for which it is not intended presents a risk of fire and
explosion.
g) Observe the special instructions applicable to the
transport, storage and use of Li-ion batteries.
h) When not in use, keep the battery and the charger
away from paper clips, coins, keys, nails, screws
or other small metal objects that could cause a
short circuit at the battery terminals or the charg-
ing contacts. A short circuit at the battery terminals
or charging contacts could result in personal injury
(burns) or fire.
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 or PUA 82 motor
vehicle power adapter to power the tool or charge
the battery. Failure to observe these points may
result in damage to the tool.
k) Use only the battery chargers recommended by
the manufacturer to charge the batteries. Use of a
charger with batteries other than the specific type(s)
for which it is designed presents a risk of fire.
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) Avoid unfavorable body positions when working
from ladders. Make sure you work from a safe
stance and stay in balance at all times.
c) Measurements taken through panes of glass or other
objects may be inaccurate.
d) Ensure that the tool is set up on a steady, level
surface (not subject to vibration).
e) Use the tool only within its specified limits.
f) Check that your PRI 36 is responding only to your
PRA 36 and not to other PRA 36s that may be in use
on the job site.
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 Laser
Class 3R / Class IIIa
a) This tool complies with Laser Class 3R in accordance
with IEC60825-1 / EN60825-1:2007 and Class IIIa in
accordance with CFR 21 § 1040 (FDA). In the event
of direct eye contact with the laser beam, close your
eyes and move your head out of the path of the
beam. Do not look directly into the light source. Do
not direct the laser beam toward persons.
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 be-
yond the controlled area.
h) When not in use, laser tools should be stored in an
area to which unauthorized persons have no access.
i) Switch the laser tool off when it is not in use.
6 Before use
NOTE
The PRI 36 may be powered only by the Hilti PRA 84 G

6.1 Charging the battery
DANGER
Use only the Hilti batteries and Hilti mains adapters
listed under “Accessories”.
6.1.1 Charging a new battery for the first time
Charge the battery fully before using it for the first time.
NOTE
Make sure the system to be charged is standing securely.
6.1.2 Charging a previously used battery
Ensure that the outer surfaces of the battery are clean
and dry before inserting it in the tool.
Li-ion batteries are ready for use at any time, even when
only partly charged. During charging, progress is indi-
cated by the LEDs on the tool.
