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. (Fig. 7)
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.
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.
