Hilti PM 2-L Operating Instructions Manual page 20

m) When the tool is brought into a warm environment
from very cold conditions, or vice-versa, allow it
to become acclimatized before use.
n) Make sure that the tool is mounted securely when
adapters or accessories are used.
o) Keep the laser exit aperture clean to avoid meas-
urement errors.
p) 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.
q) 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.
r) 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
tools
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.
Do not solder the batteries into the tool.
f)
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
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.
