Tool speed is increased by increasing pressure on the

switch trigger. Release the switch trigger to stop. After

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 adhering 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. (Fig. 5)

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. (Fig. 6)

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. (Fig. 7)

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.

OPERATION (Fig. 8)

CAUTION:

• Always press the shoe firmly against the workpiece

during operation. If the shoe is held away from the

workpiece during operation, strong vibration and/or

twisting will be produced, causing the blade to snap

dangerously.

• Always wear gloves to protect your hands from hot

flying chips when cutting metal.

• Be sure to always wear suitable eye protection which

conforms with current national standards.

• Always use a suitable coolant (cutting oil) when cutting

metal. Failure to do so will cause premature blade

wear.

• If the tool is operated continuously until the battery

cartridge has discharged, allow the tool to rest for 15

minutes before proceeding with a fresh battery.

Press the shoe firmly against the workpiece. Do not allow

the tool to bounce. Bring the blade into light contact with

the workpiece. First, make a pilot groove using a slower

speed. Then use a faster speed to continue cutting.

NOTE:

• If the tool is operated continuously until the battery

cartridge has discharged, allow the tool to rest for

15 minutes before proceeding with a fresh battery.

MAINTENANCE

CAUTION:

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

battery cartridge is removed before attempting to

perform inspection or maintenance.

• Never use gasoline, benzine, thinner, alcohol or the

like. Discoloration, deformation or cracks may result.

Replacing carbon brushes (Fig. 9 & 10)

Remove and check the carbon brushes regularly.

Replace when they wear down to the limit mark. Keep the

carbon brushes clean and free to slip in the holders.

Both carbon brushes should be replaced at the same

time. Use only identical carbon brushes.

Use a screwdriver to remove the brush holder caps.

Take out the worn carbon brushes, insert the new ones

and secure the brush holder caps.

To maintain product SAFETY and RELIABILITY, repairs,

any other maintenance or adjustment should be

performed by Makita Authorized Service Centers, always

using Makita replacement parts.
