To install the blade, follow the removal procedure in
reverse. Be sure to tighten the hex bolt clockwise
securely. And close the blade case door after installing

When changing blade, make sure to also clean the
guard of accumulated sawdust and chips as discussed
in the Maintenance section. Such efforts do not replace
the need to check guard operation before each use.

Rip fence (guide rule)
Optional accessory
CAUTION:
Do not use the rip fence with the
groove cutter blade. Use the rip fence only when
using the tool with the circular saw blade (optional
accessory).
► Fig.19: 1. Rip fence (guide rule)
The handy rip fence allows you to do extra-accurate
straight cuts. Simply slide the rip fence up snugly
against the side of the workpiece and secure it in
position with the screws on the front and the back of
the base. It also makes repeated cuts of uniform width
possible.
Overturning the rip fence (guide rule) also works as a
sub base for the tool.
Stopper for 2 to 3 mm depth of
cut when using circular saw blade
(optional accessory) and guide rail
(optional accessory)
► Fig.20: 1. Stopper 2. Red mark
This tool has the stopper for 2 to 3 mm depth of cut
on the gear housing aside the rear handle when using
guide rail.
Splinter on the workpiece can be avoided by making a
pass of the 2 to 3 mm first cut and then make another
pass of usual cut.
First, push in the stopper toward the circular saw blade
for obtaining 2 to 3 mm depth of cut.
Then pull the button back for performing free depth of
cut.
Make sure that the stopper is released and the red mark
can be seen for groove cutting operation.
Connecting a vacuum cleaner
For groove cutting operation, connect a Makita vacuum
cleaner to your tool.
Connect a hose of the vacuum cleaner to the dust port.

Groove cutting

CAUTION:
Be sure to move the tool forward
in a straight line gently. Forcing or twisting the tool
may result in overheating the motor and dangerous
kickback, possibly causing severe injury.
CAUTION:
Never approach any part of your
body under the tool base when section cutting,
especially at starting. Doing so may cause serious
personal injuries. The blade is exposed under the tool
base.
CAUTION:
Use eye protection to avoid injury.
CAUTION:
For groove cutting operation,
always connect the tool to a vacuum cleaner.

Hold the tool firmly. The tool is
provided with both a front grip and rear handle.
Use both to best grasp the tool. If both hands are
holding saw, they cannot be cut by the blade.
