2.1 Use of the product as directed
The Hilti PR 3 is a laser tool with a rotating laser beam and a reference beam set at 90° to the main beam.
The tool is designed to be used for determining, checking / transferring levels, verticals, alignment, slopes and right
angles, for example: transferring datum lines and heights, marking out partition walls (vertical and/or at right angles)
or aligning equipment and components in three axes.
Use of tools or AC adapters which show visible signs of damage is not permissible.
Operation outdoors or in damp conditions in “Charging during operation mode” is not permissible.
Hilti supplies various accessories which allow the tool to be used with maximum efficiency.
The tool and its ancillary equipment may present hazards when used incorrectly by untrained personnel or when used
not as directed.
To avoid the risk of injury, use only genuine Hilti accessories and insert tools.
Observe the information printed in the operating instructions concerning operation, care and maintenance.
Take the influences of the surrounding area into account. Do not use the appliance where there is a risk of fire or
explosion.
Modification of the tool is not permissible.
2.2 Features
The tool allows a single person to level or align in any plane quickly and with great accuracy. Automatic leveling (within
±5°): The tool levels itself automatically after switching on. LEDs indicate the tool’s current operating status. The tool
can be set up directly on the floor, on a tripod, or with the aid of suitable mounting brackets.
The preset speed of rotation is 300 /min.

Printed: 08.07.2013 | Doc-Nr: PUB / 5070187 / 000 / 01

The tool is easy to set up and operate and features a rugged casing. The tool is powered by a rechargeable Li‑ion
battery which can be charged while the tool is in operation.
2.3 Horizontal plane
After switching on, the tool levels itself automatically by way of 2 built-in servo motors.
2.4 Vertical plane (automatic leveling)
Vertical alignment is carried out automatically. The +/- buttons on the PRA 2 remote control unit can be used to bring
the vertical plane manually into alignment (rotate).
2.5 Slope
In inclined plane mode, the PRA 2 remote control unit can be used to manually adjust the slope by up to ± 5°.
Alternatively, in inclined plane mode, the slope adapter can be used to achieve slopes of up to 60%.
2.6 Shock warning
The built-in shock warning function (becomes active one minute after completion of auto-leveling): The tool goes into
warning mode if it is knocked off level (due to vibration or impact) while in operation: all LEDs blink; the head of the
laser stops rotating; The laser beam is switched off.
2.7 Automatic cut-out
When automatic leveling is activated for one or both axes, the built-in servo system ensures that the specified accuracy
is maintained.
The tool switches itself off if leveling is unsuccessful (when the tool is set up outside its self-leveling range or movement
is blocked mechanically).
The tool switches itself off when knocked off level (vibration / impact).
When the tool has switched itself off, rotation stops and all LEDs blink.
2.8 Combination with the PRA 2 remote control unit
The PRA 2 remote control unit can be used to control the rotating laser conveniently from a distance. The remote
control function can also be used to adjust alignment of the laser beam.
2.9 Operation in combination with Hilti laser receivers
Hilti laser receivers can be used to detect and indicate the laser beam at great distances. For further information,
please refer to the operating instructions for the laser receiver.
NOTE
Depending on the version purchased, the laser receiver may not be included among the items supplied.
2.10 Speed of rotation
3 speeds of rotation are available for use (300, 600, 1500 /min).
2.11 Increasing the visibility of the laser beam
Depending on the working distance and ambient light, visibility of the laser beam may be impaired.
Visibility of the laser beam can be improved with the aid of the target plate and/or the laser visibility glasses.
When laser beam visibility is reduced due to bright sunshine, for example, we recommend use of the laser receiver
(accessory).

5 Safety instructions
5.1 Basic information concerning safety
In addition to the information relevant to safety given
in each of the sections of these operating instructions,
the following points must be strictly observed at all
times.
5.2 General safety rules
a) Do not render safety devices ineffective and do
not remove information and warning notices.
b) Keep laser tools out of reach of children.
c) Failure to follow the correct procedures when open-
ing the tool may cause emission of laser radiation in
excess of class 2 or, respectively, class 3. Have the
tool repaired only at a Hilti service center.
d) Take the influences of the surrounding area into
account. Do not use the tool where there is a risk
of fire or explosion.
e) (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) 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 or from panes of glass
or through 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) When working in “charging during operation”
mode, attach the mains adapter in a secure posi-
tion,e.g.onatripod.
g) Use the appliance and its accessories etc. in ac-
cordance with these instructions and in the man-
ner intended for the particular type of appliance.
Take the working conditions and the work to be
performed into account. Use of appliances for ap-
plications different from those intended could result
in a hazardous situation.
h) Use of the telescopic staff in the vicinity of over-
head high voltage cables is not permissible.
i) Take care to ensure that no other PR 3 is in use in the
area.The IR control system may influence the tool
you are using. Check the setup from time to time.
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
en
19
Printed: 08.07.2013 | Doc-Nr: PUB / 5070187 / 000 / 01

