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.

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 (1/16"-1/8") 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.
