Checking the Idling speed
Idle speed should be set to 3,000 min
–
-1
.
If necessary correct it by means of the idle screw (the blade or the nylon
cutting head must not turn when the engine is on idle).
Screwing in the screw (1) will cause an increase in the engine speed,
whereas backing off the screw will reduce the engine speed.
STOPPING
Release the throttle lever (4) fully, and when the engine rpm has lowered,
–
push the I-O switch (1) to “O” position the engine will now stop.
Be aware that the cutting head may not stop immediately and allow it to slow
–
down fully.
Run the engine for approximately one minute at a moderate speed before applying full throttle.
–
Note: – If the starter handle is pulled repeatedly when the choke lever remains at “
” position, the engine will not start easily due to excessive
fuel intake.
– In case of excessive fuel intake, remove the spark plug and pull the starter handle slowly to remove excess fuel. Also, dry the
electrode section of the spark plug.
Caution during operation:
If the throttle lever is opened fully in a no-load operation, the engine rotation is increased to 10,000 min
-1
or more. Never operate the engine at a
higher speed than required and at an approximate speed of 6,000 - 8,000 min
-1
.
Starting the warm engine
Same as above, except without moving the choke lever (choke lever remains in the position “
–
”).
ADJUSTMENT OF LOW-SPEED ROTATION (IDLING)
The cutter blade or the nylon cutting head should not run when the control lever is fully released. If necessary, adjust the idle rpm using the idle
adjusting screw.
CAUTION: The cutting tools mentioned below must only be resharpened by an
authorized facility. Manual resharpening will result in imbalances of
the cutting tool causing vibrations and damage to the equipment.

–
An expert resharpening and balancing service is provided by Authorized Service
Agents.
NOTE: To increase the service life of the cutter blade (star blade) it may be
turned over once, until both cutting edges have become blunt.
