Hook
The hook is convenient for temporary hanging the tool.
When using the hook, pull it out in “A” direction and then 
push it in “B” direction to secure in place. (Fig. 2 & 3)
When not using the hook, return it back to its initial 
position by following the above procedures in reverse.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and 
unplugged before carrying out any work on the tool.
Replacement of blades
CAUTION:
• Never remove the blades with bare hands. Wear 
gloves. Otherwise it can cause injury.
Removing cutting head (Fig. 4)
Use the hex wrench to loosen the three screws which 
secure the cutting head. Pull the cutting head straight out 
to remove it with turning it left and right alternately.
Removing shear blades (Fig. 5)
Remove the two screws (middle and front) which hold the 
cutting head. When removing the middle screw, be careful 
not to lose the spacer. Then the blades can be removed 
easily. When removing the blades, hold the blades, the 
spacer and the pivot sleeve so that they do not fall from 
the cutting head.
Installing shear blades (Fig. 6)
Install the spacer and the pivot sleeve and tighten the 
three screws after inserting the center blade, side blades 
into the cutting head. In this process, the screw heads 
should be protruding 2 - 3 mm from the cutting head 
surface.
If you will tighten the screws excessively, the cutting head 
cannot be installed to the tool.
NOTE:
• Side blade edge can be used in four ways by 
repositioning them left-to-right and end-to-end as 
shown in the figure.
The following describes time and procedure to change 
blades.
A) When the two side blades have rounded about half 
their width, they can be repositioned left-to-right for 
new cutting edges.
B) When both edges of each side blade have rounded 
about half their width, reposition them end-to-end for 
two new cutting edges.
C) When all edges have worn down, obtain replacements 
from Makita authorized or factory service center.
D) When side blades are worn out, the center blade 
should also be replaced. (Fig. 7)
Installing cutting head (Fig. 8)
CAUTION:
• Secure the cutting head firmly. Otherwise it can rotate 
during operation and can cause serious injury.
Insert the cutting head into the tool with turning it left and 
right alternately. Then tighten the three screws with the 
hex wrench.

CAUTION:
• This tool is intended for cutting fiber cement material 
only, with a thickness of 8 mm or less. Do not cut other 
materials or stack-cut. Doing so will damage the tool
