STOPPING
–Release the throttle lever fully, and when the engine rpm has lowered, push the
–Be aware that the cutting head may not stop immediately and allow it to slow down fully.
ADJUSTMENT OF LOW-SPEED ROTATION (IDLING)
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 | (1) |
–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.

NYLON CUTTING HEAD
The nylon cutting head is a dual string trimmer head capable of both automatic and 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.
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.
If the nylon cord does not feed out automatically proceed as follows:
1.Release the control lever to run the engine idle and then squeeze the control lever fully. Repeat this procedure until the nylon cord feeds out to the proper length.
2.If the nylon cord is too short to feed out automatically with the above procedure, bump the knob of the nylon cutting head against the ground to feed out the nylon cord.
3.If the nylon cord does not feed out with procedure 2, rewind/replace the nylon cord by following the procedures described under “Replacing the nylon cord”.
