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
rotation speed regardless of load conditions.
•
Active Feedback sensing Technology (For
HR001G/HR002G)
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.
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.
To install the side grip, follow the steps below.
1.

3.
Tighten the thumb screw to secure the grip. The
grip can be fixed at desired angle.
Grease
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 or removing drill bit
Clean the shank end of the drill bit and apply grease
before installing the drill bit.

Chisel angle (when chipping,
scaling or demolishing)
The chisel can be secured at the desired angle. To
change the chisel angle, rotate the action mode chang-
ing knob to the O symbol. Turn the chisel to the desired
angle.

Action mode changing knob
Rotate the action mode changing knob to the sym-
bol. Then make sure that the chisel is securely held in
place by turning it slightly.
Depth gauge
The depth gauge is convenient for drilling holes of
uniform depth.
Press and hold the lock button, and then insert the
depth gauge into the hex hole. Make sure that the
toothed side of the depth gauge faces the marking.
