4 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.
The tool is designed to detect ferrous metals (steel re-
bars) and non-ferrous metals (copper and aluminium)
en
in concrete, brick, drywall and under plaster surfaces
in accordance with the information provided in the
technical data section.

4.1 Basic information concerning safety

a) Do not render safety devices ineffective and do
not remove information and warning notices.
b) Keep children away from the tool.
c) Check that the tool functions correctly each time
before use.
d) Check the display after switching the tool on. The
display should show the Hilti logo, the tool model
designation and version. The tool then carries out a
brief self-test, after which the standard settings or
the previously saved settings are displayed.
e) Check to ensure that the tool is able to calibrate
itself after switching on.
f) Operation of the tool in the proximity of pregnant
women is not permissible.
g) Rapidly changing detection conditions may lead to
inaccurate readings.
h) Use the tool only within the specified conditions.
Do not use the tool on materials containing items
such as tensioning cables or stainless steel ob-
jects.
Do not use the tool in the proximity of medical
i)
instruments and appliances.
j) Do not drill at positions where the tool has located
an object.
k) The warnings shown in the display must always
be observed.
Do not use the tool for quality control inspections.
l)
m) Do not use the tool in the proximity of sources of
electromagnetic interference (e.g. electric break-
ers in operation).
n) Take the influences of the surrounding area into
account. Do not use the tool where there is a risk
of fire or explosion.
o) Use of the tool in the proximity of persons with a
cardiac pacemaker is not permissible.
p) Make sure that the display area can be easily
read (e.g. do not touch the display area with the
fingers, keep the display area clean).
q) Do not use the tool if it is defective.
r) Always keep the detection area clean.
s) Always check how the tool is set before using it.
t) The accuracy of the tool is influenced by the base
material. If the tool is unable to calibrate itself cor-
rectly, small measurement errors may result.
u) When the tool is unable to calibrate itself automatic-
ally, a warning appears in the display.

4.2 Proper organization of the workplace
a) Avoid unfavorable body positions when working
on ladders or scaffolding. Make sure you work
from a safe stance and stay in balance at all
times.
b) When the tool is brought into a warm environment
from very cold conditions, or vice-versa, allow it
to become acclimatized before use.
c) Use the tool only within its specified limits.
d) Observe the accident prevention regulations ap-
plicable in your country.
4.3 Electromagnetic compatibility
Although the tool complies with the strict requirements of
the applicable directives, Hilti cannot entirely rule out the
possibility of the tool being subject to interference caused
by powerful electromagnetic radiation, leading to incor-
rect operation. Check the accuracy of the tool 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). The tool complies with the
requirements of class A; The possibility of interference
occurring in a domestic environment cannot be excluded.
4.4 General safety instructions
a) Check the condition of the tool before use. If the
tool is found to be damaged, have it repaired at a
Hilti service center.
b) The user must check the accuracy of the tool
after it has been dropped or subjected to other
mechanical stresses.
c) Although the tool is designed for the harsh con-
ditions of jobsite use, as with other measuring
instruments it should be treated with care.
d) Although the tool is protected to prevent entry
of dampness, it should be wiped dry each time
before being put away in its transport container.
e) Check to ensure that all symbols are visible when
the tool is switched on.
Check the accuracy of the tool before using it for
f)
detection or measurement.

4.5 Electrical safety

a) Keep the batteries out of reach of children.
b) Do not allow the batteries to overheat and do not
expose them to fire. The batteries may explode or
release toxic substances.
c) Do not charge the batteries.
d) Do not solder the batteries into the tool.
e) Do not discharge the batteries by short-circuiting.
This may cause them to overheat and present a risk
of personal injury (burns).
Do not attempt to open the batteries and do not
f)
subject them to excessive mechanical stress.
