FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Adjusting depth of cut (Fig. 1)
CAUTION:
• Use a shallow depth of cut when cutting thin workpiece
for cleaner, safer cutting.
• After adjusting the depth of cut, always tighten the lever
securely.
Loosen the lever on the depth guide and move the base
up or down. At the desired depth of cut, secure the base
by tightening the lever.
Bevel cutting (Fig. 2)
Loosen the clamping screws in front and back, and tilt the tool to the desired angle for bevel cuts (0° – 50°). Secure
the clamping screws tightly in front and back after making
the adjustment.
Sighting (Fig. 3)
For straight cuts, align the A position on the front of the
base with your cutting line. For 45° bevel cuts, align the B
position with it.
Switch action (Fig. 4)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.

• Be sure the blade is installed with teeth pointing up at
the front of the tool.
• Use only the Makita wrench to install or remove the
blade.
To remove the blade, press the shaft lock so that the
blade cannot revolve and use the wrench to loosen the
hex bolt counterclockwise. Then remove the hex bolt,
outer flange and blade.
To install the blade, follow the removal procedure in
reverse. BE SURE TO TIGHTEN THE HEX BOLT
CLOCKWISE SECURELY.

Blade guard cleaning
When changing the circular saw blade, make sure to also
clean the upper and lower blade guards of accumulated
sawdust as discussed in the Maintenance section. Such
efforts do not replace the need to check lower guard
operation before each use.
Side grip (auxiliary handle) (Fig. 7)
Install the side grip on the tool securely before operation.
Joint set (Accessory) (Fig. 8 & 9)
Attach the joint to the chip chute in the blade case and
secure it with the screws.
Remove the lever attached to the main unit and attach
lever of joint set.
OPERATION
CAUTION:
• Be sure to move the tool forward in a straight line
gently. Forcing or twisting the tool will result in
overheating the motor and dangerous kickback,
possibly causing severe injury.
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. Set the base on the workpiece to be cut without
the blade making any contact. Then turn the tool on and
wait until the blade attains full speed. Now simply move
the tool forward over the workpiece surface, keeping it
flat and advancing smoothly until the sawing is
completed. To get clean cuts, keep your sawing line
straight and your speed of advance uniform. If the cut
fails to properly follow your intended cut line, do not
attempt to turn or force the tool back to the cut line. Doing
so may bind the blade and lead to dangerous kickback
and possible serious injury. Release switch, wait for
blade to stop and then withdraw tool. Realign tool on a
new cut line, and start cut again. Attempt to avoid
positioning which exposes operator to chips and wood
dust being ejected from saw. Use eye protection to help
(Fig. 10)
avoid injury.
Rip fence (Guide rule) (Fig. 11)
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 screw on the front of the base. It also makes
repeated cuts of uniform width possible.
