To prevent the switch trigger from being accidentally

pulled, a lock-off button is provided.

To start the tool, press in the lock-off button and pull the

switch trigger. The lock-off button can be pressed in from

either left or right side of the tool. Tool speed is increased

by increasing pressure on the switch trigger. Release the

switch trigger to stop.

Electric brake

This tool is equipped with an electric brake. If the tool

consistently fails to quickly stop after switch trigger

release, have tool serviced at a Makita service center.

Speed change

CAUTION:

• Always set the speed change lever fully to the cor-

rect position. If you operate the tool with the speed

change lever positioned half-way, the tool may be

damaged.

• Do not use the speed change lever while the tool is

running. The tool may be damaged.

To change the speed, first switch off the tool and then

slide the speed change lever to the A side (2) for high

speed or B side (1) for low speed. Be sure that the speed

change lever is set to the correct position before opera-

tion. Use the right speed for your job.

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.

Installing or removing the saw blade

CAUTION:

• Always clean out all chips or foreign matter adher-

ing to the blade, blade clamp and/or slider. Failure

to do so may cause insufficient tightening of the

blade, resulting in a serious injury.

To install the saw blade, always make sure that the blade

clamp sleeve is in released position before inserting the

saw blade. If the blade clamp sleeve is in fixed position,

rotate the sleeve to the released position.

Insert the saw blade into the blade clamp as far as it will

go. The blade clamp sleeve rotates and the saw blade is

fixed. Make sure that the saw blade cannot be extracted

even though you try to pull it out.

NOTE:

• If you do not insert the saw blade deep enough, the

saw blade may be ejected unexpectedly during

operation. This can be extremely dangerous.

To remove the saw blade, rotate the blade clamp sleeve

in the direction of the arrow fully. The saw blade is

removed and the blade clamp sleeve is fixed at the

released position.

NOTE:

• If you remove the saw blade without rotating the

blade clamp sleeve fully, the sleeve may not be

fixed. In this case, rotate the blade clamp sleeve

fully, then make the sleeve fixed at the released

position.
