7.2.3 Active Torque Control (TE 80‑ATC/
TE 70‑ATC)
In addition to the mechanical safety slip clutch, the power
tool is also equipped with the Active Torque Control sys-
tem. This system offers additional comfort while drilling
as it causes rapid shutdown upon sudden rotation of
the power tool about the drill bit axis, e.g. when the
drill bit sticks due to hitting a rebar or when the drill bit
is tilted unintentionally. When the torque control system
has become activated, the power tool can be restarted by
releasing the control switch and re-engaging it after the
motor has stopped rotating (a "click" indicates that the
power tool is again ready for operation). Always choose a
working position in which the electric tool is free to rotate
in a counterclockwise direction (as seen by the operator).
If this rotation is not possible, the ATC system will be
unable to react.
7.2.4 Chiseling 7
NOTE
The chisel can be adjusted to 24 different positions
(in 15° increments). This ensures that flat chisels and
shaped chisels can always be set to the optimum working
position.
CAUTION
Do not operate the power tool when the selector switch
is set to "Chisel adjustment".
1. To adjust the position of the chisel, turn the func-
tion selector switch until it engages in the "Chisel
adjustment" position.
2. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
3. Rotate the chisel to the desired position.
4. To lock the chisel in the desired position, turn
the function selector switch until it engages in the
"Chiseling" position. Do not operate the function
selector switch while the motor is running.
5. To begin chiseling, plug the power tool's supply
cord into the power outlet.
6. Set the desired chiseling power (optional).
NOTE After connecting the supply cord to the elec-
tric supply, the power tool is always set to full
chiseling power.
NOTE To set the power tool to reduced (50%)
chiseling power, press the "reduced power" button.
The chiseling power LED then lights. To reselect full
chiseling power, press the "reduced power" button
again.
7. Position the tip of the chisel at the point where
chiseling is to begin.
8. Press the control switch fully.
7.2.5 Drilling without hammering
Drilling without hammering is possible when drill bits with
a special connection end are used. Drill bits of this kind
are available from Hilti. For example, when the keyless
quick-release chuck is fitted, smooth-shank drill bits for
wood or steel can be used to drill without hammering.
The function selector switch must be set to the "Hammer
drilling" position when the power tool is used in this way.
7.2.6 Control switch lock 8
When chiseling, the control switch can be locked in the
"on" position.
1. Push the control switch lock above the grip forward.
2. Press the control switch fully.
The power tool then operates in sustained mode.
3. To cancel sustained operating mode, slide the con-
trol switch lock to the rear.
The power tool then switches off.
7.2.7 Mixing
1. Turn the function selector switch until it engages in
the "Hammer drilling" position.
2. Insert the quick-release chuck in the power tool's
chuck.
3. Insert the mixing paddle.
4. Check that the insert tool has engaged correctly by
pulling it.
5. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
6. Plug the supply cord into the power outlet.
7. Position the mixing paddle in the container holding
the substance to be mixed.
8. To begin mixing, press the control switch slowly.
9. Press the control switch fully to continue working at
full power.
10. Guide the mixing paddle carefully in order to avoid
splashing and spillage.
