STOPPING
– Release the throttle lever (6) fully, and when the engine rpm has lowered,
push the I-O switch (1) to “O”
㩷
position the engine will now stop.
– Be aware that the cutting head may not stop immediately and allow it to slow
down fully.
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.
Checking the Idling speed
– Idle speed should be set to 2,600 /min.
If necessary correct it by means of the idle screw (the cutting blade 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.
– 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 or more. Never operate the engine at a
higher speed than required and at an approximate speed of 6,000 - 8,000
/min.
Starting the warm engine
– Same as adove, except without moving the choke lever (choke lever remains in the position “ ” ).
– First place the machine on the ground.
– Give a gentle push on the primer pump (2) repeatedly (7-10 times) until fuel
comes into the primer pump.
– Push the choke lever (3) to the position “ ”.
(3)
(2)
– Firmly hold the clutch case by your left hand, as illustrated.
– Slowly pull the starter grip until resistance is felt and continue with a smart
pull.
– Do not pull out the starter rope to its full extent and do not allow the starter
handle to be retracted without control, but ensure that it is retracted slowly.
– Repeat the starting operation until initial ignitions are heard.
– When the engine start, return the choke lever to “ ”. Please note that the
choke lever will return to “ ”position automatically when the throttle lever is
operated and the throttle is opened.
