transformers
Please refer to section 2 "Description".

7 Operation

CAUTION
In the event of the drill bit sticking, the power tool will
pivot about its own axis. Always use the power tool with
the side handle fitted and hold it securely with both
hands so that the resulting opposing force causes
the slip clutch to release in the event of the drill bit
sticking. Use clamps or a vice to hold the workpiece
securely.
7.1 Active Torque Control 3
In addition to the mechanical slip clutch, the tool is also
equipped with ATC (Active Torque Control). This system
offers additional comfort while drilling as it causes rapid
shutdown upon sudden rotation of the power tool about
the drill bit axis, e.g. when the drill bit sticks due to
hitting a rebar or when the drill bit is tilted unintention-
ally. If the ATC system has triggered, restart the power
tool by releasing the control switch and then pressing
it again. Always choose a working position in which the
electric tool, when turning clockwise, is free to rotate
in a counterclockwise direction (as seen by the oper-
ator). In counterclockwise rotation, the tool reacts and
turns clockwise. If rotation is not possible, active torque
control cannot react.
7.2 Preparing for use
7.2.1 Adjusting the depth gauge 4
1. Release the side handle clamping band by turning
the handle counterclockwise.
2. Pivot the side handle into the desired position.
3. Adjust the depth gauge to the desired drilling depth
"X".
4. Tighten the side handle securely by turning it clock-
wise.
7.2.2 Fitting the insert tool 5
1. Disconnect the supply cord plug from the power
outlet.
2. Check that the connection end of the insert tool is
clean and lightly greased. Clean it and grease it if
necessary.
3. Check that the sealing lip of the dust shield is
clean and in good condition. Clean the dust shield if
necessary or replace it if the sealing lip is damaged.
6.3 Dust removal (TE DRS‑S)
A DRS dust removal head can be fitted to the depth
gauge of the side handle. Drilling dust and fragments can
then be removed by a vacuum cleaner. For further inform-
ation on operation and use of the dust removal system,
please refer to the separate operating instructions for the
TE DRS‑S.
4. Push the insert tool into the chuck and rotate it while
applying slight pressure until it engages in the guide
grooves.
5. Push the insert tool further into the chuck until it is
heard to engage.
6. Check that the insert tool has engaged correctly by
pulling it.
7.2.3 Removing the insert tool 6
CAUTION
Wear protective gloves when changing insert tools as
the insert tools get hot during use.
1. Disconnect the supply cord plug from the power
outlet.
2. Open the chuck by pulling back the chuck release
sleeve.
3. Pull the insert tool out of the chuck.
7.2.4 Removing the chuck 7
CAUTION
Remove the depth gauge from the side handle in order
to avoid injury.
1. Disconnect the supply cord plug from the power
outlet.
2. Pull the chuck sleeve forward and hold it securely.
3. Remove the chuck by pulling it away from the power
tool.
7.2.5 Fitting the chuck 8
CAUTION
Remove the depth gauge from the side handle in order
to avoid injury.
1. Disconnect the supply cord plug from the power
outlet.
2. Grip the chuck sleeve, pull it forward and hold it
securely in this position.
3. Slide the chuck onto the guide tube from the front
and then release the sleeve.
4. Rotate the chuck until it is heard to engage.
