Safety Instructions - Hilti PP 10 Operating Instructions Manual

5 Safety instructions

5.1 Basic information concerning safety
The tool is designed to be used for determining, transfer-
ring or checking alignment in the horizontal and inclined
planes.
In addition to the information relevant to safety given in
each of the sections of these operating instructions, the
en
following points must be strictly observed at all times.
5.2 Misuse
a) The tool and its ancillary equipment may present
hazards when used incorrectly by untrained per-
sonnel or when used not as directed.
b) To avoid the risk of injury, use only genuine Hilti
accessories and additional equipment.
c) Modification of the tool is not permissible.
d) Observe the information printed in the operat-
ing instructions concerning operation, care and
maintenance.
e) Do not render safety devices ineffective and do
not remove information and warning notices.
Keep laser tools out of reach of children.
f)
g) Failure to follow the correct procedures when open-
ing the tool may cause emission of laser radiation in
excess of class 3. Have the tool repaired only at a
Hilti service center.
h) Take the influences of the surrounding area into
account. Do not use the tool where there is a risk
of fire or explosion.
i) (Statement in accordance with FCC §15.21):
Changes or modifications not expressly approved
by the manufacturer can void the user's authority to
operate the equipment.
5.3 Proper organization of the work area
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) Measurements taken through panes of glass or other
objects may be inaccurate.
c) Ensure that the tool is set up on a steady, level
surface (not subject to vibration).
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 complies with Laser Class 3R in accordance
with IEC825-1:2003 / EN60825-1:2003 and Class IIIa
in accordance with CFR 21 § 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 height.
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 an
area to which unauthorized persons have no access.
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.
