Lamp
CAUTION:
Do not look in the light or see the
source of light directly.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The lamp goes out approximately 10 seconds after
releasing the switch trigger.
NOTICE:
If the lamp goes off after blinking for a
few seconds, the active feedback sensing tech-
nology is not working properly. Ask your local
Makita Service Center for repair.
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.
Selecting the action mode
NOTICE:
Do not rotate the action mode changing
knob when the tool is running.
The tool will be damaged.
NOTICE:
To avoid rapid wear on the mode
change mechanism, be sure that the action mode
changing knob is always positively located in one
of the three action mode positions.
Rotation with hammering
For drilling in concrete, masonry, etc., rotate the action
mode changing knob to the
symbol. Use a car
-
bide-tipped drill bit.

Torque limiter
NOTICE:
As soon as the torque limiter actuates,
switch off the tool immediately.
This will help pre-
vent premature wear of the tool.
NOTICE:
Drill bits such as hole saw, which tend
to pinch or catch easily in the hole, are not appro-
priate for this tool.
This is because they will cause
the torque limiter to actuate too frequently.
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the
output shaft. When this happens, the drill bit will stop
turning.
Electronic function
The tool is equipped with the electronic functions for
easy operation.
Constant speed control
The speed control function provides the constant rota-
tion speed regardless of load conditions.
Soft start
The soft-start function minimizes start-up shock, and
makes the machine start smoothly.
Active Feedback sensing Technology
If the tool body suddenly rotates at the specified accel
-
eration due to the drill bit locking, etc., the motor is
forcibly stopped to reduce the burden on the wrist.
NOTE:
The active feedback sensing technology func
-
tion does not work if the acceleration does not reach
the specified one.
NOTE:
The active feedback sensing technology
function also actuates just when the bit simply swung
at the specified acceleration in any operation.
In this case, release the switch trigger, and then pull
the switch trigger to restart the tool.
