General Safety Rules; Before Use - Hilti PP 10 Mode D'emploi

d) Use the tool only within its specified limits.
5.3.1 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).
5.3.2 Laser classification for tools of the classes
3R and IIIa
a) The tool conforms with laser class 3R in accordance
with IEC 825‑1:2003 and class IIIa in accordance
with 21 CFR § 1040(FDA).
b) Tools of the laser class 3R and class IIIa should be
operated by trained personnel only.
c) The area in which the tool is in use must be marked
with laser warning signs.
d) The plane of the laser beam should be well above or
well below eye level.
e) Precautions must be taken to ensure that the laser
beam does not unintentionally strike highly reflective
surfaces.
f) Precautions must be taken to ensure that persons do
not stare directly into the beam.
g) The laser beam must not be allowed to project bey-
ond the controlled area.
h) When not in use, laser tools should be stored in a
place to which unauthorized persons have no access.

NOTE
The tool may be powered only by the PPA 82 battery or
by batteries manufactured in accordance with IEC 285.

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) When the tool is brought into a warm environment
from very cold conditions, or vice-versa, allow it
to become acclimatized before use.
d) If mounting on an adapter, check that the tool is
screwed on securely.
e) Keep the laser exit aperture clean to avoid meas-
urement errors.
f) 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.
g) 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.
h) Check the tool before using it for important meas-
uring work.
i) Check the accuracy of the measurements several
times during use of the tool.
5.4.1 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
as 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.
NOTE
Do not use damaged batteries, do not mix old and new
batteries and do not mix batteries from various manufac-
turers or batteries with different type designations.
6.1 Switching the tool on
Press the ON / OFF button.
NOTE
The PP 10/11 is capable of leveling itself within a range
of +/- 10%. The tool levels itself automatically when set
up within this range. The LED begins to blink when the
inclination of the tool is more than +/- 10% from the
set inclination. The tool should then be rotated in the
direction indicated by the arrow.
The tool can be used.
