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

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 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 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.

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 ﬁ x 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

ﬁ gure, ﬁ x the protection tube on the pipe and handle with the bands

in the bag.

After ﬁ xing, cut oﬀ the 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 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. 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 ﬁ xing nut clockwise and remove the ﬁ xing 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

ﬁ xing 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 ﬁ xing 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 (6) to the gear case. Insert an Allen wrench

into the hole in the gear case to attach nylon head (7) by turning it

clockwise.

NOTE

Since cutter holder cap is not used here, keep it for next metal

blade use.
