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 flashes. The
power tool is now ready to receive the signal from
the TPS key.
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
is no longer lit.
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.

7.2.2 Chiseling
7.2.2.1 Working at low temperatures
NOTE
The power tool must reach a minimum operating tem-
perature before the hammering mechanism begins to
operate.
Bring the power tool to the minimum operating temperat-
ure by switching it on and allowing it to run and warm up.
Bring the tip of the chisel into contact with the work sur-
face at regular intervals (approx. every 30 sec.) to check
whether the hammering mechanism has begun to oper-
ate. Repeat the procedure if the hammering mechanism
does not begin to operate.
NOTE
As starting is electronically controlled, the power tool's
starting characteristics may be different in cold condi-
tions.
7.2.2.2 Switching on
1. Plug the mains plug of the supply cord into the
power outlet.
2. Press the on / off switch.
7.2.2.3 Adjusting chiseling power 6
Chiseling power can be reduced to approx. 70% by
pressing the power level selector switch. The power level
LED then lights up, indicating reduced power.
NOTE
Chiseling power can be adjusted only when the power
tool is switched on and ready for use. To reselect full
chiseling power, press the chiseling power level selector
switch again. Switching off and then on again also causes
the power tool to return to full chiseling power.
7.2.2.4 Switching off
1. Press the on / off switch.
2. Disconnect the mains plug from the power outlet.
7.3 Chiseling tips
7.3.1 Contact pressure
If inadequate pressure is applied, the chisel will jump
around uncontrollably.
Application of excessive pressure will result in a loss of
chiseling performance.
8.2 Care of the power tool
CAUTION
Keep the power tool, especially its grip surfaces,
clean and free from oil and grease. Do not use clean-
ing agents which contain silicone.
