Kickback prevention
To avoid kickbacks, observe the following:
~ Operation within a blade segment between 12 and 2 o'clock presents positive
hazards, especially when using metal cutting tools.
~ Culling operations within a blade segment between 11 and 12 o'clock, and
between 2 and 5 o'clock, must only be performed by trained and experienced
operators, and then only at their own risk. Easy cutting with almost no kickback is
possible within a blade segment between 8 and 11 o'clock.
Cutting Tools
Employ only the correct cutting toot for the job in hand.
Nylon cutting head:
Exclusively designed for cutting along walls, fences, grass edges, trees, posts
etc. (supplementing the grass mower). Perform this cutting work by swinging
the grass trimmer evenly in half-circles from left to right.
Metal blade (Star Blade (4 teeth), Eddy Blade (8 teeth):
For cutting thick materials, such as weed, high grass, bushes, shrubs,
underwood, thicket etc. (max. 2 cm dia, thickness). Perform this cutting work
by swinging the brush cutter evenly in half-circles from right to left (similar to
using a scythe),

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.
Most effective cutting 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 throtlle 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. 7 mo (0
