Electromagnetic Compatibility - Hilti DD ST-HCL Manual De Instrucciones

and do not use it in damp or wet conditions. Do
not use the tool where there is a risk of fire or
explosion.
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.
When the tool is brought into a warm environment
j)
from very cold conditions, or vice-versa, allow it
to become acclimatized before use.
k) If mounting on an adapter, check that the tool is
fitted correctly.
l) Keep the laser exit aperture clean to avoid meas-
urement errors.
m) 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.
n) 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.
o) Avoid looking directly into the laser beam.
p) The laser visibility glasses are not laser protec-
tion glasses and do not protect the eyes against
laser beams. As these glasses restrict color vis-
ion, wearing them while driving a vehicle on a
public road is not permissible. They are also no
substitute for sunglasses.
q) Stay alert, watch what you are doing and use com-
mon sense when operating the machine. Don't
use the machine when you are tired or under the
influence of drugs, alcohol or medication. A mo-
ment of inattention while operating machines may
result in serious personal injury.
5.1 Proper organization of the work area
a) Implement suitable safety measures in the area
in which you are working and take care to avoid
directing the beam towards other persons or to-
wards 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) The result obtained may be distorted if the laser beam
passes through a pane of glass or other objects, or if
the wrong adapter is used.
d) Reflection of the laser beam from glass or other
reflective surfaces may cause errors or incorrect res-
ults.
e) Check that the tool is correctly attached to the
guide rail of the drill stand (remove dirt or foreign
matter such as drilling slurry from the guide rail).
f) Use the tool only within its specified limits.
g) If several laser tools are used in the same working
area, care must be taken to avoid confusing the
beams.
h) Do not use the tool in the proximity of medical instru-
ments.

5.2 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.
5.3 Laser classification for Laser Class 2 / Class II
appliances
Depending on the version purchased, the tool complies
with Laser Class 2 in accordance with IEC825-3:2007 /
EN60825-3:2007 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.
5.4 Electrical
a) Do not disassemble the tool in order to attempt
to charge the batteries. The batteries in the tool are
designed to last for the life of the tool. No provision
has been made for battery replacement by the user.
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) Do not allow the batteries to overheat and do not
expose them to fire. The batteries may explode or
release toxic substances.
5.5 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.
