EQUIPPING THE SHAWL BAND(F12)
1. Equip the attached shawl band.(F12)
2. Turn on the engine, return the throttle lever to the lowest speed
position, and put the shawl band hook to the hanging part of the machine.
3. djust the length of the shawl band so that the blade is parallel to
the ground in the working position. In order to prevent slack during operation, turn up the extra part of
the band from the buckle.
CUTTING OPERATION
METAL BLADE USAGE
lways cut by guiding the head from your right to left.
 metal blade cuts best with the outer 1/3. Use that area for
cutting shrubs, plus tough and thick weeds. For cutting young
grass you can use the outer 2/3 of the blade.
djust the engine speed according to what you are cutting. Cut
young grass at middle speed. Cut shrubs or tough and thick
weeds at high speed.
(1) For branches and trees
(2) For grass and weeds
(3) Direction of cutting
(4) Direction of rotation
Operating at low speed makes it easier for grass, weeds or twigs to
become caught up in the blades. nd also it makes the shaft and
clutch wear down more quickly.
NYLON CUTTER USAGE
Using nylon cord consumes more power. Please note that the engine rotation speed in operation should be
50% more than when using the metal blade. The nylon cutter cuts grass with the power of cord rotation. If
you try to cut grass with the same length of cord for any time, rotation speed becomes lower due to
resistance and you cannot cut well. In case of high resistance, remove the nylon cutter from grass, increase
the rotation speed and cut a small amount of grass at one time.
If you try to cut grass by swinging the brush cutter in the reverse way (from left to right), cut pieces fly in
from the body. You can avoid getting your clothes dirty.
