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 Basic information concerning safety

a) Operate the tool only as intended and when it is
in faultless condition.
b) Do not render safety devices ineffective and do
not remove information and warning notices.
c) Operate the tool within the specified temperature
range.
d) The laser visibility glasses have no protective
function and do not protect your eyes from laser
light. As the laser visibility glasses restrict color
vision, they should be worn only when working
with this tool and must not be worn while driving
a vehicle on a public road.
e) Keep laser tools out of reach of children.
f) Failure to follow the correct procedures when open-
ing the tool may cause emission of laser radiation
in excess of Class 3R (IIIa). Have the tool repaired
only at a Hilti service center.
g) Take the influences of the surrounding area into
account. Do not use the tool where there is a risk
of fire or explosion.

5.2 Proper organization of the work area

a) Secure the area in which you are working and
take care to avoid directing the beam towards
other persons or towards yourself when setting
up the tool.
b) Avoid unfavorable body positions when working
from ladders. Make sure you work from a safe
stance and stay in balance at all times.
c) Measurements taken through panes of glass or other
objects may be inaccurate.

d) Ensure that the tool is set up on a steady, level
surface (not subject to vibration).
e) Use the tool only within its specified limits.
5.3 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 incorrect 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).
5.4 Laser classification for tools of the class 3R
(IIIa)
a) Tools of the laser class 3R and class IIIa should be
operated by trained personnel only.
b) The area in which the tool is in use must be marked
with laser warning signs.
c) The plane of the laser beam should be well above or
well below eye height.
d) Precautions must be taken to ensure that the laser
beam does not unintentionally strike highly reflective
surfaces.
e) Precautions must be taken to ensure that persons do
not stare directly into the beam.
f) The laser beam must not be allowed to project bey-
ond the controlled area.
g) When not in use, laser tools should be stored in an
area to which unauthorized persons have no access.
