1. Product Information
The Hilti PR 60 is a rotating laser level with a rotating, invisible
laser beam.
Features
- Using the PR 60 rotating laser, a single person can level any
plane quickly and with great accuracy - always in conjunction
with the PA 350 detector.
- The speed of rotation of the PR 60 is 600 rpm (revolutions per
minute) when the tool is levelled.
- Automatic levelling (within ±5°):
Levelling takes place automatically after the tool is switched
on by way of two built-in servo motors for the x and y axes.
The beam switches on once the specified accuracy and full
speed of rotation has been reached.
- The built-in liquid compensation system ensures high
accuracy and optimum beam stabilisation over the entire
service life of the unit.
- LEDs indicate the current operating status.
- Built-in shock warning function: The tool switches to warning
mode should it be knocked off level during operation (vibration
/ impact); the auto-levelling and shock warning LEDs blink and
the speed of rotation of the head is reduced to 150 rpm.
- Automatic cut-out: The laser beam does not switch on and the
auto-levelling LED blinks when the tool is set up outside its
self-levelling range or when rotation is blocked mechanically.
- The tool can be mounted on a tripod with 5/8” thread or
placed directly on a steady supporting surface.
- Easy to operate, robust construction, reasonable weight.

Shock warning LED
During operation, the tool monitors its own steady position. The
laser switches off and the tool indicates a warning should it
suddenly be brought out of level due to vibration or an impact:
The auto-levelling LED and shock warning LED blink rapidly.
The shock warning LED lights continuously (red) when the shock
warning function has been deactivated.
Shock warning button
- The shock warning function is activated each time after the
tool is switched on and levelling has been achieved.
- To deactivate the shock warning function, press the button
twice in quick succession. The shock warning LED then lights
continuously (Red).
- The shock warning function can be reactivated by pressing the
button once or switching the tool on again. The LED then no
longer lights.
CAUTION
It is possible that no shock warning is given if the height of the
tripod drops very slowly and parallel to the level at which it was
set. The level should thus be checked at regular intervals.

PR 60 quick-start instructions
1. Set up the tripod (e.g. PA 910) on a steady, approximately
horizontal surface. Take care to ensure that as many
measuring points as possible can be reached.
2. Mount the PR 60 correctly on the tripod.
3. Switch on the tool.
The auto-levelling LED blinks, the shock warning function is
activated and the remaining battery capacity indicated.
Levelling takes place automatically (under the most
unfavourable conditions, within 90 sec.), the auto-levelling
LED extinguishes and the head begins to rotate at the
operating speed of 600 rpm.
The laser beam does not switch on and the auto-levelling LED
blinks when the tool is set up outside its self-levelling range
(±5°) or when rotation is blocked mechanically.
To remedy this, proceed as follows:
- Switch off the PR 60
- Level the tripod approximately by hand
- Switch on the PR 60 again
4. Attach the PA 350 detector correctly to the surveyor’s rod.
Switch on the detector and begin work.
When working in an unsteady environment (vibration,
wind,...), it may be of advantage to switch off the PR 60’s
shock warning function. In this case, however, unintentional
displacement of the tool will be ignored. The tool then relevels
itself automatically. The level should thus be checked at
regular intervals.

The Hilti PA 350 detector is designed to detect the laser beam
emitted by rotating lasers.
Features
- When a laser beam strikes the detection window, a liquid
crystal display indicates whether the detector lies below,
above or exactly in the reference plane (at the height of the
mark).
- The visual indicators (arrows) and acoustic signal help the
user to find the reference plane.
- The detector can be used on its own or it may be mounted on
the telescopic rod or attached to a wooden batten or frame
etc. using a suitable holder.
- To assist in finding the laser plane, one of two laser plane
indicator area widths (narrow or standard) may be selected. A
bar is shown in the display when the laser plane is within
these areas. (Please refer to the section on “Compensation”.)
- Automatic cut-out
Battery power is switched off automatically when no laser
beam is detected over a period of more than approx. 30
minutes.
- Indicates the status of the PR60: The PA 350 detects the
warnings transmitted by the PR 60 and indicates «shock

seconds, as follows:
3. Operation and use
Setting up and operating the tool, continued
Compensation
To make it easier to find the laser plane, one of two laser plane
indicator area-width ranges (narrow or standard) may be
selected. A centre bar is shown in the display when the laser
plane is within these ranges.
For very high accuracy
To further increase the accuracy of the detector, compensation
readings may be taken to eliminate the tolerance range of the
selected laser indicator area width. To do this, the detector is
moved through the plane of the laser beam and the point
marked at which the centre bar is indicated. The detector is then
moved further in the same direction until the centre bar again
disappears. A second mark should be made at this position. The
laser plane then lies exactly at the mid point between these two
marks (zero tolerance).

