while you are properly balanced.
12. Do not attach lanyards to the tool in a way that
keeps switches or trigger-lock (if supplied)
from operating properly.
13. Avoid getting tangled in the lanyard.
14. Keep lanyard away from the drilling area of the
tool.
15. Use a locking carabiner (multi-action and
screw gate type). Do not use single action
spring clip carabiners.

tagged and removed from service, and should
be inspected by a Makita Factory or Authorized
Service Center.

Torque limiter

As soon as the torque limiter actuates,
NOTICE:
switch off the tool immediately. This will help pre-
vent premature wear of the tool.
Drill bits such as hole saw, which tend
NOTICE:
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.
• Electric brake
This tool is equipped with an electric brake. If the
tool consistently fails to quickly cease to function
after the switch trigger is released, have the tool
serviced at a Makita service center.
• Constant speed control
The speed control function provides the constant
rotation speed regardless of load conditions.
• Active Feedback sensing Technology
If the tool is swung at the predetermined accelera-
tion during operation, the motor is forcibly stopped
to reduce the burden on the wrist.
NOTE: This function does not work if the acceleration
does not reach the predetermined one when the tool
is swung.
NOTE: If the bit is swung at the predetermined
acceleration during chipping, scaling, or demolishing,
the motor is forcibly stopped. In this case, release
the switch trigger, and then pull the switch trigger to
restart the tool.

2. Tighten the thumb screw to secure the grip at your
desired angle.
Grease
Optional accessory
Coat the shank end of the drill bit beforehand with a
small amount of grease (about 0.5 - 1 g).
This chuck lubrication assures smooth action and lon-
ger service life.
Installing and removing drill bit
Clean the shank end of the drill bit and apply grease
before installing the drill bit.
► Fig.15: 1. Shank end 2. Grease
Place the shank end of the drill bit into the chuck, and
insert it further into the chuck while hand-turning the
drill bit so the shank end well fits into the chuck slot and
becomes fully engaged.
Having installed the drill bit, try pulling it back to ensure
it is securely held in place.
