1. Product information
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).

PR 15 rotating laser – for quick and precise alignment

1. Product information
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.
Functional description, continued

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.
For distances of 1 – 100 m, the manual
detector (optional) is used.

Incline button
For manual setting of the X and Y incline.
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:

2. Safety instructions
2. Safety instructions
The operating instructions and safety precautions
must be read in full and strictly observed. Only then
can the tool be operated safely.
This Laser Product complies with 21 CFR 1040 as applicable
The PR 15 rotating laser corresponds to laser safety
class 2, based on the standards IEC825-1 /
EN60825, and class II based on FDA 21 CFR. The
eyelid closure reflex protects the eyes should anyone
happen to look briefly into the laser beam. However,
this eyelid closure reflex can be impaired by
medicines, alcohol or drugs. These devices may be
used without further protective measures.
Nevertheless, as with the sun, care should be taken
to avoid looking directly into the light source. Do not
direct the laser beam at people.

2. Safety instructions
The tool is designed to be used for determining and
checking horizontal height progressions, inclined
planes, vertical lines, alignment lines, plumbline
points, partition walls (perpendicular and at right
angles to a reference line), such as e.g.:
- transferring metre marks and height marks
- marking out a partition wall (at right angles and
perpendicular)
- aligning equipment and elements in three axes.
Applications for which the tool is designed
Although the Hilti PR 15 fulfils the strict requirements
of the applicable directives, Hilti cannot completely
exclude the following possibilities:
- The PR 15 may cause interference which affects
other equipment (e.g. aircraft navigation systems),
or
- High levels of radiation may cause interference to
the PR 15, possibly leading to incorrect operation.
In these cases, or in other cases of uncertainty,
measurements should be taken to check for correct
operation.
Electromagnetic compatibility (EMC)

61
2. Safety instructions
Continued
- Keep the tool out of reach of children. Laser
instruments do not belong in children’s hands.
- Check the tool for possible damage before use. If
the tool is damaged, have it repaired by a Hilti
service centre.
- If the tool has been dropped or subjected to other
mechanical forces, its accuracy should be
checked. For safety’s sake, check the accuracy
before each use.
- Avoid unusual body positions when carrying out
alignment work from ladders. Make sure that your
stance is secure, and always stay in balance.
- When using adaptors, always ensure that the tool
is screwed on securely.
- When brought from a very low temperature into a
warmer environment, or vice versa, the tool should
be allowed to become acclimatised to the ambient
temperature before it is operated.
- Measurements taken through panes of glass or
other objects may be inaccurate.
- To avoid inaccurate measurements, always keep
the laser beam exit windows clean.
- Although the tool is designed for use on the
construction site, like any other item of optical
equipment (e.g. binoculars, spectacles) it should
be handled with care.
Usage and handling

62
- Although the tool is moisture resistant, it should be
wiped dry before being put away in its carrying
case.
- The tool should be repaired only by Hilti service
centres. Radiation in excess of class 2 may be
emitted if the correct procedures are not observed
when the casing is opened.
- The batteries must be insulated or removed if the
tool is shipped.
- When setting up the tool, make sure that the beam
is not directed at others or at yourself.
- To avoid damage to the environment, the tool and
the batteries must be disposed of in accordance
with the regulations applicable in the country
concerned, or seek advice from the manufacturer.
- The tool is not designed for use in any area which
is at risk of explosions.
- To clean the tool, use only clean, soft cloths. If
necessary, these may be moistened with pure
alcohol (do not use any other liquids, since these
can damage the plastic parts).
