Note: – If the starter knob is pulled repeatedly when the choke button 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 knob slowly to remove excess fuel. Also, dry the
electrode section of the spark plug.
Caution during operation:
If the control lever is opened fully in a no-load operation, the engine rotation is increased to 10,000 rpm 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
– As described above, except without moving the choke button.
Stopping
– Release the throttle lever (6) 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.
NYLON CUTTING HEAD
Operation
– Increase the nylon cutting head speed to approx. 6,000 / min.
Low speed (under 4,800 / min) is not suitable, the nylon cord will not feed
out properly at low speed.
– The most effective cutting area is shown by the shaded area.
IDLE ADJUSTMENT
Checking the Idling speed
– Idle speed should be set to 3,000 / min.
If necessary correct it by means of the idle screw (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.
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.
The nylon cutting head is a dual string trimmer head capable of bump & feed mechanisms.
The nylon cutting head will automatically feed out the proper length of nylon cord by the changes in centrifugal force caused by increasing
or decreasing RPMS. However, to cut soft grass more efficiently, bump the nylon cutting head against the ground to feed out extra cord as
indicated under operation section.
