Proper Organization Of The Work Area; Before Use; Charging The Battery - Hilti PR 2-HS Manual De Instrucciones

Short-circuiting the battery terminals presents a risk
of fire, explosion or contact with caustic substances.
i) Do not charge or continue to use damaged bat-
teries (e.g. batteries with cracks, broken parts,
bent or pushed-in and/or pulled-out contacts).
j) Use only the PUA 81 AC adapter, PUA 82 motor
en

stance and stay in balance at all times.
c) Readings taken in the vicinity of reflective objects or
surfaces, through panes of glass or similar materials
may produce incorrect results.
d) Ensure that the tool is set up on a steady, level
surface (not subject to vibration).

5.3.1 Electromagnetic compatibility
NOTE
Only for Korea: This device is suitable for the electromag-
netic radiation encountered in residential environments
(Class B). It is intended mainly for use in residential envi-
ronments but may also be used in other environments.
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).
5.3.2 Laser classification for Laser Class 2/Class II
Depending on the version purchased, the tool com-
plies 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 un-
intentionally for a brief moment. This eyelid closure reflex,
however, may be negatively affected by medicines, alco-
hol 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.
