4 Safety instructions

4.1 Basic information concerning safety

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.

4.2 Misuse

The tool and its ancillary equipment may present hazards
when used incorrectly by untrained personnel or when
used not as directed.
a) Never use the tool without having received the ap-
propriate instruction on its use or without having
read these operating instructions.
b) Do not render safety devices ineffective and do
not remove information and warning notices.
c) Have the tool repaired only at a Hilti Service Center.
Failure to follow the correct procedures when
opening the tool may cause emission of laser
radiation in excess of class 3R.
d) Modification of the power tool or tampering with its
parts is not permissible.
e) To avoid the risk of injury, use only genuine Hilti
accessories and additional equipment.
Never point the tool or its accessories toward
f)
yourself or other persons.
g) Use only clean, soft cloths for cleaning. If necessary,
they may be moistened with a little alcohol.
h) Keep laser tools out of reach of children.
i) Measurements to plastic foam surfaces, e.g. poly-
styrene foam, to snow or to highly reflective surfaces,
may result in incorrect readings.
j) Measurements taken to surfaces with low reflectivity
in highly reflective surroundings may be inaccurate.
k) Measurements taken through panes of glass or other
objects may be inaccurate.
l) Rapid changes in the conditions under which the
measurement is taken, e.g. persons walking through
the laser beam, may lead to inaccurate results.
m) Do not point the tool or accessories toward the sun
or other powerful light sources.
n) Do not use the tool as a level.
o) Check the tool before taking important measure-
ments or after it has been dropped or subjected to
mechanical effects such as impact or vibration.
p) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
the risk of electric shock.
q) Check the condition of the extension cord and
replace it if damage is found. Do not touch the AC
adapter if the extension cord or AC adapter are
damaged while working. Disconnect the supply
cord plug from the power outlet. Damaged supply
cords or extension cords present a risk of electric
shock.
r) When switching distance measurement from prism
measurement to reflectorless measurement, make
42
sure that you do not look at the objective lens of the
tool.

4.3 Proper organization of the work area

a) Secure the site in which you are taking measure-
ments and take care to avoid directing the beam
towards other persons or towards yourself when
setting up the appliance. Always wear laser safety
glasses.
b) Use the tool only within the defined application limits,
i.e. do not take readings from mirrors, stainless steel
or polished stone, etc.
c) Observe the accident prevention regulations applic-
able in your country.

4.4 Electromagnetic compatibility

Although the tool complies with the strict requirements
of the applicable directives, Hilti cannot entirely rule out
the possibility of the tool
- causing interference to other devices (e.g. aircraft nav-
igation equipment) or being subject to
- interference caused by powerful electromagnetic radi-
ation, 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.
4.4.1 Laser classification for tools of the Class 3R /
Class IIIa
The tool conforms to laser class 3R based on the
IEC60825-1 / EN60825-1:2007 standard and complies
with CFR 21 § 1040 (Laser Notice 50). This tool may
be used without need for further protective measures.
Do not stare into the beam and do not direct the beam
toward other persons.
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. Always wear laser safety
glasses.
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.
