Fueling
WARNING
○ Always shut off the engine before refueling.
○ Slowly open the fuel tank, when fi lling up with fuel, so that
possible over-pressure disappears.
○ Tighten the fuel cap carefully, after fueling.
○ Always move the brush cutter at least 3 m from the fueling area
before starting.
○ Always wash any spilled fuel from clothing immediately with
soap.
○ Be sure to check for any fuel leakage after refueling.
Before fueling, clean the tank cap area carefully, to ensure that
no dirt falls into the tank. Make sure that the fuel is well mixed by
shaking the container, before fueling.
Starting (Fig. 16)
CAUTION
Before starting, make sure the cutting attachment does not
touch anything.
1. Slide ignition switch (13) to RUN position. (Fig. 16)
* Push priming bulb (16) several times so that fuel fl ows through
return pipe. (Fig. 17)
2. With the safety trigger (14) (if so equipped) pressed, pull
throttle trigger and push throttle lock (15). Then slowly release
the throttle trigger fi rst, then the safety trigger. This will lock the
throttle in starting position.
3. Set choke lever to CLOSED position (17). (Fig. 18)
4. Pull recoil starter briskly, taking care to keep the handle in your
grasp and not allowing it to snap back. (Fig. 19)
5. When you hear the engine want to start, return choke lever to
RUN position (open). Then pull recoil starter briskly again.
NOTE
If engine does not start, repeat procedures from 2 to 5.
6. After starting engine, pull throttle trigger to release throttle lock.
Then allow the engine about 2–3 minutes to warm up before
subjecting it to any load.
Cutting (Fig. 20, 21, 22)
○ When cutting, operate engine at over 6500 rpm. Extended time
of use at low rpm may wear out the clutch prematurely.
○ Cut grass from right to left.
○ Blade thrust may occur when the spinning blade contacts a
solid object in the critical area.
A dangerous reaction may occur causing the entire unit and
operator to be thrust violently. This reaction is called blade
thrust. As a result, the operator may lose control of the unit
which may cause serious or fatal injury. Blade thrust is more
likely to occur in areas where it is diffi cult to see the material to
be cut.
○ Wear the harness as shown in the fi gure. The blade turns
counter-clockwise, therefore, be advised to operate the unit
from right to left for effi cient cutting. Keep onlookers out of
working area at least 15 m.
NOTE
Press the quick release button or pull emergency release fl ap in
the event of emergency. (Fig. 23)
How to use the shoulder harness
Wear the shoulder harness on your shoulder as shown Fig. 21
and hook it on the hanger of the machine. Adjust the length of the
shoulder harness to the most comfortable position. (Fig. 21)
To remove the machine from the shoulder harness, hold the main
pipe of the machine fi rmly by one hand and then remove the hook
(19) of the shoulder harness from the hanger (20). (Fig. 23-a)
How to reinstall the hook after using the emergency release
pinch
It needs to go through the buckle (21) of the hook (19) to the metal
plate (22) on the harness and go through the plate (23) of the
emergency release pinch to the metal plate (22) on the harness.
(Fig. 23-b)
After installing the buckle onto the harness, pull the hook (19) and
make sure the hook (19) is securely fi xed on the harness, then hook
it to the hanger (20). (Fig. 23-a)
WARNING
○ When using the machine, wear the shoulder harness and hold
the machine correctly with both hands.
If you feel that there is something dangerous, separate the
brush cutter from your body by pulling the emergency release
pinch (18) of the harness to the direction of the arrow shown in
Fig. 23-a.
○ If the cutting attachment should strike stones or other debris,
stop the engine and make sure that the attachment and related
parts are undamaged. When grass or vines wrap around
attachment, stop engine and attachment and remove them.
NOTE
If you pull the emergency release pinch without holding the
machine, the machine will fall to your feet. Pull the emergency
release pinch while holding the main pipe of the machine by
one hand.
Before operation, make sure that the emergency release pinch
on the shoulder harness is working properly.
Stopping (Fig. 24)
Decrease engine speed and run at an idle for a few minutes, then
turn off ignition switch (13).
WARNING
A cutting attachment can injure while it continues to spin after
the engine is stopped or power control is released. When the
unit is turned off , make sure the cutting attachment has stopped
before the unit is set down.
How to use nylon head
When cutting, operate engine at over 6500 rpm. Extended use at
low rpm may wear out the clutch prematurely.
This product is designed so that it will stop cutting when the nylon
line becomes 16 cm or longer.
WARNING
A cutting attachment can injure while it continues to spin after the
engine is stopped or power control is released. When the unit is
turned off , make sure the cutting attachment has stopped before
the unit is set down.
Set the engine speed as low as possible and tap the Head on the
ground. (Fig. 25) Also, you can extend nylon line with hands but the
engine must be completely stopped. (Fig. 26)
Adjust nylon line to proper length 11 – 14 cm before each operation.
