ASSEMBLY PROCEDURES
Drive shaft to engine (Fig. 1)
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 fitting 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 straight shaft
trimmers or 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 indication.
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
firmly 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.
Throttle wire / stop cord
Remove air cleaner cover. (Fig. 5)
Loosen and remove the screw from the throttle wire
holder. (Fig. 7)
Connect the terminals of the stop cords coming out from
the engine and shaft. (Fig. 6)
Hook the throttle wire end on the throttle of the carburetor.
Make sure that the throttle trigger shown in Fig. 18 has
returned to the starting position.
Put the throttle outer end into the groove, and then cover
it with the throttle wire holder and fix the holder with the
screw. (Fig. 8)
Then, install the cleaner cover.
Fix the protection tube which the stop cords and throttle
wire are passing through, on the pipe with the hip pad.
Then, as shown in the figure, fix the protection tube on the
pipe and handle with the bands in the bag.
After fixing, cut offthe extra part of the band not to
obstruct the operation. (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.
Some models may come with the parts pre-installed.
Installation of blade guard (Fig. 10)
The guard bracket already mounted to the drive shaft tube.
Attach the gear case cover with the three screws.
Install the blade guard on drive shaft tube against angle
transmission (5). Tighten the guard bracket firmly 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. 12)
Installation of cutting blade (Fig. 13)
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 fixing nut clockwise and
remove the fixing nut, 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. 15), the
cutter holder cap and toothed lock washers onto the cutter
holder in this order. Finally, tighten the fixing nut securely
by turning counterclockwise with the Combi box spanner.
(Fig. 13)
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 fixing nut to prevent the cutting blade from being
eccentric. (Fig. 14)
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.
○Cutter holder cap 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.
NOTE
The blade must be retained with a new cotter pin each
time installed. (Fig. 13)
Installation of nylon head (Fig. 16)
Attach cutter holder (7) to the gear case. Insert an Allen
wrench into the hole in the gear case to attach winding
protector (6) and attach nylon head (8) by turning it
