7.2.1 Chiseling 6
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 operating tem-
perature is reached. If necessary, repeat this procedure
until the hammering mechanism begins to operate.
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
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 operate the
function selector switch while the motor is running.
2. Rotate the chisel to the desired position.
7.2.1.2 Locking the chisel
Turn the function selector switch to the "Chiseling" posi-
tion and rotate the chisel until it engages. Do not operate
the function selector switch while the motor is running.
7.2.1.3 Chiseling
1. Plug the supply cord into the power outlet.
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 300-
AVR.
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 operating tem-
perature is reached. If necessary, repeat this procedure
until the hammering mechanism begins to operate.
NOTE
Apply moderate pressure. Insufficient pressure reduces
the life of the part. It must always remain in contact with
the working surface.
