7.2.1 Chiseling
7.2.1.1 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 tempera-
ture 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.
7.2.1.2 Switching on
1. Plug the supply cord into the power outlet.
2. Press the on / off switch.
7.2.1.3 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.
7.2.1.4 Switching off
1. Press the on / off switch.
2. Disconnect the supply cord plug from the power
outlet.

8 Care and maintenance

CAUTION
Disconnect the mains plug from the power outlet.
8.1 Care of insert tools
Clean off dirt and dust deposits adhering to the insert
tools and protect them from corrosion by wiping the
insert tools from time to time with an oil-soaked rag.
7.3 Chiseling tips
7.3.1 Starting chiseling 7
Bring the tip of the chisel into contact with the workpiece
about 3¹⁄₈" - 4" (80 - 100 mm) from its edge.
7.3.2 Reinforcing bars 8
Always guide the tip of the chisel toward the edge of the
workpiece, not toward reinforcing bars.
7.3.3 Chiseling direction 9
1. Begin with the chisel positioned at an angle of 70°
to 80° to the concrete surface, with the tip of the
chisel pointing toward the edge of the workpiece.
2. Break material away by increasing the angle to ap-
prox. 90° as the chisel penetrates.
7.3.4 Self-sharpening process 10
The chisel should be rotated at regular intervals as even
wear assists the self-sharpening process.
7.3.5 Chiseling depth 11
The polygon chisel design ensures that material is broken
up even when the chisel penetrates to great depths.
7.3.6 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.
7.4 Disconnecting the supply cord from the power
tool 12
CAUTION
Disconnect the supply cord plug from the electric
power outlet after finishing the work and before dis-
connecting the releasable supply cord connector.
1. Disconnect the supply cord plug from the power
outlet.
2. Pull the locking ring back and turn the keyed re-
leasable connector in a counterclockwise direction
as far as it will go.
3. Pull the supply cord connector out of the power tool.
4. Place the supply cord in the transport box.
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.
