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) The grip is designed to have a certain amount of play
at one side. This is not a fault. It serves to protect
en
the alidade. Tightening the screws on the grip may
cause damage to the thread, making costly repairs
necessary. Do not tighten any screws on the grip!
f) To avoid the risk of injury, use only genuine Hilti
accessories and additional equipment.
g) Do not use the tool in areas where there is a
danger of explosion.
h) Use only clean, soft cloths for cleaning. If necessary,
they may be moistened with a little alcohol.
i) Keep laser tools out of reach of children.
j) Measurements to plastic foam surfaces, e.g. poly-
styrene foam, to snow or to highly reflective surfaces,
may result in incorrect readings.
k) Measurements taken to surfaces with low reflectivity
in highly reflective surroundings may be inaccurate.
l) Measurements taken through panes of glass or other
objects may be inaccurate.
m) Rapid changes in the conditions under which the
measurement is taken, e.g. persons walking through
the laser beam, may lead to inaccurate results.
n) Do not point the tool toward the sun or other powerful
light sources.
o) Do not use the tool as a level.
p) Check the tool before taking important measure-
ments or after it has been dropped or subjected to
mechanical effects such as impact or vibration.

5.3 Proper organization of the work area

a) Secure the area in which you are working and take
care to avoid directing the beam toward other per-
sons or toward yourself when setting up the tool.
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.

5.4 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.
5.4.1 Laser classification for Laser Class 2
products
The laser plummet incorporated in the tools conforms
to Laser Class 2 based on the IEC825-1 / EN60825-
10
01:2008 standard and to CFR 21 § 1040 (Laser Notice
50). The eyelid closure reflex protects the eyes when a
person looks into the beam unintentionally for a brief
moment. This eyelid closure reflex, however, may be
negatively affected by medicines, alcohol or drugs. This
tool may be used without need for further protective
measures. Nevertheless, as with the sun, one should not
look directly into sources of bright light. Do not direct the
laser beam toward persons.
5.4.2 Laser classification for Laser Class 3R
products
The measuring laser incorporated in the tools for distance
measurement conforms to Laser Class 3R based on the
IEC825-1 / EN60825-1:2008 standard and to 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.
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.

5.5 General safety rules

a) Check the tool for damage before use. If the tool
is found to be damaged, have it repaired at a Hilti
service center.
b) Operating and storage temperatures must be ob-
served.
c) Check the accuracy of the tool after it has
been dropped or subjected to other mechanical
stresses.
d) When the tool is brought into a warm environment
from very cold conditions, or vice-versa, allow it
to become acclimatized before use.
e) When a tripod is used, check that the tool is
securely mounted (screwed on) and that the tripod
stands securely on solid ground.
f) Keep the laser exit aperture clean to avoid meas-
urement errors.
g) Although the tool is designed for the tough condi-
tions of jobsite use, as with other optical and elec-
tronic instruments (e.g. binoculars, spectacles,
cameras) it should be treated with care.
h) Although the tool is protected to prevent entry
of dampness, it should be wiped dry each time
before being put away in its transport container.
i) As a precaution, check the previous settings or
any adjustments you may have made.
