Preparation For Use; Operation - Hilti TE 76 Mode D'emploi

Preparation for use

It is essential that the safety precautions print-
ed in these operating instructions are read and observed.
The supply voltage must correspond to the infor-
mation on the type plate.
If extension cords are used: Only extension cords
of a type approved for the intended use and of adequate
cross section may be used. Failure to observe this point
may result in reduced performance of the tool and over-
heating of the cord. Damaged extension cords must be
replaced. The recommended cross-sections and max.
length for extension cords are:
Conductor cross-section
Mains mm
voltage 1.5 2.0
100 V 20 m 30 m

220–240 V 50 m 75 m 100 m 125 m –
Do not use 1.25 mm 2 and 16 AWG extension cords.
Use only insert tools with TE-Y connection end.
Don't exert excessive pressure on the tool. This will not
increase its hammering power.
At low temperatures: The tool requires to reach a mini-
mum operating temperature before the hammering
mechanism begins to operate. Switch on the tool and
position the tip of the drill bit or chisel on the work sur-
face. While the tool is running, apply light pressure briefly
and repeatedly until the hammering mechanism begins
to operate.

Operation

Operating from generators and transformers
This tool can be used on a generator and jobsite trans-
formers if it meets the following requirements:
– AC output 2600 W minimum; 24 A minimum
– 120 V AC nominal; min. 102 V, max. 132 V under all
conditions
– frequency 50–60 Hz; never to exceed 65 Hz
– high dynamic automatic voltage regulator
Do not use other power tools on the generator/
transformer at the same time. Switching other tools
on/off can cause undervoltage and/or overvoltage spikes
which could damage the tool.
Inserting the insert tool
a) Unplug the supply cord from the electrical sock-
et to prevent unintentional starting.
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 yel-
low 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
position (
c) Select the desired drilling power (II = full power,
I = half power)
(e.g. perforated brick), drilling at the half-power set-
ting can be of advantage. This may improve the qual-
ity of the hole drilled.
