spacer and the pivot sleeve so that they do not fall from
the cutting head.

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)
