rotating slightly.
Release lock-pin to lock in the location hole (22).
Installation of handle
WARNING
When you use steel/rigid blades on brush cutters, always use
a barrier bar (5) and shoulder harness with the loop handle.
(Fig. 3)
Attach the handle to the drive shaft tube with the angle towards the
engine.
Adjust the location to the most comfortable position before
operation.
Throttle wire / stop cord
Remove air cleaner cover. (Fig. 4)
Connect stop cords. (Fig. 5)
Insert the stay (6) under the nut (7) screwed onto the outer end of
the throttle wire (8) and connect the end of the throttle wire (9) to the
carburetor (10). Then tighten the nut (7) to secure the throttle wire to
the stay (6). (Fig. 6)
NOTE
Check that the carburetor throttle returns to the idle position
and also that it can be opened wide by operating the throttle
lever.
Cover throttle wire and stop cords together with protective tube
provided up to air cleaner cover. (Fig. 7)
Some models may come with the throttle wire and stop cords
already installed.
Installation of gear case cover (Fig. 8)
Attach the gear case cover (11) with the three screws, making sure
to align the notch (12) in the gear case with the hole (13) in the gear
case cover.
Installation of blade guard (Fig. 9)
The guard bracket already mounted to the drive shaft tube.
Install the blade guard on drive shaft tube against angle
transmission (14). Tighten the guard bracket fi rmly so that the blade
guard does not swing or move down during operation.
CAUTION
The blade guard must be in place during operation.
If the blade guard is not in place, there is a possibility of serious
injury.
Guard extension are equipped with sharp line limiter. Be careful
with handling it.
Installation of cutting blade (Fig. 12)
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.
Align the notch hole of the cutter holder with the hole on the gear
case cover and insert the Allen wrench to stop turning. Turn the
fi xing nut clockwise and remove the fi xing nut, protection cover,
cutter holder cap, and toothed lock washers.
The installation of the cutting blade is as follows: insert the Allen
wrench into the notch hole of the cutter holder and the hole on
the gear case. Then, install the cutting blade (check the installing
10
direction, as referring to Fig. 14), the cutter holder cap, protection
cover and toothed lock washers onto the cutter holder in this order.
Finally, tighten the fi xing nut securely by turning counterclockwise
with the Combi box spanner. (Fig. 12)
CAUTION
○ When installing the cutting blade, set its center hole to the
convex part of the cutter holder and hold it with the concave
surface of the cutter holder cap. Then, tighten the fi xing nut to
prevent the cutting blade from being eccentric. (Fig. 12)
After installing the cutting blade, be sure to remove the Allen
wrench and Combi box spanner.
○ Before operation, make sure the blade has been properly
installed. (Fig. 13)
○ Before operation, check the cutter holder cap under the cutting
blade for wear or cracks. If any damage or wear is found,
replace it, as it is an article of consumption.
NOTE
The blade must be retained with a new cotter pin each time
installed. (Fig. 12)
Installation of nylon head (Fig. 15)
If your unit has nylon head, follow the installation.
Attach cutter holder (15) to the gear case. Insert an Allen wrench
into the hole in the gear case to attach winding protector (16) and
attach nylon head (17) by turning it clockwise.
NOTE
○ Since cutter holder cap is not used here, keep it for next metal
blade use.
○ To attach the guard extension, refer to the drawings. Wear
gloves as the extension has a sharp line limiter, then push the
guard extension to blade guard when make sure put on two
tabs.
After attach the screw. (Fig. 10, 11)

OPERATING PROCEDURES

Fuel (Fig. 16)
WARNING
○ The backpack brush cutter 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 is highly fl ammable and toxic and can result in serious
injury if it is inhaled or comes into contact with your skin. Always
handle fuel with care. 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 dealer.
○ 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.
