3.2 Intended use
The product described is a rotating laser tool with a visible green rotating laser beam and a reference beam
set at 90° to the main beam. The rotating laser can be used vertically, horizontally and for inclined planes.
The tool is designed to be used to determine, transfer and check levels, verticals, slopes and right angles.
Examples of its uses are: transferring datum lines and height marks, determining right angles for walls,
vertical alignment on reference points and setting out slopes.
▶Use only the HiltiB 12/2.6 and respectively the B 1230 Li ion battery for this product.
▶Use only the Hilti C 4⁄1250 charger for this product.
3.3 Features
The tool allows a single person to level or align in any plane quickly and with great accuracy.
4 speeds of rotation are available for use (0, 90, 300, 600 /min). The preset speed of rotation is 300 /min.
The tool is equipped with the following operating status indicators: auto-leveling LED, inclination angle LED
and shock warning LED.
When automatic leveling is activated for one or both axes, the built-in servo system ensures that the specified
accuracy is maintained. An automatic cut-out is activated when the tool is unable to level itself (i.e. when
the tool is outside its self-leveling range or movement is blocked mechanically) or the tool is knocked off
level (by vibration or an impact). When the tool has switched itself off, rotation stops and all LEDs blink.
Depending on the working distance and ambient light, visibility of the laser beam may be impaired. Visibility
of the laser beam can be improved through use of the target plate. In situations where laser beam visibility
is reduced, e.g. in bright sunlight, use of the laser receiver (accessory) is recommended.
Leveling
After switching on, the tool levels itself automatically within a range of ±5° by way of two built-in servo
motors. LEDs indicate the tool’s current operating status. The tool can be set up directly on the ground or
floor, on a tripod, or with the aid of suitable mounting brackets.
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 (pivot).
In inclined plane mode the inclination can be set manually within a range of ± 5° with the aid of the PRA 2
remote control unit. Alternatively, in inclined plane mode, the slope adapter can be used to achieve slopes
of up to 60%.
Thanks to its built-in shock warning function the tool switches to warning mode if knocked off level, e.g.due
to vibration or impact while in operation (warning mode becomes functional two minutes after completion of
self-leveling). All LEDs blink, the laser beam stops rotating and the laser is switched off.
Combination with other devices
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.
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.

on which it stands should not exceed ± 5°.
2. Press the ON / OFF button. The auto-leveling LED blinks green.
The laser switches on, the beam begins to rotate and the “auto leveling” LED lights as soon as the
tool has leveled itself.
6.3 Working in the vertical plane 7
1. Place or mount the tool so that the control panel faces upwards.
In order to ensure that the tool’s specified accuracy can be maintained, make sure that it is set up
on a level surface or mounted sufficiently level on the tripod or other accessory.
2. Use the visual sighting aids to adjust the tool so that its vertical axis is aligned in the required direction.
The laser switches on, the beam begins to rotate and the “auto leveling” LED lights as soon as the
tool has leveled itself.

