Before Use - Hilti PD 42 Mode D'emploi

h) Rapid changes in the conditions under which the
measurement is taken, e.g. persons walking through
the laser beam, may lead to inaccurate results.
i) Do not point the tool toward the sun or other
powerful light sources.
5.2 Proper organization of the workplace
a) Avoid unfavorable body positions when working
on ladders or scaffolding. Make sure you work
from a safe stance and stay in balance at all
times.
b) Check the measuring reference setting before
taking the measurement.
c) When the tool is brought into a warm environment
from very cold conditions, or vice-versa, allow it
to become acclimatized before use.
d) As a precaution, check the previous settings and
adjustments you have made.
e) When setting up the tool with the aid of the bubble
level, view the bubble level at a slight angle.
f) 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.
g) Use the tool only within its specified limits.
h) Observe the accident prevention regulations ap-
plicable in your country.
5.3 Electromagnetic compatibility
NOTE
Only for Korea: This device is suitable for the commer-
cial and industrial field and the electromagnetic radiation
encountered in this field (Class A). Users must pay atten-
tion to this point and not use this device in a residential
environment.
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 incor-
rect 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). The tool complies with the

requirements of class A; The possibility of interference
occurring in a domestic environment cannot be excluded.
5.4 General safety rules
a) Check the condition of the tool before use. If the
tool is found to be damaged, have it repaired at a
Hilti service center.
b) The user must check the accuracy of the tool
after it has been dropped or subjected to other
mechanical stresses.
c) Although the tool is designed for the harsh con-
ditions of jobsite use, as with other measuring
instruments it should be treated with care.
d) 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.
5.5 Electrical
a) Keep the batteries out of reach of children.
b) Do not allow the batteries to overheat and do not
expose them to fire. The batteries may explode or
release toxic substances.
c) Do not charge the batteries.
d) Do not solder the batteries into the tool.
e) Do not discharge the batteries by short-circuiting.
This may cause them to overheat and present a risk
of personal injury (burns).
f) Do not attempt to open the batteries and do not
subject them to excessive mechanical stress.
5.6 Laser classification
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.
5.7 Transport
Always remove the batteries before shipping the tool.
CAUTION
Always replace the complete set of batteries.
DANGER
Do not mix old and new batteries. Do not mix batteries
of different makes or types.
