5. Safety instructions
In addition to the information relevant to safety given in each
of the sections of these operating instructions, the follow-
ing points must be strictly observed at all times.
5.1 General safety rules
a)
Check the accuracy of the tool before using it to take mea-
surements.
b)
The tool and its ancillary equipment may present hazards
when used incorrectly by untrained personnel or when
used not as directed.
c)
To avoid the risk of injury, use only genuine Hilti acces-
sories and additional equipment.
d)
Modification of the tool is not permissible.
e)
Observe the information printed in the operating instruc-
tions concerning operation, care and maintenance.
f)
Do not render safety devices ineffective and do not remove
information and warning notices.
g)
Keep laser tools out of reach of children.
h)
Check the condition of the tool before use. If the tool is
found to be damaged, have it repaired at a Hilti service
center.
i)
The user must check the accuracy of the tool after it has
been dropped or subjected to other mechanical stresses.
j)
When the tool is brought into a warm environment from
very cold conditions, or vice-versa, allow it to become
acclimatized before use.
k)
Keep the laser exit aperture clean to avoid measurement
errors.
l)
Although the tool is designed for the tough conditions of
underground use, as with other optical and electronic
instruments (e.g. binoculars, spectacles, cameras) it should
be treated with care.
m)
Although the tool is protected to prevent entry of damp-
ness, it should be wiped dry each time before being put
away after use.
n)
Check the accuracy of the measurements several times
during use of the tool.
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 lad-
ders. 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.
f)
If several laser tools are used in the same working area,
care must be taken to avoid confusing the beams.
g) Magnetic fields may affect the accuracy of the tool. It
must thus be kept away from magnetic objects. The tool
is not affected by the Hilti universal adapter.
h)
When working with the receiver, it must be held exactly
at right angles to the laser beam.
i) Do not use the tool in the proximity of medical instru-
ments.
5.3 Laser classification for laser class 3A /
class IIIa appliances
Depending on the version purchased, the tool complies with
Laser Class 3A. This tool may be used without need for fur-
ther protective measures. The eyelid closure reflex protects
the eyes when a person looks into the beam unintentional-
ly for a brief moment. This eyelid closure reflex, however,
may be negatively affected by medicines, alcohol or drugs.
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 Electrical
a) Insulate or remove the batteries before shipping the tool.
b)
To avoid pollution of the environment, the tool must be
disposed of in accordance with the currently applicable
