5 Safety instructions

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.

5.1 Intended use

a) The tool and its ancillary equipment may present
hazards when used incorrectly by untrained per-
sonnel or when used not as directed.
b) To avoid the risk of injury, use only genuine Hilti
accessories and additional equipment.
c) Modification of the tool or tampering with its parts
is not permissible.
d) Observe the information printed in the operat-
ing instructions concerning operation, care and
maintenance.
e) Do not render safety devices ineffective and do
not remove information and warning notices.
f) Check the condition of the tool before use. If the
tool is found to be damaged, have it repaired at a
Hilti Service Center.
g) In particularly critical situations where measurements
have safety and structural stability implications, al-
ways check results by removing material from the
surface of the structure and physically checking the
position, depth and diameter of reinforcement at key
positions.
h) When drilling at or near to a bar indicated by the sys-
tem, never drill deeper than the bar depth indicated.
5.2 Proper organization of the workplace
a) Keep the workplace tidy. Objects which could
cause injury should be removed from the work-
ing area. Untidiness at the workplace can lead to
accidents.
b) Keep other persons, especially children, away
from the area in which the work is being carried
out.
c) Wear non-skid shoes.
d) Avoid unfavorable body positions when working
from ladders. Make sure you work from a safe
stance and stay in balance at all times.
e) Only use the tool within the defined limits.
f) Check with a qualified person that it is safe to drill at
a specified point before beginning drilling.
g) Do not use the tool where there is a risk of fire or
explosion.

h) Make sure that the toolbox is properly secured during
transport and does not present a risk of injury.

5.3 Electromagnetic compatibility

Although the tool complies with the strict requirements of
the applicable directives, Hilti cannot entirely rule out the
possibility of interference to the tool caused by powerful
electromagnetic radiation, leading to incorrect operation.
Accuracy must be checked by taking measurements by
other means when working under such conditions or
if you are unsure. Likewise, Hilti cannot rule out the
possibility of interference with other devices (e.g. aircraft
navigation equipment).

5.4 General safety precautions

5.4.1 Mechanical safety precautions
a) Check the tool for damage before use. If the tool
is found to be damaged, have it repaired at a Hilti
Service Center.
b) You must check the accuracy of the tool after it
has been dropped or subjected to other mechan-
ical stresses.
c) When the tool is brought into a warm environment
from very cold conditions, or vice-versa, allow it
to become acclimatized before use.
d) Although the tool is protected against the entry of
moisture, it should be wiped dry before being put
away in its transport container.

5.4.2 Electrical safety precautions

a) Avoid short circuiting the battery terminals. Check
that the terminals on the battery pack and in the tool
are free from foreign objects before inserting the
battery pack. Short circuiting the battery terminals
presents a risk of fire, explosion and chemical burns.
b) Make sure that the outer surfaces of the battery
pack are clean and dry before inserting it in the
charger. Observe the operating instructions for
the charger.
c) Use only the battery pack specified in these operating
instructions.
d) Batteries that have reached the end of their life must
be disposed of safely and correctly to avoid environ-
mental pollution.
e) Remove the battery pack before transporting the tool
or storing it for a long period of time. Inspect the
battery pack for any signs of leakage or damage
before reusing it.
f) To avoid pollution of the environment, the tool
must be disposed of in accordance with the cur-
