Electromagnetic Compatibility; Before Use - Hilti PML 42 Bedienungsanleitung

If several laser tools are used in the same working
f)
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.
en
i) Do not use the tool in the proximity of medical instru-
ments.

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 laser class 2 / class II
appliances
Depending on the version purchased, the tool complies
with Laser Class 2 in accordance with IEC825-1:2007 /
EN60825-1:2007 and Class II in accordance with CFR
21 § 1040 (FDA). This tool may be used without need
for further protective measures. 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. Nevertheless, as with the sun, one
should not look directly into sources of bright light. Do
not direct the laser beam toward persons.

5.6 Liquids
Liquid may leak from the batteries if they are used incor-
rectly. Avoid contact. If contact accidentally occurs,
rinse with water. In the event of the liquid coming
into contact with the eyes, rinse the eyes with plenty
of water and consult a doctor. Liquid leaking from the
battery may cause irritation or burns.
