7.2 Operation
CAUTION
Working on the material may cause it to splinter. Wear
en
eye protection and protective gloves. Wear breathing
protection if no dust removal system is used. Splin-
tering material presents a risk of injury to the eyes and
body.
CAUTION
The work generates noise. Wear ear protectors. Expos-
ure to noise can cause hearing loss.
CAUTION
Switch the power tool on only after bringing it into the
working position.
CAUTION
Do not operate the function selector switch while the
motor is running.
7.2.1 TPS theft protection system (optional)
NOTE
The power tool may be equipped with the optional theft
protection system. If the power tool is equipped with this
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.
2. Hold the TPS key 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
22
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.
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 desired drilling power (optional).
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 damage to the surface at
the rear side.
7.2.3 Active Torque Control (TE 80‑ATC/
TE 70‑ATC)
In addition to the mechanical safety slip clutch, the power
tool is also equipped with the Active Torque Control sys-
tem. 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".
