Rotation with hammering
For drilling in concrete, masonry, etc., rotate the action
mode changing knob to the
bide-tipped drill bit.

Hammering only
For chipping, scaling or demolition operations, rotate
the action mode changing knob to the
bull point, cold chisel, scaling chisel, etc.

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.
Electric brake
This tool is equipped with an electric brake. If the tool
consistently fails to quickly stop after the switch trigger
is released, have the tool serviced at a Makita service
center.

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.
Side handle
► Fig.8
CAUTION:
Use the side handle only when
chipping, scaling or demolishing. Do not use it
when drilling in concrete, masonry, etc. The tool
cannot be held properly with this side handle when
drilling.
► Fig.9: 1. Side handle 2. Clamp nut
The side handle can be swung in a vertical direction
and secured at any desired position. It can also be
adjusted at eight steps back and forth in a horizontal
direction. Loosen the clamp nut to swing the side han-
dle to a desired position, and then tighten the clamp nut
securely.
Side grip (auxiliary handle)
CAUTION:
Always use the side grip to ensure
safe operation.
CAUTION:
After installing or adjusting the
side grip, make sure that the side grip is firmly
secured.
The side grip can be swung, allowing easy handling of
the tool in any position. Loosen the side grip by turning
it counterclockwise, swing it to the desired position and
then tighten it by turning clockwise.

Installing or removing drill bit
Grease
Clean the shank end of the bit and apply grease before
installing the bit.
Coat the shank end of the bit beforehand with a small
amount of grease (about 0.5 - 1 g). This chuck lubrica-
tion assures smooth action and longer service life.
► Fig.11: 1. Shank end 2. Grease
Insert the drill bit into the tool. Turn the drill bit and push
it in until it engages.
After installing the drill bit, always make sure that the
drill bit is securely held in place by trying to pull it out.
► Fig.12: 1. Drill bit
To remove the drill bit, pull the chuck cover down all the
way and pull the drill bit out.
