• Have the range meter repaired only at a Hilti service cen-
tre. 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 from plastic foam materials, such as
polystyrene foam, or from snow or other strongly reflect-
ing surfaces, may be inaccurate.
• Taking measurements to surfaces with low reflectivity sur-
rounded by areas with high reflectivity may lead to mea-
surement 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 impor-
tant measurements and after it has been dropped or sub-
jected to other mechanical stressing, measurements may
be inaccurate.

4.3 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 condi-
tions 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.
4.4 Proper organization of workplace
• Secure the area in which you are measuring. When setting
up the range meter, take care to avoid directing the beam
towards yourself or other people.
• Avoid unfavourable body positions when working on lad-
ders or scaffolding. Make sure you have a stable stance
and avoid danger of overbalancing at all times.
• Use the range meter only while observing the specified
operating conditions, i.e. not directed towards a mirror,
bright chromium steel, polished stone, etc.
• Observe accident prevention regulations in force in the
country you are working.
