Fueling
WARNING
○ Always shut off the engine and let it cool for a few
minutes before refueling.
Do not smoke or bring fl ames or sparks near the fueling
site.
○ Slowly open the fuel tank, when fi lling up with fuel, so
that possible over-pressure disappears.
○ Tighten the fuel tank cap carefully, after fueling.
○ Always move the unit at least 3 m from the fueling area
before starting.
○ Always wash any spilled fuel from clothing immediately
with soap.
○ Be sure to check any fuel leakage after refueling.
○ Before fueling, in order to remove static electricity from
the main body, the fuel container and the operator,
please touch the ground that is slightly damp.
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
CAUTION
Before starting, make sure the cutting attachment does
not touch anything.
(1) Starting the cold engine
1. Set ignition switch (36) to ON position. (Fig. 24)
2. Push priming bulb (37) several times so that fuel fl ows
through return pipe (38). (Fig. 25)
3. Set choke lever (39) to START position (closed) (A).
(Fig. 26)
4. Pull recoil starter briskly, taking care to keep the handle
in your grasp and not allowing it to snap back. (Fig. 27)
5. When you hear the engine want to start, return choke
lever to RUN position (open) (B). (Fig. 26)
6. Pull recoil starter briskly again. (Fig. 27)
NOTE
If engine does not start, repeat procedures from 2 to 5.
7. Then allow the engine about 2–3 minutes to warm up
before subjecting it to any load.
8. Check that the cutting attachment does not rotate when
the engine is idling.
(2) Starting the warm engine
Use only 1, 6 and 8 of the starting procedure for a cold
engine.
If the engine does not start, use the same starting
procedure as for a cold engine.
Cutting
WARNING
○ Always use the harness (if so equipped) and wear the
proper attire and protective equipment when operating
the unit. (Fig. 28)
○ Keep others including children, animals, bystanders and
helpers outside the 15 m hazard zone. Stop the engine
immediately if you are approached. (Fig. 29)
○ When grass or vines wrap around attachment, stop
engine and attachment and remove them. Continuing
operation with grass or vines wrapped around the
attachment may result in damages such as early
abrasion of the clutch.
CAUTION
Use and points of caution will vary depending on the type
of cutting attachment. For safe use, make sure to follow
the instructions and guidelines provided with each type.
NOTE
○ Press the quick release button or pull emergency release
fl ap (If so equipped) in the event of emergency. (Fig. 30)
○ Use in accordance with local laws and regulations.
(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. 31)
○ Cut grass from right to left as the cutting attachment of
the curved drive shaft tube model rotates clockwise.
○ 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.
NOTE
Automatically feeds more nylon cutting line when it is
tapped at low rpm (not greater than 4500 min
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. 32)
○ 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.
Stopping (Fig. 33)
Decrease engine speed and run at an idle for a few minutes,
then turn off ignition switch (36).
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.
