CARBIDE BLADE ASSEMBLY AND
DISASSEMBLY AND ADJUSTMENT OF CUTTER
BLADE HEIGHT (FOR DOUBLE EDGED BLADE
TYPE)
1. Carbide blade disassembly
CAUTION
○ To prevent accidents, ensure that the power tool is
switched off and pull out the battery.
○ Be careful not to injure your hands.
(1) As shown in Fig. 15, loosen the blade holder with the
attached box wrench.
(2) As shown in Fig. 16, remove the carbide blade by sliding
it with the attached box wrench.
2. Carbide blade assembly
CAUTION
○ To prevent accidents, ensure that the power tool is
switched off and pull out the battery.
○ Prior to assembly, thoroughly wipe off all swarf
accumulated on the carbide blade.
(1) As shown in Fig. 17, lift set plate (B) and insert the new
carbide blade between cutter block and set plate (B).
(2) As shown in Fig. 18, 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. 19, 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
○ To prevent accidents, ensure that the power tool is
switched off and pull out the battery.
○ 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. 20, 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. 21, 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. 22, 23, 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. 24, 25, 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. 26, 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.
BLADE ASSEMBLY AND DISASSEMBLY
AND ADJUSTMENT OF BLADE HEIGHT (FOR
RESHARPENABLE BLADE TYPE)
1. Blade disassembly
CAUTION
○ To prevent accidents, ensure that the power tool is
switched off and pull out the battery.
○ Be careful not to injure your hands.
(1) As shown in Fig. 20, use the accessory box wrench
to loosen the three bolts used to retain the blade, and
remove the blade holder.
(2) As shown in Fig. 21, slide the blade in the direction
indicated by the arrow to disassemble the blade.
2. Blade assembly
CAUTION
○ To prevent accidents, ensure that the power tool is
switched off and pull out the battery.
○ Prior to assembly, thoroughly wipe off all swarf
accumulated on the 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. 24, 27)
Set the blade so that both sides of the blade protrude
from the width of the cutter block by about 1 mm (Fig. 28)
(2) Place the blade holder on the completed assembly,
as shown in Fig. 29, 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). (Fig. 30)
(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.
22, 31)
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. 32, 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. 33.
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. Grinding allowance of the cutter blades
As illustrated in Fig. 34, a grinding allowance of 3.5mm
is provided for on the cutter blade. That is, the cutter
blade can be repeatedly sharpened until its total height
is reduced to 24.5 mm.