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 II
appliances
The tool complies with Laser Class 2 in accordance
with IEC825-1:2008 / EN60825-1:2008 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 unintentionally for a brief moment.
This eyelid closure reflex, however, may be negatively
affected by medicines, alcohol 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.
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.
j) Use the mains adapter only for connecting to the
mains supply.
k) Check to ensure that the tool and mains adapter
do not present an obstacle that could lead to a
risk of tripping and personal injury.
l) Ensure that the workplace is well lit.
m) Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
n) Check the condition of the extension cord and
replace it if damage is found. Do not touch the
mains adapter if the extension cord or mains ad-
apter are damaged while working. Disconnect the
supply cord plug from the power outlet. Damaged
supply cords or extension cords present a risk of
electric shock.
o) Do not expose the supply cord to heat, oil or sharp
edges.
p) Never operate the mains adapter when it is dirty
or wet. Dust (especially dust from conductive ma-
terials) or dampness adhering to the surface of
the mains adapter may, under unfavorable condi-
tions, lead to electric shock. Dirty or dusty tools
should thus be checked at a Hilti service center
at regular intervals, especially if used frequently
for working on conductive materials.
q) Avoid touching the contacts.
5.4.1 Battery tool use and care
a) Use only the Hilti battery approved for use with this
tool.
b) Do not expose batteries to high temperatures or
fire. This presents a risk of explosion.
c) The batteries must not be taken apart, crushed,
heated to more than 75°C (167°F) or burnt. Ariskof
fire, explosion or injury through contact with caustic
substances may otherwise result.
d) Avoid ingress of moisture. Moisture may cause a
short circuit resulting in a risk of burning injury or fire.
e) Do not use batteries other than those approved
for use with the applicable tool or appliance. Use
of other batteries or use of the battery for purposes
for which it is not intended presents a risk of fire and
explosion.
f) Observe the special instructions applicable to the
transport, storage and use of Li-ion batteries.
g) Avoid short-circuiting the battery.Before inserting
the battery in the tool, check that the terminals of
the battery and the tool are free from foreign objects.
Short-circuiting the battery terminals presents a risk
of fire, explosion or contact with caustic substances.
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) Use only the specified battery to power the tool
and use only the PRA 85 mains adapter or PRA 86
car charging connector for charging. Failure to
observe these points may result in damage to the
tool.

5. Press the rotation button in order to see the laser
beam in the entire plane of rotation.
6. The vertically rotating beam can be moved to the left
or right by up to 5° by pressing the + and − buttons
on the remote control unit.
7.3 Working with slopes
NOTE
For optimum results, check that the PR 3 is correctly
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.
7.3.1 Setting the slope manually
1. To activate the inclined plane function, press the on
/ off button on the tool for at least 8 seconds when
switching on.
2. After 8 seconds, the inclined plane LED lights con-
stantly indicating that the inclined plane function is
activated.
3. Release the button.
4. The horizontal plane is then no longer monitored.
5. After leveling itself, the laser beam will begin to
rotate.
6. Toinclinetheplaneofrotation,pressthe+or−
button on the remote control unit. Alternatively, the
slope adapter (accessory) can also be used.
7. To return to the standard operating modus, the tool
must be switched off and then restarted.
7.3.2 Setting the slope with the aid of the
PRA 76/78 slope adapter
NOTE
Check that the slope adapter is fitted correctly between
the tripod and the tool (please refer to the operating
instructions).
7.4 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.
7.4.1 Selecting the speed of rotation (revolutions
per minute)
After switching on, the rotating laser always begins to
operate 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 300/min to 600/min to
1500/min by pressing the speed control button several
times.
7.4.2 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
the line depends on the distance between the laser and
thewallortheworkingsurface.Thelaserlinecanbe
shiftedtotheleftortheright,asdesired,bypressingthe
direction buttons (right/left).
7.5 Deactivating the shock warning system
1. Press the on / off button on the tool for at least 4
seconds when switching on.
2. The shock warning LED lights constantly, indicating
that the function has been deactivated.
3. Release the on / off button.
4. To return to the standard operating modus, the tool
must be switched off and then restarted.
7.6 Working with the laser receiver (accessory)
The laser receiver can be used at distances of up to 150
m (492 ft) or when working in unfavorable light. The laser
beam is indicated by visual and audible signals.
NOTE
For further information, please refer to the operating
instructions for the laser receiver.

