Installation of cutting blade (Fig. 15)
(If so equipped)
When installing a cutting blade, make sure that there are no cracks
or any damage in it and that the cutting edges are facing the correct
direction.
NOTE
○ When installing cutter holder cap (15), be sure to set concave
side upward.
○ Insert the alien wrench (13) into the hole of the angle
transmission in order to lock the cutter holder (14). Please note
that the cutter fi xing bolt or nut (16) has left-handed threads,
(clockwise to loosen/ counter-clockwise to tighten). Tighten the
fi xing bolt or nut with the box wrench.
○ If your unit is of a nut securing type and equipped with a cotter
pin, the blade must be retained with a new pin (17) each time
installed. (Fig. 16)
CAUTION
○ Before operation, make sure the blade has been properly
installed. (Fig. 17)
○ If your unit is equipped with protection cover under a cutting
blade, check it for wear or cracks before operation. If any
damage or wear is found, replace it, as it is an article of
consumption.
WARNING
For Hitachi heads, use only fl exible, non-metallic line
recommended by the manufacturer. Never use wire or wire
ropes. They can break off and become a dangerous projectile.

OPERATING PROCEDURES

Fuel (Fig. 18)
WARNING
○ The trimmer is equipped with a two-stroke engine. Always run
the engine on fuel, which is mixed with oil.
Provide good ventilation, when fueling or handling fuel.
○ Fuel contains highly fl ammable and it is possible to get the
serious personal injury when inhaling or spilling on your body.
Always pay attention when handling fuel. Always have good
ventilation when handling fuel inside building.
Fuel
○ Always use branded 89 octane unleaded gasoline.
○ Use genuine two-cycle oil or use a mix between 25:1 to 50:1,
please consult the oil bottle for the ratio or Hitachi Authorized
Service Centers.
○ If genuine oil is not available, use an anti-oxidant added quality
oil expressly labeled for air-cooled 2-cycle engine use (JASO
FC GRADE OIL or ISO EGC GRADE). Do not use BIA or TCW
(2-stroke water-cooling type) mixed oil.
○ Never use multi-grade oil (10 W/30) or waste oil.
○ Always mix fuel and oil in a separate clean container.
Always start by fi ling half the amount of fuel, which is to be used.
Then add the whole amount of oil. Mix (shake) the fuel mixture. Add
the remaining amount of fuel.
Mix (shake) the fuel-mix thoroughly before fi lling the fuel tank.
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
CAUTION
Before starting, make sure the cutting attachment does not
touch anything.
1. Slide ignition switch (18) to START position. (Fig. 19)
* Push priming bulb (21) several times so that fuel fl ows through
return pipe. (Fig. 20)
2. With the safety trigger (19) (if so equipped) pressed, pull
throttle trigger and push throttle lock (20). Then slowly release
the throttle trigger fi rst, then the safety trigger. This will lock the
throttle in starting position.
3. Set choke lever (22) to START position (closed) (A). (Fig. 21)
4. Pull recoil starter briskly, taking care to keep the handle in your
grasp and not allowing it to snap back. (Fig. 22)
5. When you hear the engine want to start, return choke lever to
RUN position (open) (B). Then pull recoil starter briskly again.
NOTE
If engine does not start, repeat procedures from 3 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.
7. Check that the cutting attachment does not rotate when the
engine is idling.
Cutting (Fig. 23, 24, 25)
○ When cutting, operate engine at over 6500 min
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.
○ Use in accordance with local laws and regulations.
NOTE
Pull emergency release fl ap in the event of emergency.
(Fig. 26)
How to use the shoulder harness
Wear the shoulder harness on your shoulder as shown Fig. 24
and hook it on the hanger of the machine. Adjust the length of the
shoulder harness to the most comfortable position. (Fig. 24)
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
(24) of the shoulder harness from the hanger (25). (Fig. 26-a)
How to reinstall the hook after using the emergency release
pinch
It needs to go through the buckle (26) of the hook (24) to the metal
plate (27) on the harness and go through the plate (28) of the
emergency release pinch to the metal plate (27) on the harness.
(Fig. 26-b)
After installing the buckle onto the harness, pull the hook (24) and
make sure the hook (24) is securely fi xed on the harness, then hook
it to the hanger (25). (Fig. 26-a)
