b) Check that the connection end of the insert tool is
clean and lightly greased. Clean it and grease it if nec-
essary . Check that the sealing lip of the dust shield
is clean. Wipe it off if necessary. Take care to ensure
that no drilling dust finds its way into the interior of
the chuck. The dust shield must be replaced when
the sealing lip is damaged. Please refer to the section
on care and maintenance.
c) Insert the insert tool in the chuck and rotate it while
applying slight pressure until it engages in the guide
grooves.
d) Push the insert tool in further until it is heard to engage.
Check that the insert tool has engaged correctly by
pulling on it.
Removing the insert tool
a) Unplug the supply cord from the electrical sock-
et to prevent unintentional starting.
b) Pull back the chuck locking sleeve and pull out the
insert tool .
Wear protective gloves. The insert tool
may be very hot after long periods of use.
Drilling
Operation
Activating the tool (theft protection system)
(Optional – not available with all versions.)
Further detailed information about activation and use of
this optional feature can be found in the separate oper-
ating instructions for the theft protection system.
1. Plug the supply cord into the power outlet. The yellow
theft protection indicator lamp blinks. The tool is now
ready to receive the signal from the activation key.
2. Hold the activation key close to the lock symbol on
the tool. The tool is activated as soon as the theft pro-
tection indicator lamp no longer lights.
-NOTE-
In the event of interruption of the electric supply to the
tool, e.g. brief disconnection to move to a different work-
place, the tool remains operational for approx. 20 min-
utes. After a longer interruption, the tool must be reac-
tivated by way of the activation key.
Hammer drilling
a) Insert drill bit into the chuck.
b) Move the selector switch to the hammer drilling posi-
tion ( ) until it engages
c) Select the desired drilling power (II = full power, I =
half power) . When drilling in brittle materials (e.g.

f) Bring the tip of the drill bit into contact with the work
g) Press the control switch fully and continue drilling at
Active Torque Control (only TE 76-ATC / TE 76P-ATC)
The TE76-ATC / TE 76P-ATC is equipped with the Active
Torque Control system in addition to the mechanical
torque limiting clutch. This system offers additional pro-
tection while drilling by rapid shutdown upon uncon-
trolled rotation in the axis of the drill bit, e. g. when the
drill bit jams due to hitting rebar or when the insert tool
is tilted unintentionally.
When the ATC system has become activated, the tool
can be restarted by releasing the control switch and re-
engaging it after the the motor has stopped rotating
("click"-sound signals readiness for use).
Always choose a working position in which the electric
tool is free to rotate
(as seen by the operator). If this is not possible, the ATC
system cannot react.
Drilling using the depth gauge (accessory)
We recommend the use of the depth gauge for drilling
holes to the exact depth required. The depth gauge rod
is offset in order to reduce deviations caused by tilting
the tool and to make it easier to adjust the drilling depth
Assembly
of the power tool so that the two positioning lugs engage
in the depressions for the flange screws. Press the depth
gauge on to the tool until the two rear retaining lugs
engage in the tool casing. Insert the depth gauge rod
into the depth gauge from the front, with the offset end
towards the front of the tool.
Adjusting drilling depth
to the required drilling depth. Adjust the front end of the
depth gauge rod until it is approx. 10 mm (
drill bit and then tighten the locking screw.
After use, remove the depth gauge and store it in the
toolbox.
Drilling without hammering action
Drilling without hammering action is possible with insert
tools with a special connection end. Insert tools of this
kind are available in the Hilti insert tool programme.
