Use in accordance with local laws and regulations.
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 (11) of the shoulder harness from the
hanger (12). (
Fig. 22-a
)
How to reinstall the hook after using the emergency
release pinch
It needs to go through the buckle (27) of the hook (11) to the
metal plate (28) on the harness and go through the plate (29)
of the emergency release pinch to the metal plate (28) on the
harness. (
Fig. 22-b
)
After installing the buckle onto the harness, pull the hook
(11) and make sure the hook (11) is securely
fi
xed on the
harness, then hook it to the hanger (12). (
Fig. 22-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 (26) of the harness to the direction of the
arrow shown in
Fig. 22-a
.
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.
(1) Using a semi-auto cutting head
○
Set the engine at high speed when using this attachment.
○
Cut grass from left to right. The cut grass will be
discharged away from the body, minimizing transfer to
your clothes. (
Fig. 23
)
○
With nylon cord, use about 2 cm of the end of the cord
to cut grass. Using the full length of the cord will reduce
rotation speed and make cutting di
ffi
cult.
NOTE
Automatically feeds more nylon cutting line when it is
tapped at low rpm (not greater than 4500 min
-1
).
WARNING
○
This product is equipped with a line limiter that will
automatically cut any excess cord. When operating the
unit, do not remove the guard or line limiter.
As the resistance is greater for nylon cords as opposed
to blades, mishandling could increase engine load and
result in damage.
○
Do not use with the engine set at low speeds. If the
engine speed is low, grass may wrap around the
attachment, causing the clutch to slip which could result
in clutch abrasion.
○
With nylon cord cutters, always use over 15 cm of cord.
If the length of the cord is too short, rotation speed will
increase and may cause damage to the nylon cord
cutter. As the curved drive shaft tube model in particular
is not equipped with a deceleration mechanism, the
possibility of increased rotation speed for the cutting
attachment is high.
(2) Using a blade
○
Adjust engine speed according to the resistance of the
grass. For soft grass, use low speeds, For tough clumps
of grass, use high speeds.
○
Cut grass from right to left, using the left side of the blade
to cut. (
Fig. 24
)
○
Slightly tilting the blade to the left while cutting will pile
the cut grass to the left, making collection easy.
NOTE
Excessively increasing rotation speed may cause
increased blade wear, vibration and noise. It will also
result in increased fuel consumption.
WARNING
○
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 di
ffi
cult
to see the material to be cut.
○
If cutting attachment should strike against stones or
other debris, stop the engine and make sure that the
attachment and related parts are undamaged.
Stopping (Fig. 25)
Decrease engine speed and run at an idle for a few minutes,
then turn o
ff
ignition switch (21).
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 o
ff
, make sure the cutting
attachment has stopped before the unit is set down.
MAINTENANCE
MAINTENANCE, REPLACEMENT OR REPAIR OF THE
EMISSION CONTROL DEVICES AND SYSTEMS MAY
BE PERFORMED BY ANY NON-ROAD ENGINE REPAIR
ESTABLISHMENT OR INDIVIDUAL.
Carburetor adjustment (Fig. 26)
The carburetor is a precision part that mixes air and fuel, and
it is designed to ensure high performance from the engine.
Before the tool is shipped from the factory, its carburetor is
adjusted during a test run. Only make adjustments if it is
necessary because of environmental conditions (the climate
or atmospheric pressure), the type of fuel, the type of two-
cycle oil, etc.
WARNING
○
Because the carburetor is manufactured with a high
degree of precision, do not disassemble it.
○
For this product, the only setting of the carburetor that
can be adjusted is the idle speed (T).
○
Never start the engine without the complete clutch cover
and tube assembled! Otherwise the clutch can come
loose and cause personal injuries.
T = Idle speed adjustment screw.
Idle speed adjustment (T)
WARNING
○
When the engine is stopped, do not excessively turn
the idle speed adjustment screw (T) in a clockwise
direction. Otherwise, when the engine starts, the cutting
attachment may unexpectedly rotate and cause an
injury.
○
Do not adjust the idle speed adjustment screw (T) for
any reason other than to adjust the idling.
