Use a vice or clamp to secure loose workpieces.
5.3 General safety precautions
●
Never leave the tool unsupervised.
●
The side handle must always be fitted when the tool is
in use.
●
The tool is for hand-held use only.
●
Hold the side-handle securely at the end furthest from
the tool.
●
Keep the tool, especially its grip surfaces, clean and
free from oil and grease.
●
Always hold the tool securely, with both hands on the
grips provided.
●
In the event of the drill bit sticking, the tool will be
deflected to the side (rotary movement).
TE 56-ATC: When drilling in the corner of a room, the
ATC system cannot react to this deflection in time.
●
The tool is not suitable for use in atmospheres where
there is a risk of explosion.
●
When not in use, the tool must be stored in a dry place,
locked up or out of reach of children.
●
Avoid long periods of work with exposure to strong
vibration.
●
Avoid unintentional starting. Do not carry the tool with
your finger on the on/off switch.
●
Disconnect the supply cord plug from the socket when
the tool is not in use (e.g. during breaks, before main-
tenance and before changing insert tools).
●
Take care of your insert tools. You will be able to work
more efficiently and more safely if the insert tools are
kept sharp and clean. Observe instructions on care and
maintenance and on changing insert tools.
5.3.1 Mechanical
●
Observe the instructions concerning care and main-
tenance and replacement of insert tools in good time.
●
Ensure that the insert tools used are equipped with the
correct connection end system and that they are prop-
erly fitted and secured in the chuck.
5.3.2 Electrical
●
Check the condition of the tool including the supply
cord and extension cord as well as the plug connec-
tions. Do not operate the tool if damage is found, if the
5.1 Basic information concerning safety
In addition to the information relevant to safety given
in each of the sections of these operating instructions,
the following points must be strictly observed at all
times.
●
The tool may be operated only when connected to a
power supply providing a voltage and frequency in
compliance with the information given on its rating
plate.
●
Do not expose the tool to rain or snow, do not use it in
damp or wet areas or in the vicinity of inflammable liq-
uids or gasses.
●
Changes or modifications to the tool are not permissible.
●
To avoid the risk of injury, use only original Hilti acces-
sories and additional equipment.
●
Do not overload the tool. It will work more efficiently
and more safely within its intended performance range.
●
Observe the information printed in the operating instruc-
tions concerning operation, care and maintenance. The
tool and its ancillary equipment may present hazards
when used incorrectly by untrained personnel or when
used not as directed.
5.2 Take the necessary precautions to make the
workplace safe
●
Ensure that the workplace is well lit.
●
Ensure that the workplace is well ventilated.
●
Keep the working area tidy. Objects which could cause
injury should be removed from the working area.
●
When working, keep other persons, particularly chil-
dren, outside the range of the tool.
●

●
To avoid tripping and falling when working, always lead
the supply cord, extension cord and extraction hose
away to the rear.
●
Concealed electric cables or gas and water pipes pre-
sent a serious hazard if damaged while you are work-
ing. Accordingly, check the area in which you are work-
ing beforehand (e.g. using a metal detector). Avoid
contact between your body and earthed / grounded
objects, such as pipes or radiators. External metal parts
