Positive stopper
The positive stopper is useful for setting the des-
ignated angle quickly. Turn the positive stopper so
that the arrow on it points your desired bevel angle
(22.5°/45°/60°). Loosen the lever and the clamping
screw and then tilt the tool base until it stops. The posi-
tion where the tool base stops is the angle you set with
the positive stopper. Tighten the lever and clamping
screw with the tool base at this position.
► Fig.14: 1. Positive stopper
-1°-bevel cutting
To perform -1°-bevel cutting, loosen the lever and the
clamping screw. Set the bevel angle to -1° while turning
the stopper lever in the direction of the arrow. After that,
tighten the lever and the clamping screw.

Sighting
For straight cuts, align the 0° position on the front of the
base with your cutting line. For 45° bevel cuts, align the
45° position with it.

Lighting the lamp
CAUTION:
Do not look in the light or see the
source of light directly.
To turn on the lamp without running the tool, pull the
switch trigger without pressing the lock-off button.
To turn on the lamp with the tool running, press and hold
the lock-off button and pull the switch trigger.
The lamp goes out 10 seconds after releasing the
switch trigger.

NOTE: Use a dry cloth to wipe the dirt off the lens of
the lamp. Be careful not to scratch the lens of lamp, or
it may lower the illumination.
Electric brake
This tool is equipped with an electric blade brake. If the
tool consistently fails to quickly stop the circular saw
blade after switch lever release, have tool serviced at a
Makita service center.
CAUTION:
The blade brake system is not a
substitute for blade guard. NEVER USE TOOL
WITHOUT A FUNCTIONING BLADE GUARD.
SERIOUS PERSONAL INJURY CAN RESULT.
Electronic function
The tools equipped with electronic function are easy to
operate because of the following feature(s).
Soft start feature
Soft start because of suppressed starting shock.
ASSEMBLY

Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
Hex wrench storage

Removing or installing circular saw
blade
CAUTION:
Be sure the circular saw blade is
installed with teeth pointing up at the front of the
tool.
CAUTION:
Use only the Makita wrench to
install or remove the circular saw blade.
To remove the circular saw blade, press the shaft lock
fully so that the circular saw blade cannot revolve and
use the hex wrench to loosen the hex bolt. Then remove
the hex bolt, outer flange, circular saw blade and ring
(country specific).

To install the circular saw blade, follow the removal
procedure in reverse.
For tool with the inner flange for
other than 15.88 mm hole-diameter
saw blade
The inner flange has a certain diameter protrusion on
one side of it and a different diameter protrusion on the
other side. Choose a correct side on which protrusion
fits into the saw blade hole perfectly. Mount the inner
flange onto the mounting shaft so that the correct side
of protrusion on the inner flange faces outward and then
place saw blade and outer flange.

WARNING:
BOLT CLOCKWISE SECURELY. Also be careful
not to tighten the bolt forcibly. Slipping your hand
from the hex wrench can cause a personal injury.
