Electromagnetic Compatibility - Hilti PM 4-M Manual De Instrucciones

This will ensure that the safety of the power tool is
maintained.
m) The user must check the accuracy of the tool
after it has been dropped or subjected to other
mechanical stresses.
n) When the tool is brought into a warm environment
from very cold conditions, or vice-versa, allow it
to become acclimatized before use.
o) Make sure that the tool is mounted securely when
adapters or accessories are used.
p) Keep the laser exit aperture clean to avoid meas-
urement errors.
q) 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.
r) 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.
s) Check the accuracy of the measurements several
times during use of the tool.
5.2 Proper organization of the workplace
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 ladders. 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 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
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
Under abusive conditions, liquid may leak from the bat-
tery. Avoid contact. If contact accidentally occurs,
flush 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 ejected from the
battery may cause irritation or burns.
