PR 15 rotating laser – for quick and precise alignment
The Hilti PR 15 is a rotating laser level with a rotating
laser beam and a plumbline beam offset by 90°.
Features
- Rotational speeds of 0, 80 or 300 r.p.m.
(revolutions per minute) are possible.
- When rotation is switched off, the laser beam can
also be aligned manually.
- LEDs indicate the current operating status.
- Can be set up directly on the ground, on a tripod,
on a wall mounting or sight rail (batter board)
mounting (vertical mode).

Levelled plane (automatic alignment)
Alignment takes place automatically after switching
on the tool, via 2 built-in servo motors for the X and Y
directions. The beam only switches on when the
specified accuracy has been reached.
Plane inclined in the X direction (defined incline
direction)
Inclination in the X direction can be set using the
servo button. The Y direction is held horizontal by the
servo system.
Plane at any desired inclination (free alignment)
The inclination can be matched, through (alternate)
operation of the X and Y motors in accordance with
given markers or contours.
Vertical plane (automatic alignment)
Alignment according to the plumbline (X direction)
takes place automatically. With the servo button, the
vertical plane can be manually aligned (rotated).
Inclined plane vertical (manual alignment)
In the inclined plane mode, the tool can be manually
aligned using the servo buttons that control the servo
motors.

Automatic cut-out
In the case of automatic levelling of one or both
directions, the servo system monitors adherence to
the specified accuracy. Cut-out takes place:
- if levelling is not achieved (levelling range
exceeded or mechanical blockage)
- if the tool is put out of plumb (shock/jolt).
After switch-off has taken place, the rotation switches
off, the laser beam flashes, the Operation LED
flashes red, alternating with the Incline LED.
Increased visibility of the laser beam
Laser beam visibility varies depending on the
working distance and ambient brightness. With the
aid of a special reflective plate (beam catcher), the
beam can be “caught” and held at a specific point.
The laser beam oscillates automatically at the
desired point within a range of approx. ± 200 to 500
mm. This arc therefore appears considerably
brighter.
The beam catcher is used at distances
of 1 – 30 m.
1. Product information
For distances of 1 – 100 m, the manual
detector (optional) is used.

For manual setting of the X and Y incline.
1. Product information
Press the Incline button a first time:
Align X incline using servo button .
X LED lights up red. Y LED lights up green.
Y direction is levelled automatically.
Press the Incline button a second time:
Align Y incline using servo button .
X LED off. Y LED lights up red.
X direction remains inclined as before.
If the previous job was carried out using the
manual incline setting, then the Incline button
must be pressed within 3 seconds after switching
on. In this way, one can continue to work using the
previous incline setting.
If no button is pressed within 3 seconds after
switching on the tool, automatic levelling (X and
Y) or a reset takes place.
The X and Y LEDs light up green:
