Loosen tube locking bolt (1) about ten turns so that the bolt point will
not obstruct drive shaft tube to be inserted. When inserting drive
shaft tube, hold the tube locking bolt outward preventing inside
fi tting from obstructing as well.
Some models may come with the drive shaft already installed.
NOTE
When it is hard to insert drive shaft up to the marked position on
the drive shaft tube, turn drive shaft by the cutter mounting end
clockwise or counter-clockwise. Tighten tube locking bolt lining
up the hole in the shaft tube. Then tighten clamp bolt securely
(1).
Installation of handle
WARNING
When you use steel/rigid blades on brush cutters, always use
a barrier bar (2) and shoulder harness with the loop handle.
(Fig. 2)
Attach the handle to the drive shaft tube with the angle towards the
engine.
Adjust the location to the most comfortable position before
operation.
NOTE
If your unit has handle location label on drive shaft tube, follow
the illustration.
Remove the handle bracket (3) from the assembly. (Fig. 3)
Place the handles and attach the handle bracket with four bolts
lightly. Adjust to appropriate position. Then attach it fi rmly with the
bolts.
Attach the protection tube to the drive shaft or handle using cord
clamps (4). (Fig. 4)
NOTE
If the protection tube is set apart from the handle or pipe, it will
be caught by something during operation and it may cause
serious injury. Do not set the protection tube apart from the
handle or pipe.

Remove air cleaner cover. (Fig. 5)
Connect stop cords. (Fig. 6)
Insert the stay (5) under the nut (6) screwed onto the outer end of
the throttle wire (7) and connect the end of the throttle wire (8) to the
carburetor (9). Then tighten the nut (6) to secure the throttle wire to
the stay (5). (Fig. 7)
NOTE

provided up to air cleaner cover. (Fig. 8)
Some models may come with the throttle wire and stop cords
already installed.
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 (10). 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.
Blade guards are equipped with sharp line limiter. Be careful with
handling it.
NOTE
○ When attaching the guard extension to the blade guard, the
sharp line limiter must be removed from the blade guard.
○ To remove the guard extension, refer to the drawings. Wear
gloves as the extension has a sharp line limiter, then push the
two square tabs on the guard one by one in order after removed
the screw. (Fig. 11)
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 (Top the gear case) 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
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.
○ 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
Attach cutter holder (11) to the gear case. Insert an Allen wrench
into the hole in the gear case to attach winding protector (12) and
attach nylon head (13) by turning it clockwise.
NOTE
Since cutter holder cap is not used here, keep it for next metal
blade use.