8. The mark(s) can be made once the desired position has been
determined.
9. Switch off the PR 60 and the PA 350 detector (using the ON /
OFF button) after finishing work.
When working in an unsteady environment (vibration, wind,...), it
may be of advantage to switch off the PR 60’s shock warning

tool will be ignored. The tool then relevels itself automatically.
The level should thus be checked at regular intervals.

Check horizontal alignment of the PR 60 in the X-axis as follows:
1. Set up the tripod approx. 20 m from a wall (the top plate of the
tripod must be horizontal).
2. Mount the tool on the tripod.
The tool must lie flat on the tripod top plate.
With the PA 910, ensure that all three feet of the tool are in
contact with the plate.
3. Switch on the PR 60 and wait until it has levelled itself.
4. Use the detector to mark a reference line on the wall (mark A).
5. Switch off the PR 60.

6. Release the tripod screw slightly and pivot the tool carefully
through 180°. The tripod must not be moved as this is done.
Secure the tool again.
7. Switch on the PR 60.
8. Use the detector to mark the height of a reference line on
the wall (mark A1).
When this procedure is carried out carefully, the distance
between the marks A and A1 should be less than 3 mm.
The tool should be readjusted if the distance between the marks
is greater than 3 mm.
The indicator area width of the PA 350 detector must be set to
“narrow”. To carry out this check with greatest possible accuracy,
please follow the instructions on finding the laser plane in the
“Compensation” section.
9. Horizontal alignment of the PR 60 in the Y-axis should be
checked in the same way.

Adjusting the tool
WARNING
- The PR 60 rotating laser may be adjusted only by trained,
experienced persons. If you are unsure of the procedure,
please contact your Hilti service centre.
- Accuracy cannot be guaranteed if adjustment is not carried
out exactly in accordance with instructions.
- The tool must be adjusted in the X and Y axes. For each axis,
the tool must be adjusted in two 180° opposite directions.
Checking and adjusting horizontal alignment must be
carried out for both the X and Y axes in immediate
succession.
(After proceeding as described at “Checking horizontal rotation
in the X-axis”, steps 1 - 8)
1. Press and hold the button and then also press the
button. Release both buttons.
Press the button again within 3 seconds. The shock
warning and battery condition indicators light alternately in a
counter-clockwise direction.
2. Use the supplied adjusting wrench to turn the adjusting screw
until the laser beam is positioned exactly between marks A
and A1. Use the detector to check this.

7. Adjust horizontal alignment of the Y-axis in the PR 60 in the
same way (following steps 1 - 8 as described at “Checking
horizontal rotation in the Y-axis”.
3. Pivot the tool through 180° (not the tripod).
4. Use the detector to check that the laser beam lies exactly
between the marks A and A1.
5. If this is the case, adjustment of the X-axis is complete.
6. If this is not the case, repeat steps 1- 4.
The tripod must not be moved or knocked off level during the
entire adjustment process. Nevertheless, if this happens, press
the button again and the tool will level itself automatically.
Repeat steps 1 - 8 as described at «Checking horizontal
rotation».
One revolution of the adjusting wrench corresponds to approx. 6
mm @ 20 m.

Checking oblique error
The procedure for checking oblique error is intended to be
applied once only when a new tool is received or to check a tool
previously used by other persons. Oblique error cannot change
during the service life of the tool.
Before carrying out this check
- Horizontal rotation must have already been checked.
Any deviations must be within the tolerance range or have
been corrected.
- The top plate of the tripod must be horizontal and the tool
must lie flat on the plate.
Procedure
1. Set up the tripod with the tool at the mid point between walls A
and B.
2. Switch on the PR 60 and wait until it has levelled itself.
3. Use the PA 350 detector to mark the height of the reference
lines on walls A and B (marks a and b).
44
5. Set up the tripod with the tool 1-2 metres from wall A.
6. Switch on the PR 60 and wait until it has levelled itself.
7. Use the detector again to mark the height of the reference
lines on walls A and B (marks a’ and b’).
8. Measure the distance between each of the marks on both
walls. The difference between Db and Da must be < 3 mm.
Please contact your Hilti representative if the deviation is
> 3 mm.
