Description of functions, continued
The point from which the measurement is taken is clearly identified
by the red spot. The range of the tool depends on the reflectance
and finish of the target surface.
When reflectance of the target is good:
- Target the object directly
When reflectance of the target is unsuitable:
Use the P A411 target plate.
- White side, when reflectance is
excessive.
- Brown side, when reflectance is too low.
- Compact and functional design
- Simple, self-explanatory menu selection and menu settings
- One-man, hand-held operation for speed of use
- Large display (can be illuminated)
- The last nine measurements can be memorised.
- Addressable, intermediate memory (10 values)
- Memory capacity for 1000 values, with group codes and identification tags
- Numeric keypad
- Built-in calculation functions
- Function menus with various special measuring functions
(triangle calculations, mean values, tracking, etc.)

2. Safety information
2. Safety information
Please read this now!
This information is intended to enable owners and users of the Hilti
PD 25 to identify any operating risks in good time, i.e. to eliminate
any such risks in advance where possible.
The owner of the tool must ensure that these instructions are understood and followed by all users.
Purpose
The Hilti PD 25 is intended for the following range of applications:
• Measuring distances
• Calculation of areas, volumes, hypotenuse and angles
• Addition and subtraction of lengths
• Multiplication, division, squares and square roots of measured
values
• Setting out distances
• Saving measurement data
• Special measuring functions
Intended uses
• Use of the product without prior instruction
• Use of the product outside its operating limits
• Rendering safety devices ineffective or removing notices and
warning signs
• Opening the product unless expressly permitted in certain cases
(e.g. to replace the batteries)
• Making conversions or modifications to the product, unless
expressly approved by Hilti
• Deliberately dangerous or careless behaviour on scaffolding,
when climbing ladders or when taking measurements in the vicinity of operating machinery or the exposed parts of machines or
other equipment
• Aiming directly at the sun or other powerful source of light
• Deliberately dazzling other persons
• Use of remote mode with a personal computer that is not earthed
/ grounded (e.g. battery-powered laptop that is not earthed /
grounded)
Examples of misuse
WARNING
Misuse may lead to injury , malfunction and damage to property.
The owner must inform the user of the operating risks associated
with the equipment and the corresponding safety precautions.
The PD 25 laser range meter may be operated only when the user
has received prior instruction.
14
Operating risks
WARNING
Use of the product without instruction or with incomplete instruction
may lead to errors by the operator or misuse and thus to accidents
resulting in serious personal injury , pecuniary damage or damage to
property and the environment.
Preventative measures
All users must observe the safety information issued by the manufacturer and the owner’s instructions.

Operating limits
WARNING
The owner is responsible for the correct use of the equipment, the
use of the equipment by his employees, their instruction and the
operating safety of the equipment.
The owner has the following obligations:
• To ensure that he has understood the safety information on the
product and the information contained in the operating instructions.
• To be aware of the locally applicable industrial accident prevention regulations.
• To notify Hilti immediately of any safety-related defects or deficiencies in the equipment.
The product is suitable for use in atmospheres permanently habitable by humans. It must not be used in corrosive or explosive environments. Exposure to rain for short periods during use is permissible.
See “Technical data” section.
Environment
Responsibility of the manufacturer of the original equipment,
Hilti Corporation, FL-9494 Schaan (subsequently referred to as
“Hilti”)
Hilti is responsible for supplying a technically safe product in faultless
condition, including operating instructions and original accessories.

2. Safety information
Intended uses, continued
Operating limits, continued
WARNING
Care must be taken to avoid incorrect measurements.
Preventative measures
Keep the receiving lens clean. It should be cleaned at regular intervals.
See: “Cleaning and drying”.
WARNING
Take care to avoid incorrect measurements caused by using a
defective product or a product which has been dropped or subjected
to any other inadmissible stresses or changes.
Preventative measures
Take measurements periodically to check the accuracy of the product, particularly after it has been exposed to excessive stresses
and before and after important measuring tasks.
WARNING
Failure to adequately cordon off the area in which you are measuring may lead to dangerous situations in road traffic, on building
sites or in industrial plants, etc.
Preventative measures
Always ensure that the area in which you are carrying out measuring work is properly cordoned off. Observe the statutory accident
prevention regulations and road traffic regulations of the applicable
country.
WARNING
Taking measurements from surfaces with low reflectance surrounded by areas with high reflectance may lead to measurement errors.
Preventative measures
Take measurements from the brown side of the Hilti P A411 target
plate when the PD 25 is used at the limit of its range.

2. Safety information
Operating limits, continued
Note
Opening the product without authorisation will not only invalidate the
warranty , it may also cause malfunctions and measuring errors.
Preventative measures
Do not open the product. Only the battery compartment cover
should be opened (slid to the side) when replacing the batteries.
Note
If the equipment is not used for lengthy periods, there is a risk of it
being damaged by leaking batteries.
Preventative measures
Remove the batteries if you do not intend to use the equipment for
some time.
Warning
At regular intervals or before measuring, check that the folding pointer functions correctly .
The symbol illustrated is shown in the display .
Warning
Using the P A421 telescopic sight to view the directly reflected beam
from the PD 25 is hazardous to the eyes when the tool is aimed at
surfaces with mirror-like reflectance or which cause unexpected
reflections (e.g. mirror, metal surfaces, window panes, prisms).
Preventative measures
Do not aim the telescopic sight at surfaces with mirror-like reflectance or which cause unexpected reflections.
Warning
The laser beam can be set to “laser beam permanently on”, thus
possibly dazzling other persons when the tool is switched on unintentionally or handled without due care.
Preventative measures
When the tool is used in this operating mode, ensure that other persons cannot be dazzled.

2. Safety information
Operating limits, continued
Note
The tool has an accuracy of ± 3 mm at room temperature. In order
to achieve this accuracy , also with calculations, measurements
should be taken carefully .
Note
Different measuring reference points can be selected. To achieve
accurate results, ensure that the correct measuring reference point
on the tool has been selected.
Warning
When taking measurements from a tripod in directly opposite directions (pivoting the tool through 180°), failure to select the correct
measuring reference point may be a cause of error.
Preventative measures
Set the measuring reference point to the tripod axis.
Check the symbol shown in the display:

2. Safety information
Disposal
WARNING
Improper disposal of the equipment may lead to the following:
• Burning of plastic components generates toxic fumes which may
present a health hazard.
• If damaged or exposed to very high temperatures, batteries may
explode, causing poisoning, burns, acid burns or environmental
pollution.
• Careless disposal enables unauthorised persons to make improper use of the equipment, which may lead to serious injury to
themselves or a third party and to pollution of the environment.
Preventative measures
Most of the materials from which Hilti tools are manufactured can be
recycled.
The materials must be correctly separated before they can be recycled.
In many countries, Hilti has already made arrangements for taking
back old tools for recycling.
Ask your Hilti customer service department or Hilti representative
for further information. Please help to protect our environment.
