2.3.2 Laser classification for laser class II
appliances
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. Nevertheless, as with the
sun, one should not look directly into sources of bright
light. In the event of direct eye contact with the laser
beam, close your eyes and move your head out of the
path of the laser beam. Do not direct the laser beam
toward persons.
2.4 Battery tool use and care
a) Check that the tool is switched off before fitting
the battery. Use only the Hilti batteries approved for
use with this tool.
b) Do not expose batteries to high temperatures and
keep them away from fire. This presents a risk of
explosion.
c) Do not disassemble, squash or incinerate batter-
ies and do not subject them to temperatures over
75°C. This presents a risk of fire, explosion or injury
through contact with caustic substances.
d) Avoid ingress of moisture. Moisture in the interior
of the tool may cause a short circuit and chemical
reactions resulting in burns to the skin or fire.
e) Use only batteries of the type approved for use
with the applicable tool. Use of other batteries or
use of the batteries for purposes for which they are
not intended presents a risk of fire and explosion.
f) Observe the special guidelines applicable to the
transport, storage and use of Li-ion batteries.
g) Avoid short circuiting the battery terminals. Check
that the battery terminals and the terminals in the
device are free from foreign objects before inserting
the battery in the device. Short circuiting the bat-
tery terminals presents a risk of fire, explosion and
chemical burns.
h) 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).
i) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for a certain
type of battery may present a risk of fire when used
with other types of battery.
j) When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal to
another. Shorting the battery terminals together may
cause burns or a fire.
k) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact acci-
dentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejec-
ted from the battery may cause irritation or burns.
l) Remove the battery before storing or transporting
the tool.
m) If the battery gets hot while not in use, the battery or
the power tool/battery system may be defective. Put
the power tool/battery system in a suitable place
where it is an adequate distance from flammable

NOTE
For optimum results, check that the PR 3-HVSG is cor-
rectly aligned. The best way to do this is by selecting
2 points on the left and right of the tool, each at 5 m
(16 ft), but parallel to the tool axis. Mark the height of the
horizontal plane and then, after setting the slope, mark
the heights. The tool is aligned optimally only when these
heights are identical at both points.
6.5.1 Setting the slope manually
1. Set up the tool in a suitable position for the applica-
tion, e.g. on a tripod.
2. Position the rotating laser either at the upper edge
or lower edge of the inclined plane.

ation.
NOTE When the angle of inclination is set manually,
the PR 3-HVSG levels the laser plane once and then
subsequently fixes it. Vibration, changes in temper-
ature or other influences that may occur during the
course of the day may affect the position of the laser
plane.
6.6 Working with the PRA 2 remote control unit
The PRA 2 remote control unit makes working with the
rotating laser more convenient and is required in order to
make use of certain functions.
6.6.1 Selecting the speed of rotation (revolutions
per minute)
After switching on, the rotating laser always begins to op-
erate at a speed of 300 revolutions per minute. Working
at a slow speed of rotation can, however, make the laser
beam appear much brighter. A high speed of rotation
makes the laser beam appear more stable. The speed of
rotation can be changed from 0/min to 300/min, 600/min
or 1000/min by pressing the speed control button re-
peatedly.
6.6.2 Line function
The area covered by the laser beam can be reduced to
a line by pressing the line function button on the remote
control unit. The laser beam then appears considerably
brighter. The length of the line can be adjusted by press-
ing the line function button several times. The length of
thelinedependsonthedistanceofthelasertoolfromthe

6. Repeat steps 4 and 5 twice and mark points 3 and
4 on the wall with the aid of the laser receiver.
If the procedure has been carried out accurately, the
vertical distance between the two marked points 1
and 3 (main axis) or, points 2 and 4 (transverse axis),
should each be less than 3 mm (at 20 m) (0.12"
at 66 ft). If the deviation is greater than this, the
tool should be returned to a Hilti Service Center for
calibration.
7.6.2 Checking the vertical axis 9
1. Place the tool in the vertical position on a floor,
which is as flat as possible, approx. 20 m (66 ft)
from a wall.
2. Adjust the position of the tool so that the grips are
parallel to the wall.
3. Switch the tool on and mark the reference point (R)
on the floor.
4. With the aid of the receiver, mark point (A) low on
the wall. Select medium speed.
5. With the aid of the receiver, mark point (B) at a
heightofapprox.10m(33ft).
6. Pivot the tool through 180° and realign it with the
reference point (R) on the floor and with point (A) at
thebaseofthewall.
7. With the aid of the receiver, mark point (C) at a
heightofapprox.10m(33ft).
NOTE If the procedure has been carried out ac-
curately, the horizontal distance between the two
points (B) and (C) marked at a height of ten meters
should be less than 2 mm (at 10 m) (0.08" at 33 ft).
If the deviation is greater: Please return the tool to a
Hilti Service Center for calibration.
