■ STOPPING THE ENGINE
1. Release the throttle lever.
2. Move the engine switch to the "O" position.
■ LINE HEAD USAGE
1. Always wear eye protection such as
safety goggles. Never lean over the
rotating cutting head. Rocks or other
debris could be thrown into eyes and
face and cause serious personal injury.
2. Keep the debris guard attached in place
at all times when the unit is operated.
TRIMMING GRASS AND WEEDS
•
Always remember that the TIP of the line
does cutting. You will achieve better results
by not crowding the line into the cutting
area. Allow the unit to trim at its own pace.
1. Hold the unit so the head is off the ground
and is tilted about 20 degrees toward the
sweep direction.
2. Use full throttle when cutting.
3. You can avoid thrown debris by sweeping
from your left to the right.
4. Use a slow, deliberate action to cut heavy
growth. The rate of cutting motion will
depend on the material being cut. Heavy
growth will require slower action than will
light growth.
5. Never swing the unit so hard as you are in
danger of losing your balance or control of
the unit.
6. Try to control the cutting motion with the hip
rather than placing the full workload on the
arm and hands.
7. Take precautions to avoid wire, grass and
dead, dry, long-stem weeds from wrapping
around the head shaft. Such materials can
stall the head and cause the clutch to slip,
resulting in damage to the clutch system if
repeated frequently.
ADJUSTING THE LINE LENGTH
•
Your brushcutters is equipped with a semi-
auto type nylon line head that allows the
operator to advance the line without
WARNING
■ CUTTING WORK
• By using the shoulder strap, hang the unit
on your right side. Adjust the strap length so
that the cutting head may become parallel
to the ground.
• Choose a suitable recommended cutting
attachment according to the object to be
cut. Never use other cutting attachment not
approved by KOMATSU ZENOAH.
4. Place the unit on a flat, firm place. Keep the
cutting head clear of everything around it.
5. While holding the unit firmly, pull out the
starter rope quickly.
6. After the engine has started, open the
choke guradually and allow the engine to
warm up. Pull the throttle lever to unlock it.
■ ADJUSTMENTS
• Throttle cable: The normal play is 1 or 2 mm
when measured at the carburetor side end.
Readjust with the cable adjuster(1) as re-
quired.
• Engine idling speed: It is normal that the
engine keeps running without the blade
rotation, when the throttle lever is released.
When the engine speed is too high or too
slow, readjust the idle set screw (2).

■ REFILLING TRIMMING LINE
1. For replacement line, use a diameter of
.095in (2.4mm). The spool is capable for a
line upto 27ft (8m) on the 4” head, and 46ft
(14m) on the 6” head. Avoid using a larger
line as it may cut down the trimming
performance. For safety reasons, do not
use metal line.
2. Pinch the slotted area on the both sides of
the spool housing to unhook the bottom
cap. (F1)
3. Take out the spool and pull off the old line.
Put one end of new line through the spool
holes and pull it until the length is equal
between each part of the line. (F2)
4. Wind up the line in the correct as indicated
on the spool. (F3)
5. Hook each end of the line in the slot on the
edge of the spool, and then put the ends
through the eyelets on the housing. Make
sure that the spring and the washers are in
place. (F4)
6. While holding the spool against the housing,
pull the line ends to release them from the
slot.
7. Line up the slot on the bottom cap with the
hook on the housing, press the cap against
the housing until it clicks.
stopping the engine. When the line
becomes short, lightly tap the head on the
ground while running the engine at full
throttle.
• Each time the head is bumped, the line
advance about 1 inch(25.4 mm). For better
effect, tap the head on bear ground or hard
soil. Avoid bumping in thick, tall grass as
the engine may stall by overload.
Before cleaning, inspecting, or repairing
the unit, make sure that the engine has
stopped and is cool.
