RESHARPENING THE CUTTING TOOL

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.
– cutter blade (star blade (4 teeth), eddy blade (8 teeth))
An expert resharpening and balancing service is provided by Authorized
Service Agents.
NOTE: To increase the service life of the cutter blade (star blade, eddy blade) it
may be turned over once, until both cutting edges have become blunt.

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. 6,000rpm.
Low speed (under 4,800rpm) 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 throttle lever to run the engine idle and then squeeze the throttle
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".
Replacing the nylon cord
– First, stop the engine.
– Press on the housing latches inward to lift off the cover, then remove the
spool.
– Hook the center of new nylon cord into the notch in the center of the spool,
with one end of the cord extending about 80mm (3-1/8") more than the other.
Then wind both ends firmly around the spool in the direction of the head
rotation (left-hand direction indicated by LH and right-hand direction by RH on
the side of the spool).
