Hilti PML 42, Operating Instruction

Page: 10 / 93

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 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.
5.5 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 cur-
rently applicable national regulations. Consult the
manufacturer if you are unsure of how to proceed.
c) Keep the batteries out of reach of children.
d) Do not allow the batteries to overheat and do not
expose them to fire. The batteries may explode or
release toxic substances.
e) Do not charge the batteries.
f) Do not solder the batteries into the tool.
g) Do not discharge the batteries by short circuiting
as this may cause them to overheat and present
a risk of personal injury (burns).
h) Do not attempt to open the batteries and do not
subject them to excessive mechanical stress.
i) Do not use damaged batteries.
j) Do not mix old and new batteries. Do not mix
batteries of different makes or types.
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.
