MAINTENANCE EVERY 100 HOURS

1. Remove the muffler, insert a

screwdriver into the vent, and wipe
off any carbon. Also, wipe off any
carbon at the muffler outlet.

(1) Screwdriver
(2) Muffler

2. Further tighten all screws, bolts

and fittings.

3. Make sure that no oil or grease

remains between the clutch lining
and the drum. If you see any
there, wipe it off using oil-free,
lead-free gasoline.

ADJUSTING THE ENGINE

Continued rotation of the blade
after the throttle lever is set to the
idling position could be
dangerous. If the blade continues
to rotate even after readjusting the
idling adjustment screw, the
throttle lever, throttle wire, or
clutch might be faulty. Contact the
shop where you bought this
product, and ask it to check and
repair the trouble.

• The idling engine speed is

adjusted when this product is
shipped from the factory, but it
might need to be readjusted
according to changes in operation
conditions (e.g. changes in the
stability of the engine, air density,
etc.). When readjustment is
necessary, try to do so as
described below. If this is difficult,
contact the shop where you
bought this product, and ask it to
implement the readjustment.

• Make sure the throttle wire is

parallel with the flexible shaft. If
the throttle wire is twisted,
straighten it.

• If the flexible shaft is bent, the play

of the throttle wire changes. When
you adjust the idling, bend the
flexible shaft and adjust the idling
in a standing position similar to the
position in which you actually use
the machine.
