NOTE:

• When the handle cannot be moved easily, loosen the

bolts furthermore.

Shifting the front handle sideways (Fig. 12)

Remove the two bolts on both sides of the front handle

with the hex wrench. Change the position of the cam.

Insert the longer bolt to the side close to the cam and the

shorter one to the opposite side. Tighten the two bolts

firmly.

Connecting to vacuum cleaner (Fig. 13)

When using Makita dust collector, connect the hose for

the vacuum cleaner directly to the dust nozzle.

NOTE:

• The dust nozzle can be rotated freely so that you can

use it at any angle according to your operation.

Hex wrench storage (Fig. 14)

When not in use, store the hex wrench to keep it from

being lost.

OPERATION

CAUTION:

• Be sure to pull the tool when cutting a workpiece.

• Use this tool for straight line cutting only. Cutting curves

can cause stress cracks or fragmentation of the

diamond wheels resulting in possible injury to persons

in the vicinity.

• After operation, always switch off the tool and wait until

the diamond wheels come to a complete stop before

putting the tool down.

• Hold the tool firmly with one hand on the switch handle

and the other hand on the front grip when performing

the tool.

Hold the tool firmly with both hands. First keep the

diamond wheels without making any contact with a

workpiece. Then turn the tool on and wait until the

diamond wheels attain full speed. (Fig. 15)

To cut a workpiece, pull the tool toward you (not by

pushing away from you). Align the notch on the base with

your cutting line. Push down the front handle gently until

it stops and then pull the tool slowly. (Fig. 16)

Before finishing cutting operation and raising the tool,

switch it off first. Wait until the diamond wheels stop

completely and then raise the tool.

Remove the remaining portion between the two blade

passages by other appropriate tools.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and

unplugged before attempting to perform inspection or

maintenance.

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

like. Discoloration, deformation or cracks may result.

The tool and its air vents have to be kept clean. Regularly

clean the tool’s air vents or whenever the vents start to

become obstructed. (Fig. 17)

Dressing diamond wheel

If the cutting action of the diamond wheel begins to

diminish, use an old discarded coarse grit bench grinder

wheel or concrete block to dress the diamond wheel. To

do this, tightly secure the bench grinder wheel or

concrete block and cut in it.

To maintain product SAFETY and RELIABILITY, repairs,

carbon brush inspection and replacement, any other

maintenance or adjustment should be performed by

Makita Authorized Service Centers, always using Makita

replacement parts.
