CARBIDE BLADE ASSEMBLY AND
DISASSEMBLY AND ADJUSTMENT OF CUTTER
BLADE HEIGHT (FOR DOUBLE EDGED BLADE
TYPE)
1. Carbide blade disassembly
(1) As shown in Fig. 10, loosen the blade holder with the
attached box wrench.
(2) As shown in Fig. 11, remove the carbide blade by
sliding it with the attached box wrench.
CAUTION
Be careful not to injure your hands.
2. Carbide blade assembly
CAUTION
Prior to assembly, thoroughly wipe off all swarf
accumulated on the carbide blade.
(1) As shown in Fig. 12, lift set plate (B) and insert the new
carbide blade between cutter block and set plate (B).
(2) As shown in Fig. 13, mount the new carbide blade
by sliding it on the set plate (B) so that the blade tip
projects by 1mm from the end of the cutter block.
(3) As shown in Fig. 14, fi x the bolts at the blade holder
after blade replacement has been completed.
(4) Turn the cutter block over, and set the other side in the
same manner.
3. Adjustment of carbide blade height
CAUTION
If the carbide blade's heights are inaccurate after
above procedures have been completed, carry out the
procedures described below.
(1) As shown in Fig. 15, use the box wrench to loosen the
three bolts used to retain the carbide blade, and remove
the blade holder.
(2) As shown in Fig. 16, after removing the carbide blade,
slide set plate (B) in the direction indicated by the arrow
to disassemble set plate (B).
(3) Loosen the 2 screws holding on the carbide blade and
set plate (A), set plate (B).
(4) As shown in Fig. 17, 18, press the turned surface of
set plate (A) to the wall surface b while adjusting the
carbide blade edge to the wall surface a of the set
gauge. Then, tighten them with the 2 screws.
(5) As shown in Fig. 19, 20, insert a turned portion of set
plate (A) attached to set plate (B) into a groove on the
fl at portion of the cutter block.
(6) As shown in Fig. 21, place the blade holder on the
completed assembly and fasten it with the three bolts.
Ensure that the bolts are securely tightened. Follow the
same procedures for the opposite side carbide blade.

(1) Insert a turned portion of set plate (A) attached to the
blade into a groove on the fl at portion of the cutter
block. (Fig. 19, 22)
Set the blade so that both sides of the blade protrude
from the width of the cutter block by about 1 mm
(Fig. 23)
(2) Place the blade holder on the completed assembly,
as shown in Fig. 24, and fasten it with the three bolts.
Ensure that the bolts are securely tightened.
(3) Turn the cutter block over, and set the opposite side in
the same manner.
3. Adjustment of blade height
(1) Loosen the 2 screws holding on the blade and set plate
(A).
(2) Press the turned surface of set plate (A) to the wall
surface b while adjusting the blade edge to the wall
surface a of the set gauge. Then, tighten them with the
2 screws. (Fig. 17, 25)

SHARPENING THE RESHARPENABLE BLADES

Use of the accessory Blade Sharpening Ass'y is
recommended for convenience.
1. Use of Blade Sharpening Ass'y
As shown in Fig. 26, two blades can be mounted on
the blade sharpening ass'y to ensure that the blade
tips are ground at uniform angles. During grinding,
adjust the position of the blades so that their edges
simultaneously contact the dressing stone as shown in
Fig. 27.
2. Blade sharpening intervals
Blade sharpening intervals depend on the type of wood
being cut and the cutting depth. However, sharpening
should generally be eff ected after each 500 meters of
cutting operation.
3. Dressing Stone
When a water dressing stone is available, use it after
dipping it suffi ciently in water since such a dressing stone
may be worn during grinding works, fl atten the upper
surface of the dressing stone as often as necessary.
ATTACHING AND DETACHING THE DUST
ADAPTER (OPTIONAL ACCESSORY)

○ To prevent accidents, ensure that the power tool is
switched off and the plug is disconnected from the
power source.
○ Follow the procedure below to mount the dust adapter
securely. Failure to do so may result in the adapter
coming off , causing injury.
1. Attaching the dust adapter
(1) Remove the screw D4 × 16 in the chip cover and remove
