Remove the two screws (middle and front) which hold the
cutting head. When removing the middle screw, be care-
ful 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 cut-
ting 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 repo-
sitioning 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 reposi-
tioned 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.
