General warning
Read the operating instructions before use.
These numbers refer to the corresponding illustrations. The
illustrations can be found on the fold-out cover pages. Keep these
pages open while studying the operating instructions. In these
operating instructions, the PML 32 line laser is referred to as «the

The type designation and serial number can be found on the type plate
on the tool. Make a note of this information in your operating
instructions and always refer to it when making an enquiry to your
Hilti representative or service department.
Type : PML 32
Serial no.: ___________
Warning signs

The tool projects two laser lines at 90° to each other
(when projected onto a vertical, even surface situated at
90° to the tool). Leveling is automatic within ±5°.
The automatic leveling system can be deactivated for
applications in an inclined plane.
Operating modes:
- Horizontal laser beam

5. Safety precautions
5. Safety precautions
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 Correct use
The tool is designed for indoor use.
Vertical and/or horizontal lines can be projected by the
tool. The tool levels itself automatically.
The automatic self-leveling system must be deactivated
when the tool is used for applications in an inclined
plane.
–Check the accuracy of the tool at regular intervals.
–To achieve maximum accuracy, project the lines onto
an even, vertical surface. Align the tool at 90° to the
surface.
–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 original Hilti
accessories and additional equipment.
–Modification of the tool is not permissible.
–Observe the information printed in the operating
instructions concerning operation, care and
maintenance.

10
5. Safety precautions
–Do not render safety devices ineffective and do not
remove information and warning notices.
–Keep laser tools out of reach of children.
–Have the tool repaired only at a Hilti service centre.
Failure to follow the correct procedures when opening
the tool may cause emission of laser radiation in
excess of class 2.
–Do not expose the tool to rain or snow and do not use
it in damp or wet environments or where there may be
a risk of explosion.
5.3 Proper organization of the workplace
–Secure the area in which you are measuring and take
care to avoid directing the beam towards other
persons or towards yourself while setting up the tool.
–Avoid unfavorable body positions when working on
ladders or scaffolding. Make sure you work from a
safe stance and stay in balance at all times.
–Measurements taken through panes of glass or other
objects may be inaccurate.
–Ensure that the tool is set up on a steady surface (not
subject to vibration).
–Use the tool only within its specified limits.

5. Safety precautions
5.3.1 Electromagnetic compatibility
Although the tool complies with the strict requirements
of the relevant directives, Hilti cannot entirely rule out
the following possibilities:
–The tool may cause interference to other equipment
(e.g. aircraft navigation equipment).
–The tool may be subject to interference caused by
powerful radiation, which may lead 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.
5.3.2 Laser classification
The tool conforms to laser class 2 based on the
IEC825-1 / EN60825-01 standard and class II based on
CFR 21 § 1040 (FDA). The eyelid closure reflex protects
the eyes when a person looks into the beam
unintentionally for a brief moment. Nevertheless, the
eyelid closure reflex may be negatively affected by
medicines, alcohol or drugs. This tool may be used
without need for further protective measures.
Nevertheless, as with the sun, one should not look
directly into sources of bright light. Do not direct the
laser beam toward persons.
Laser information plates based on IEC825 / EN6082-01:

12
Laser information plates for the USA based on CFR 21
§ 1040 (FDA):
This laser product complies with 21 CFR 1040, as
applicable.
5.4 General safety precautions
–Check the tool for possible damage before use.
If it is found to be damaged, have it repaired at a Hilti
service centre.
–The accuracy of the tool must be checked after it has
been dropped or subjected to other mechanical
stresses.
–When the tool is brought into a warm environment
from very cold conditions, or vice-versa, allow it to
become acclimatized before use.
–If mounting on an adaptor, ensure that the tool is
screwed on securely.
–Keep the laser exit aperture clean to avoid
measurement errors.
–Although the tool is designed for the tough conditions
of jobsite use, as with other optical instruments
(binoculars, spectacles, cameras) it should be treated
with care.
5. Safety precautions

13
–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.
5.4.1 Electrical hazards
–The batteries must be insulated or removed from the
tool before it is shipped.
–The tool and the batteries must be disposed of in
accordance with national regulations in order to avoid
environmental pollution. Consult the manufacturer if
you are unsure.

6. Operation
6.1 Inserting new batteries
-NOTE-
Do not use damaged batteries.
Do not mix old and new batteries. Do not mix batteries of different
makes or types.
1. Bring the two parts of the tool into the closed
position.
2. Press the battery compartment release button.
3. Pull the battery holder downwards out of the tool.
4. Replace the batteries.
-CAUTION-
Take care to observe correct polarity when inserting
the batteries.
5. Close the battery compartment. Check that it
engages securely.

7. Operation
7. Operation
-NOTE-
The pendulum is locked when the tool is in the closed position (laser
beam blinks).
7.1 Operation
7.1.1 Bringing the tool into the operating position
1. Open the tool to the 90° or 180° position.
2. Bring the reference line into alignment with (parallel
to) the top edge of the base section.
-NOTE-
The pendulum is able to swing freely when the
reference line is parallel to the base section, when
the pendulum lockbutton is not pressed in and
when the tool is set up in a horizontal position
(≤±5°).
The laser beam blinks rapidly when the tool is
unable to level itself automatically.
7.1.2 Switching on the laser beam
To switch on only the horizontal beam:
1. Press the selector button once.

16
7. Operation
To switch on only the vertical beam:
1. Press the selector button twice.
To switch on the horizontal and vertical beams:
1. Press the selector button three times.
7.1.3 Working in an inclined plane
1. Press the pendulum lockbutton (the pendulum is
then locked).
2. Switch on the horizontal and/or vertical beam.
-NOTE-
The laser beam blinks approx. every 2 seconds
when the pendulum is locked.
7.1.4 Switching the tool off
1. Press the selector button repeatedly (1-3 times
depending on previous operating mode) until the
laser beam is no longer visible and the LED no
longer lights.
-NOTE-
The tool switches itself off automatically after
approx. 15 minutes.
