1. Product information

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 PA 411 target plate.

-White side, when reflectance is excessive.

-Brown side, when reflectance is too low.

Features of the PD 25

-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.)

-RS 232 interface for transferring data to a PC, etc.

-Built-in theft deterrent

-Switches off automatically

-Built-in bubble level

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

Intended uses

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

Examples of misuse

•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)

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.

13

2. Safety information

Intended uses, continued

Operating limits

See “Technical data” section.

Environment

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.

Examples of misuse

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.

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.

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.

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 PA 411 target plate when the PD 25 is used at the limit of its range.

Continued

15

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 PA 421 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.

16

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:

17

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.
