Tips for maintaining maximum battery life

1. Charge the battery cartridge before completely 

discharged. Always stop tool operation and 

charge the battery cartridge when you notice less 

tool power.

2. Never recharge a fully charged battery cartridge. 

Overcharging shortens the battery service life.

3. Charge the battery cartridge with room 

temperature at 10°C - 40°C (50°F - 104°F). Let a hot 

battery cartridge cool down before charging it.

FUNCTIONAL DESCRIPTION

CAUTION:

• Always be sure that the tool is switched off and the 

battery cartridge is removed before adjusting or 

checking function on the tool.

Installing or removing battery cartridge 

(Fig. 1)

• Always switch off the tool before insertion or removal of 

the battery cartridge.

• To remove the battery cartridge, withdraw it from the 

tool while sliding the button on the side of the cartridge.

• To insert the battery cartridge, align the tongue on the 

battery cartridge with the groove in the housing and slip 

it into place. Always insert it all the way until it locks in 

place with a little click. If you can see the red part on 

the upper side of the button, it is not locked completely. 

Insert it fully until the red part cannot be seen. If not, it 

may accidentally fall out of the tool, causing injury to 

you or someone around you.

• Do not use force when inserting the battery cartridge. If 

the cartridge does not slide in easily, it is not being 

inserted correctly.

Adjusting depth of cut (Fig. 2)

CAUTION:

• After adjusting the depth of cut, always tighten the lever 

securely.

Loosen the lever on the side of the rear handle and move 

the base up or down. At the desired depth of cut, secure 

the base by tightening the lever.

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.

Sighting (Fig. 3)

When cutting, align the A position on the front of the base 

with your cutting line on the workpiece.

Switch action (Fig. 4)

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, press 

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.

Lighting the lamp (Fig. 5)

CAUTION:

• Do not look in the light or see the source of light 

directly.

Only to turn on the light, pull the switch trigger without 

pressing the lock-off lever. To turn on the light and run the 

tool, press the lock-off lever and pull the switch trigger 

with the lock-off lever being pressed.

NOTE:

• Use a cotton stick to wipe the dirt off the lens of lamp. 

Be careful not to scratch the lens of lamp, or it may 

lower the illumination.

• Do not use gasoline, thinner or the like to clean the lens 

of lamp. Using such substances will damage the lens.

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 blade (Fig. 6)

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 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. (Fig. 7)

When changing blade, make sure to also clean upper and 

lower blade guards of accumulated chips and particles. 

Such efforts do not, however, replace the need to check 

lower guard operation before each use. 

Hex wrench storage (Fig. 8)

When not in use, store the hex wrench as shown in the 

figure to keep it from being lost.

OPERATION

CAUTION:

• Always insert the battery cartridge all the way until it 

locks in place. If you can see the red part on the upper
