To remove the battery cartridge, withdraw it from the tool
while pressing the buttons on both sides of the cartridge.
To install the battery cartridge, hold it so that the battery
cartridge front shape fits to that of the battery installment
opening and slip it into place. Insert it all the way until it
locks in place with a little click.
CAUTION:
• Always insert the battery cartridge all the way until it
locks in place. If not, it may accidentally fall out of the
tool, causing injury to you or someone around you.
• Do not install the battery cartridge forcibly. If the
cartridge does not slide in easily, it is not being inserted
correctly.
Battery protection system
The tool is equipped with a battery protection system. This
system automatically cuts off power to the motor to extend
battery life.
The tool will automatically stop during operation if the tool
and/or battery are placed under one of the following
conditions:
• Overloaded:
The tool is operated in a manner that causes it to
draw an abnormally high current.
In this situation, release the switch trigger on the tool
and stop the application that caused the tool to
become overloaded. Then pull the switch trigger
again to restart.
• Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. If you pull the switch trigger, the
motor runs again but stops soon. In this situation,
remove and recharge the battery.
Adjusting depth of cut (Fig. 8)
CAUTION:
• After adjusting the depth of cut, always tighten the
clamping screw securely.
Loosen the clamping screw on the depth guide and move
the base up or down. At the desired depth of cut, secure
the base by tightening the clamping screw.
For cleaner, safer cuts, set cut depth so that no more than
one blade tooth projects below workpiece. Using proper
cut depth helps to reduce potential for dangerous
KICKBACKS which can cause personal injury.
Bevel cutting (Fig. 9)
Loosen the clamping screw on the bevel scale plate on
the front of the base. Set for the desired angle (0° - 45°)
by tilting accordingly, then tighten the clamping screw
securely.
Sighting (Fig. 10)
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. 11)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released.

• Do not pull the switch trigger hard without pressing the
lock-off lever. This can cause switch breakage.
To prevent the switch trigger from being accidentally
pulled, a lock-off lever is provided. To start the tool, slide
the lock-off lever and pull the switch trigger. Release the
switch trigger to stop.
WARNING:
• For your safety, this tool is equipped with lock-off lever
which prevents the tool from unintended starting.
NEVER use the tool if it runs when you simply pull the
switch trigger without pressing the lock-off lever. Return
tool a MAKITA service center for proper repairs
BEFORE further usage.
• NEVER tape down or defeat purpose and function of
lock-off lever.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.
Removing or installing saw blade (Fig. 12)
CAUTION:
• 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 fully 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. (Fig. 13)
To install the blade, follow the removal procedure in
reverse. BE SURE TO TIGHTEN THE HEX BOLT
CLOCKWISE SECURELY. (Fig. 14)
NOTE:
• If a inner flange is removed by chance, install the inner
flange so that its protrusion (bigger side) faces inside
as shown in the figure.
When changing blade, make sure to also clean upper and
lower blade guards of accumulated sawdust. Such efforts
do not, however, replace the need to check lower guard
operation before each use.
Hex wrench storage (Fig. 15)
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
Connecting a vacuum cleaner
Optional accessory (Fig. 16 & 17)
When you wish to perform clean cutting operation,
connect a Makita vacuum cleaner to your tool. Install the
dust nozzle (accessory) on the tool using the screw. Then
connect a hose of the vacuum cleaner to the dust nozzle
as shown in the figure.
OPERATION
CAUTION:
• Be sure to move the tool forward in a straight line
gently. Forcing or twisting the tool will result in
