Adjusting the drilling depth
Slide the depth adjustment button to the desired posi-
tion while pressing it. The distance (A) is the drilling
depth.
► Fig.11: 1. Depth adjustment button
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.
Hook
CAUTION:
Never hook the tool at high loca-
tion or on potentially unstable surface.
For HR2663
► Fig.12: 1. Hook
The hook is convenient for temporarily hanging the tool.
To use the hook, simply lift up hook until it snaps into
the open position. When not in use, always lower hook
until it snaps into the closed position.
ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and unplugged 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.
Install the side grip so that the grooves on the grip fit in
the protrusions on the tool barrel. Turn the grip clock-
wise to secure it. 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.
► Fig.14: 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.15: 1. Drill bit
To remove the drill bit, pull the chuck cover down all the
way and pull the drill bit out.

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.
► Fig.17: 1. Action mode changing knob
Rotate the action mode changing knob to the
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. Loosen the side grip and insert the depth
gauge into the hole on the side grip. Adjust the depth
gauge to the desired depth and tighten the side grip
firmly.
► Fig.18: 1. Hole 2. Depth gauge
NOTE: Make sure that the depth gauge does not
touch the main body of the tool when attaching it.
Installing or removing dust
collection system
To remove the dust collection system, pull the tool while
pressing the lock-off button. To install it, insert the tool
into the dust collection system all the way until it locks in
place with a little click.
► Fig.19: 1. Lock-off button
Dust cup
Optional accessory
Use the dust cup to prevent dust from falling over the
tool and on yourself when performing overhead drilling
operations. Attach the dust cup to the bit as shown in
the figure. The size of bits which the dust cup can be
attached to is as follows.
