Care And Maintenance - Hilti TE 1000-AVR Original Operating Instructions

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.
7.3 Chiseling tips
7.3.1 Starting chiseling 7
Position the tip of the chisel approx. 80-100 mm from the
edge of the workpiece.
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.

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.
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.
8.3 Service indicator
NOTE
The power tool is equipped with a service indicator.
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 releas-
able 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.
The outer casing of the power tool is made from impact-
resistant plastic. The grips have a synthetic rubber cov-
ering.
Never operate the power tool when the ventilation slots
are blocked. Clean the ventilation slots carefully using
a dry brush. Do not permit foreign objects to enter the
interior of the power tool. Clean the outside of the power
tool at regular intervals with a slightly damp cloth. Do
not use a spray, steam pressure cleaning equipment or
running water for cleaning. This may negatively affect the
electrical safety of the power tool.