*2149767* 2149767 English 9
3. Press the on/off button. After the tool has leveled itself automatically, it projects a stationary laser beam
vertically downwards. This projected point is the reference point and is used to position the tool.
4. Press the rotation speed button in order to see the laser beam in the entire plane of rotation.
5. 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.
6.4 Inclination
For optimum results, check that the PR 3-HVSG A12 is correctly aligned. The best way to do this is by
selecting 2 points, each at a distance of 5 m (16 ft), one to the left and one to the right of the tool, 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.
6.4.1 Setting the slope manually
1. Set up the tool in a suitable position for the application, e.g. on a tripod.
2. Position the rotating laser either at the upper edge or lower edge of the inclined plane.
3. Position yourself behind the tool, facing the control panel.
4. With the aid of the target notch on the head of the tool, bring the tool roughly into alignment with the
inclined plane (parallel to the plane).
5. Switch the tool on and then press the inclined plane mode button. The inclined plane mode LED then
lights. The laser beam switches on as soon as the tool has leveled itself.
6. To incline the plane of rotation, press the + or − button on the remote control unit. Alternatively, the slope
adapter (accessory) can also be used.
When the angle of inclination is set manually, the rotating laser levels the laser plane once and
then fixes it once. Note that this rotating laser does not correct the sloped laser plane for possible
deviation occurring due to a change in ambient conditions and/or shift of the mounting. Vibration,
changes in temperature or other influences that may occur during the course of the day may affect
the position of the laser plane.
7. To return to standard operating mode, the tool must be switched off and then restarted.
6.4.2 Using the slope adapter to set the slope
1. Mount a suitable slope adapter on a tripod.
2. Position the tripod either at the upper edge or lower edge of the inclined plane.
3. Mount the rotating laser on the slope adapter and use the target notch on the head of the PR 3-HVSG A12
to set the tool complete with the slope adapter parallel to the inclined plane.
4. Make sure that the slope adapter is in the zero position (0°).
The control panel of the PR 3-HVSG A12 has to face away from the direction of inclination.
5. Switch the tool on.
6. Press the inclined plane mode button. The inclined plane mode LED then lights on the control panel
of the rotating laser. The tool then begins automatic self-leveling. The laser switches on and begins to
rotate as soon as this is complete.
7. Set the slope adapter to the desired angle of inclination.
When the angle of inclination is set manually, the rotating laser levels the laser plane once and
then fixes it once. Note that this rotating laser does not correct the sloped laser plane for possible
deviation occurring due to a change in ambient conditions and/or shift of the mounting. Vibration,
changes in temperature or other influences that may occur during the course of the day may affect
the position of the laser plane.
6.5 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.
Selecting the speed of rotation
After switching on, the rotating laser always begins to operate at a speed of 300 revolutions per minute. A
slow speed of rotation can make the laser beam appear much brighter. A high speed of rotation makes the

10 English 2149767 *2149767*
laser beam appear more stable. The speed of rotation can be adjusted by pressing the rotation speed button
several times.
Selecting the 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
pressing the line function button several times. The length of the line depends on the distance of the laser tool
from the wall or surface. The laser line can be shifted as desired by pressing the direction buttons (right/left).
6.6 Deactivating the shock warning function
1. Switch the tool on.
2. Press the “Deactivate shock warning” button. The shock warning deactivation LED lights constantly,
indicating that the function has been deactivated.
3. To return to standard operating mode, switch the tool off and then switch it back on again.
6.7 Checking the main and transverse horizontal axes 8
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 visual sighting method (front and rear sights) 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 the two previous steps twice and use the laser receiver to catch the beam and mark points 3 and
4 on the wall.
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 Hilti
Service for calibration.
6.8 Checking the vertical axis 9,10
1. Place the tool in the vertical position on the floor or ground, which should be 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 ground or 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 height of approx. 10 m (33 ft).
6. Pivot the tool through 180° and realign it with the reference point (R) on the ground or floor and with point
(A) at the base of the wall.
7. With the aid of the receiver, mark point (C) at a height of approx. 10 m (33 ft).
If the procedure has been carried out accurately, 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 Hilti Service for calibration.

λειτουργούν με επαναφορτιζόμενες μπαταρίες (χωρίς καλώδιο τροφοδοσίας).
2.1.2 Γενικά μέτρα ασφαλείας
▶Να είσαστε πάντα προσεκτικοί, να προσέχετε τί κάνετε και να εργάζεστε με το ηλεκτρικό εργαλείο
με περίσκεψη. Μην χρησιμοποιείτε ηλεκτρικά εργαλεία, όταν είστε κουρασμένοι ή όταν βρίσκεστε
υπό την επήρεια ναρκωτικών ουσιών, οινοπνεύματος ή φαρμάκων. Μία στιγμή απροσεξίας κατά τη
χρήση του ηλεκτρικού εργαλείου μπορεί να οδηγήσει σε σοβαρούς τραυματισμούς.

σκουπίσετε με στεγνό πανί πριν το τοποθετήσετε στη συσκευασία μεταφοράς του.
▶Ελέγχετε τη συσκευή πριν από σημαντικές μετρήσεις.
▶Κατά τη χρήση, ελέγχετε πολλές φορές την ακρίβεια.
