Wheel rotation direction
CAUTION:
Always check the direction of
rotation before operation.
CAUTION:
Use the reversing switch only after
the tool comes to a complete stop. A sudden switch
in rotation direction during operation brings the tool to
a sharp stop for safety reasons.
Wheel rotation can be changed in either forward or
reverse direction.
To set the forward rotation, slide the reversing switch to
the left until "F" indication appears on the switch.
To select the reverse rotation, slide the reversing switch
to the right until "R" indication appears on the switch.
► Fig.4: 1. Reversing switch
Chips, debris, sparks, and cutting particles tend to fly
off along a tangent direction of the wheel rotation. Use
the wheel guard effectively to avoid continued exposure
towards cut-off particles so it can discharge some of
cutting dust and particles into an alternative direction.
A reaction to a rapid stalling of the rotating wheel could make the
tool uncontrolled in the direction opposite to the wheel rotation.

Wheel guard
CAUTION:
Make sure that the wheel guard is
correctly and firmly positioned behind the cutting
wheel before operation.
Secure the wheel guard in a comfortable position, for max-
imum safety and minimum exposure to possible risk fac-
tors, according to your work conditions and preferences.

Shaft lock
Press the shaft lock to prevent spindle rotation when
installing and removing a cutting wheel.
► Fig.9: 1. Shaft lock
NOTICE:
Never actuate the shaft lock when the
spindle is moving. The tool may be damaged.
Operation lamp
CAUTION:
Do not look in the light or see the
source of light directly.
To turn on the operation lamp, press and hold the lock-
off button and pull the switch trigger.
The lamp goes out approximately 15 seconds after
releasing the switch trigger.
► Fig.10: 1. Operation lamp
NOTICE:
When the tool is operated with exces-
sive load, the operation lamp flashes. In this situ-
ation, release the switch trigger, and then reduce
the load on the tool before operating again.
NOTICE:
When the tool is overheated, the opera-
tion lamp flashes. In this case, release the switch
trigger, and then cool down the tool/battery before
operating again.
NOTE: Use a dry cloth to wipe the dirt off the lens of
the lamp. Be careful not to scratch the lens of lamp, or
it may lower the illumination.
Adjusting depth of cut
CAUTION:
After adjusting the depth of cut,
always tighten the thumb screw securely.
With the dust collection cover installed, fine adjustments
in the cutting depth can be made up to 13.5 mm.
Loosen the thumb screw on the depth scale. Lift or
lower the tool handle into position to align the depth
indicators on the cover with your desired cutting depth
on the scale. Then tightening the thumb screw.

indicator
CAUTION:
For clean and safe cutting, set the
cutting depths so that a cutting wheel overpasses the
undersurface of workpiece by 2.0 mm or less. Setting
in proper cutting depths helps to reduce potential
for dangerous kickbacks which may cause personal
injury.
Sighting for straight cutting
With the dust collection cover installed, straight cut
operation can safely be performed by aligning the cut-
ting wheel toward the cutting direction before the actual
cut operation.
Align the guide notch in the base of dust collection
cover with your intended cutting line on the workpiece.

Connecting a vacuum cleaner
Optional accessory
When you wish to perform clean cutting operation,
connect a Makita vacuum cleaner to the dust nozzle in
the dust collection cover using a front cuffs 22 (optional
accessory).

Accidental re-start preventive
function
When installing the battery cartridge while pulling the
switch trigger, the tool will not start.
To start the tool, release the switch trigger first. Press
and hold the lock-off button, and then pull the switch
trigger.
