Hilti TE106 Operating Instructions Manual page 28

NOTE
The chisel can be adjusted to 12 different positions
(in 30° increments). This ensures that flat chisels and
shaped chisels can always be set to the optimum
working position.
7.2.1.1 Chisel position adjustment
en
CAUTION
Do not operate the power tool with the switch set to
this position.
1. Turn the function selector switch until it engages
in the "Chisel adjustment" position. Do not oper-
ate the function selector switch while the motor
is running.
2. Rotate the chisel to the desired position.
7.2.1.2 Locking the chisel

7.2.1.3 Chiseling

2. Position the tip of the chisel at the point where
chiseling is to begin.
3. Press the control switch fully.
7.2.2 Operation with the needle adapter
(optional)
CAUTION
The needle adaptor is for use only with the TE 106.
NOTE
Working at low temperatures: The hammering mech-
anism works only when the power tool has reached a
minimum operating temperature. Bring the chisel into
contact with the base material and allow the power
tool to run under no load until the minimum operat-
ing temperature is reached. If necessary, repeat this
procedure until the hammering mechanism begins to
operate.
NOTE
Apply moderate pressure. Insufficient pressure re-
duces the life of the part. It must always remain in
contact with the working surface.
