularities. To prevent rusting, apply oil sparingly
to the surface of the cutting blades and attach the blade cover
(standard accessory).
CAUTION
Do not store the machine for a prolonged period with fuel remaining
in the fuel tank. Impurities in the fuel will deteriorate, adversely
affecting the carburetor and fuel filter and possibly causing an
engine malfunction. Always fully drain the fuel before storing the
machine.
10. Adjusting the gap of the cutting blades
Four screws secure the lower cutting blade to the upper blade.
Adjust these screws to create sufficient gap between the upper and
lower cutting blades to allow the blades to reciprocate freely. If the
gap between the blades is insufficient, the cutting blades will not
reciprocate; if the gap is too great, the cutting blades will not cut
efficiently and will tend to become jammed with debris.
CAUTION
The cutting blades are very sharp. Wear heavy-duty
gloves and handle the blades with care. The cutting
blades are sharp and can cause injury.
Inspection timing - Before and after operation
1. Loosen the lock nut (O) (M6).
2. Tighten the screw (P) until no gap is present between the upper
and lower blades. Then back off the screw by 1/3 to 1/2 turn.
3. With the screw (P) held in position, tighten the lock nut (O) (M6).
4. Confirm that you can turn the flat washer (Q) with your finger.

11. Relubricating the cutting blades
If under-lubricated, the cutting blades will wear prematurely.
Inspection timing - Before operation
Before starting the work, relubricate the cutting blades
with oil.
NOTICE
Even before completing work, relubricate the cutting blades when
refueling or when taking a break. Frequent relubrication will help
extend the service life of the cutting blades.
