5.1 Basic safety information

In addition to the safety precautions listed
in the individual sections of these operating
instructions, the following points must be
strictly observed at all times.

5.2 Misuse

The range meter and its accessories can be
a source of hazard if they are not used
properly or not used for the intended pur-
pose by untrained people.
– Do not use the range meter without suit-
able prior instruction.
– Do not render any safety devices ineffec-
tive and do not remove information and
warning notices.
– Have the range meter repaired only at a
Hilti service center. Unauthorized open-
ing of the range meter may cause the
emission of laser radiation in excess of
class 2.
– Tampering with or modification of the
range meter is not permissible.
– Use only genuine Hilti accessories and
auxiliary tools in order to avoid the risk
of injury.
– Do not use the range meter in atmos-
pheres where there is a risk of explosion.
– Use only a clean, soft cloth for cleaning.
If necessary, moisten the cloth slightly
with pure alcohol.
– Keep the range meter out of the reach of
children.
– Measurements taken to plastic foam
materials, such as polystyrene foam, or
to snow or other strongly reflecting sur-
faces, may be inaccurate.
– Taking measurements to surfaces with
low reflectivity surrounded by areas with
high reflectivity may lead to measure-
ment errors.
– Measurements taken through panes of
glass or other objects may be inaccurate.
– Rapid changes of the measuring condi-
tions, e.g. persons walking through the
laser beam, may lead to measurement
errors.
– Do not direct the range meter towards
the sun or other sources of bright light.
– Do not use the range meter as a levelling
tool.
– Check the range meter before taking
important measurements and after it has
been dropped or subjected to other
mechanical stressing.
– Check the setting of the measuring re-
ference before measuring.

5.3 General safety precautions

Check the range meter for possible damage
before use. If the range meter is found to
be damaged, have it repaired at a Hilti serv-
ice centre. The accuracy of the range meter
must be checked after it has been dropped
or subjected to other mechanical stressing.
– When the range meter is brought into a
warm environment from very cold condi-
tions, or vice versa, allow it to become
acclimatised before use.
– Although the range meter is designed for
the tough conditions of jobsite use, as
with other optical instruments (binocu-
lars, spectacles, cameras, etc.) it should
be treated with care.
– Although the range meter is protected to
prevent entry of dampness, it should be
wiped dry each time before being put
away in its transport container.
– As a precaution, check the settings you
have made before using the range meter.
– When using the circular bubble level
(bull's eye) for alignment, only look at
the range meter from the side.