8 Care and maintenance
8.1 Cleaning and drying
1. Blow dust off the laser exit window.
2. Do not touch the laser exit apertures and filter with
the fingers.
3. Use only a clean, soft cloth for cleaning. If necessary,
moisten the cloth slightly with pure alcohol or a little
water.
NOTE Do not use any other liquids as these may
damage the plastic components.
4. Check the temperature limit values when storing
your equipment, especially in winter and summer,
if you are keeping your equipment stored inside a
vehicle (‑25 °C to +60 °C (77°F to 140°F)).
8.2 Care of the Li-ion battery
Avoid ingress of moisture.
Charge the battery fully before using it for the first time.
In order to achieve maximum battery life, stop discharging
the battery as soon as a significant drop in performance
is noticed.
NOTE
If use of the tool continues, further battery discharge will
be stopped automatically before the battery cells suffer
damage. The tool switches itself off.
Charge the battery with the Hilti charger approved for use
with Li-ion batteries.
NOTE
- A conditioning charge (as is required with NiCd batter-
ies) is not necessary.
- Interruption of the charging procedure has no negative
effect on battery life.
- Charging can be started at any time with no negative
effect on battery life. There is no memory effect (as
with NiCd batteries).
- For best results, batteries should be stored fully
charged in a cool dry place. Storing the battery in
places subject to high ambient temperatures (e.g. at
a window) has an adverse effect on battery life and
increases the rate of self-discharge.
- If the battery no longer reaches full charge, it may
have lost capacity due to aging or overstressing. It
is possible to continue working with a battery in this
condition but it should be replaced in good time.
8.3 Storage
Unpack the tool if it has become wet. Clean and dry the
tool, its transport container and any accessories. Repack
the equipment only once it is completely dry.
Check the accuracy of the equipment before it is used
after a long period of storage or transportation.
8.4 Transport
Use the Hilti toolbox or packaging of equivalent quality
for transporting or shipping your equipment.
CAUTION
Always remove the battery from the tool before ship-
ping.
8.5 Hilti Calibration Service
We recommend that the tool is checked by the Hilti Cal-
ibration Service at regular intervals in order to verify its
reliability in accordance with standards and legal require-
ments.
Use can be made of the Hilti Calibration Service at any
time, but checking at least once a year is recommended.
The Calibration Service provides confirmation that the
tool is in conformance, on the day it is tested, with the
specifications given in the operating instructions.
The tool will be readjusted if deviations from the man-
ufacturer’s specification are found. After checking and
adjustment, a calibration sticker applied to the tool and
a calibration certificate provide written verification that
the tool operates in accordance with the manufacturer’s
specification.
Calibration certificates are always required by companies
certified according to ISO 900x.
Your local Hilti Center or representative will be pleased
to provide further information.
8.5.1 Checking accuracy
In order to ensure compliance with the technical spe-
cifications, the tool should be checked regularly (at least
before each major / relevant job).
8.5.2 Checking the main and transverse horizontal
axes 
1. Set up the tripod approx. 20 m (66 ft) from a wall
and adjust the tripod head horizontally with a spirit
level.
2. Mount the tool on the tripod and use the aiming
notch to aim the tool at the wall.
3. Use the receiver to catch the laser beam and mark
a point (point 1) on the wall.
4. Pivot the tool clockwise through 90° about its own
axis. In doing so, ensure that the height of the tool
does not change.
5. Use the laser receiver to catch the laser beam and
mark a second point (point 2) on the wall.
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.
8.5.3 Checking the vertical axis  
1. Place the tool vertically on a floor base 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) at the
base of the wall (set the rotating laser to medium
speed).
5. With the aid of the receiver, mark point (B) at a
height of approx. 10 m (33 ft).
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 1.5 mm (at 10 m) (0.06" at 33 ft).
If the deviation is greater: Please return the tool to a
Hilti Service Center for calibration.
