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
purpose by untrained people.
– Do not use the range meter without
suitable prior instruction.
– Do not render any safety devices
ineffective and do not remove
information and warning notices.
– Have the range meter repaired only at a
Hilti service center. Unauthorized
opening of the range meter may cause
the emission of laser radiation in
excess of class 2.
– No changes or manipulations to the
range meter are allowed.
– Use only original Hilti accessories and
auxiliary tools in order avoid the risk of
injury.
– Do not use the range meter in
atmospheres 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
surfaces, may be inaccurate.
– Taking measurements to surfaces with
low reflectivity surrounded by areas with
high reflectivity may lead to
measurement errors.
– Measurements taken through panes of
glass or other objects may be inaccurate.
– Rapid changes of the measuring
conditions, 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.
– If you do not check the range meter
before taking important measurements
and after it has been dropped or
subjected to other mechanical stressing.
– No checking of the setting of the
measuring reference 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
service 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
conditions, or vice versa, allow it to
become acclimatised before use.
– Although the range meter is designed for
the tough conditions of jobsite use, it
should be treated with care, as other
optical instruments (binoculars,
spectacles, cameras, etc.)
– 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.
