Nylon Cutting Head - Dolmar LT-210 Original Instruction Manual

STOPPING
– Release the throttle lever 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.
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
– 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 4,800min
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".
