feature, it can be unlocked and made ready for operation
only through use of the corresponding TPS key.
7.2.1.1 Unlocking the power tool 5
1. Plug the supply cord into the power outlet. The
yellow theft protection indicator LED blinks. The
power tool is now ready to receive the signal from
the TPS key.
en
2. Hold the TPS key or the TPS watch strap buckle
against the lock symbol. The power tool is unlocked
as soon as the yellow theft protection indicator LED
no longer lights.
NOTE If, for example, the electric supply is briefly
interrupted due to a power failure or disconnected
when moving to a different workplace, the power
tool remains ready for operation for approx. 20
minutes. In the event of a longer interruption, the
TPS key must be used again to unlock the power
tool.
7.2.1.2 Activation of the theft protection system for
the power tool
NOTE
Further detailed information on activation and use of the
theft protection system can be found in the operating
instructions for the theft protection system.
7.2.2 Hammer drilling 6
NOTE
Working at low temperatures: The hammering mech-
anism works only when the power tool has reached a
minimum operating temperature. Bring the tip of the drill
bit or chisel into contact with the workpiece and allow
the power tool to run under no load until it reaches
the minimum operating temperature. If necessary, repeat
this procedure until the hammering mechanism begins to
operate.
1. Turn the function selector switch until it engages in
the "Hammer drilling" position. Do not operate the
function selector switch while the motor is running.
2. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
3. Plug the supply cord into the power outlet.
4. Set the drilling power.
NOTE After connecting the supply cord to the elec-
tric supply, the power tool is always set to full drilling
power.
NOTE To set the power tool to reduced (50%) drilling
power, press the reduced-power button. The drilling
power LED then lights. To reselect full drilling power,
press the reduced-power button again.
5. Position the power tool and drill bit at the point
where the hole is to be drilled.
6. Press the control switch slowly (drill at a low speed
until the drill bit centers itself in the hole).
7. Press the control switch fully to continue working at
full power.
8. Do not apply excessive pressure. This will not in-
crease the power tool's hammering performance.
Lower pressure extends the life of the insert tool.

9. Reduce drilling speed shortly before breaking
through in order to avoid spalling.
7.2.3 Active Torque Control (TE 60‑ATC /
TE 60T‑ATC)
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 unintentionally. When the
torque control system has become activated, the power
tool can be restarted by releasing the control switch and
re-engaging it after the motor has stopped rotating (a
"click" indicates that the power tool is again ready for
operation). Always choose a working position in which
the electric tool is free to rotate in a counterclockwise
direction (as seen by the operator). If this rotation is not
possible, the ATC system will be unable to react.
7.2.4 Chiseling 7
NOTE
The chisel can be adjusted to 24 different positions
(in 15° increments). This ensures that flat chisels and
shaped chisels can always be set to the optimum working
position.
CAUTION
Do not operate the power tool when the selector switch
is set to "Chisel adjustment".
1. To adjust the position of the chisel, turn the func-
tion selector switch until it engages in the "Chisel
adjustment" position.
2. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
3. Rotate the chisel to the desired position.
4. To lock the chisel in the desired position, turn
the function selector switch until it engages in the
"Chiseling" position. Do not operate the function
selector switch while the motor is running.
5. To begin chiseling, plug the power tool's supply
cord into the power outlet.
6. Set the desired chisel position.
NOTE After connecting the supply cord to the elec-
tric supply, the power tool is always set to full
chiseling power.
NOTE To set the power tool to reduced (50%)
chiseling power, press the reduced-power button.
The chiseling power LED then lights. To reselect full
chiseling power, press the reduced-power button
again.
7. Position the tip of the chisel at the point where
chiseling is to begin.
8. Press the control switch fully.
