NOTE
○ Press the quick release button in the event of emergency.
(Fig. 24)
○ Use in accordance with local laws and regulations.
(1) 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. 25)
○ 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 diffi 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.
(2) Using a nylon 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. 26)
○ 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 diffi cult.
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.
Stopping (Fig. 27)
Decrease engine speed and run at an idle for a few minutes,
then turn off ignition switch (25).
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.
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. 28)
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.
Run the engine while adjusting the idling.
(1) If the engine stops during idling
Start the engine, and slowly turn the idle speed
adjustment screw (T) in a clockwise direction until it is in
a position at which the engine rotates smoothly. At that
time, ensure that the cutting attachment is not spinning.
(2) If the cutting attachment rotates during idling
Slowly turn the idle speed adjustment screw (T) in a
counter-clockwise direction until it is in a position at
which the cutting attachment does not rotate. At that
time, ensure that the rotation of the engine is smooth.
WARNING
If the cutting attachment still rotates after adjustment of
the idle speed adjustment screw (T), immediately stop
the engine and cease use, then contact the nearest
HiKOKI Authorized Service Center.
Air fi lter (Fig. 29)
The air fi lter (26) must be cleaned from dust and dirt in order
to avoid:
○ Carburetor malfunctions.
○ Starting problems.
○ Engine power reduction.
○ Unnecessary wear on the engine parts.
○ Abnormal fuel consumption.
Clean the air fi lter daily or more often if working in
exceptionally dusty areas.
Loosen the screw (27), then open the air fi lter cover and
remove the air fi lter (26). Rinse it in warm soap suds.
Check that the fi lter is dry before reassembly.
An air fi lter that has been used for some time cannot be
cleaned completely. Therefore, it must regularly be replaced
with a new one. A damaged fi lter must always be replaced.
