Safety warnings about connecting
lanyard (tether strap) to the hook
Safety warnings specific for use at height
Read all safety warnings and instructions. Failure to follow
the warnings and instructions may result in serious injury.
1. Always keep the tool tethered when working
"at height". Maximum lanyard length is 2 m.
The maximum permissible fall height for lan-
yard (tether strap) must not exceed 2 m.
2. Use only with lanyards appropriate for this tool
type and rated for at least 8.0 kg.
Do not anchor the tool lanyard to anything on
3.
your body or on movable components. Anchor
the tool lanyard to a rigid structure that can
withstand the forces of a dropped tool.
4. Make sure the lanyard is properly secured at
each end prior to use.
Inspect the tool and lanyard before each use
5.
for damage and proper function (including
fabric and stitching). Do not use if damaged or
not functioning properly.
Do not wrap lanyards around or allow them to
6.
come in contact with sharp or rough edges.
Fasten the other end of the lanyard outside the
7.
working area so that a falling tool is held securely.
8. Attach the lanyard so that the tool will move
away from the operator if it falls. Dropped tools
will swing on the lanyard, which could cause injury
or loss of balance.
Do not use near moving parts or running
9.
machinery. Failure to do so may result in a crush
or entanglement hazard.
10. Do not carry the tool by the attachment device
or the lanyard.
11. Only transfer the tool between your hands
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.
16. In the event the tool is dropped, it must be tagged
and removed from service, and should be inspected
by a Makita Factory or Authorized Service Center.
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.
• 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 accel-
eration 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.
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 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 with its retaining projections fully
engaged by the positioning recesses on the gear
housing.
To install the side grip, follow the steps below.
1. Loosen the thumb screw on the side grip. Then install
the side grip over the barrel neck of the gear housing.

5. Positioning recess
The attachment ring can be enlarged by pressing the
thumb screw down so that the ring is easily and securely
engaged over the barrel neck of the gear housing.

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.
