Safety instructions
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.
General safety rules
-
Keep other persons, especially children, away from the area in which the work is being carried out.
-
Check the condition of the tool before use. If the tool is damaged, have it repaired at a Hilti Service Center.
-
Do not render safety devices ineffective and do not remove information and warning notices.
The tool must be checked at a Hilti service center after it has been dropped or subjected to other mechanical stresses. -
To avoid measurement errors, the receiving area must be kept clean.
-
Although the tool is designed for the tough conditions of jobsite use, as with other optical and electronic instruments (e.g. binoculars, spectacles, cameras) it should be treated with care.
-
Although the tool is protected against the entry of moisture, it should be wiped dry before being put away in its transport container.
-
Operation of the tool close to the ears may cause hearing damage. Do not position the tool close to the ears.
Electrical
- Keep the batteries out of reach of children.
- Do not allow the batteries to overheat and do not expose them to fire. The batteries may explode or release toxic substances.
- Do not charge the batteries.
- Do not solder the batteries into the tool.
- Do not discharge the batteries by short circuiting as this may cause them to overheat and swell up.
- Do not attempt to open the batteries and do not subject them to excessive mechanical stress.
Proper organization of the work area
- 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.
- Use the tool only within its specified limits.
Electromagnetic compatibility
Although the tool complies with the strict requirements of the applicable
directives, Hilti cannot entirely rule out the possibility of the tool being
subject to interference caused by powerful electromagnetic radiation, leading
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.
Likewise, Hilti cannot rule out the possibility of interference with other
devices (e.g. aircraft navigation equipment).
Before use
Inserting the batteries 1
CAUTION
Do not use damaged batteries.
DANGER
Do not mix old and new batteries. Do not mix batteries of different makes or
types.
-
Remove the batteries from the package and insert them in the tool (9).
NOTE Only batteries recommended by Hilti may be used to power the tool. -
Check that the battery terminals are positioned correctly as shown on the underside of each unit.
Operation
Switching the tool off and on 1
Press the on/off button (1).
Working with the laser receiver
The PMA 31 receiver can be used at distances of up to 30m from the laser tool.
The laser beam is indicated visually and by an audible signal.
Working with the horizontal line 1
- Switch the PMA 31 laser receiver on by pressing the on/off button (1).
- Hold the PMA 31 receiver in the laser beam with the receiving window at right angles to the projected plane of the line.
NOTE Results may be inaccurate if the receiving window is not held at right angles to the projected plane of the line.
Working with the vertical line 1
-
Check that the vertical line is projected at right angles to the wall (or working surface).
NOTE Results may be inaccurate if the vertical line is not projected at right angles to the wall or working surface. -
Switch the PMA 31 laser receiver on by pressing the on/off button (1).
-
Hold the PMA 31 receiver in the laser beam with the receiving window at right angles to the projected plane of the line.
NOTE Results may be inaccurate if the receiving window is not held at right angles to the projected plane of the line.
Settings
Signal volume adjustment (optional) 1
Set the desired volume level by pressing the audible signal adjustment button
(2).
NOTE
The volume is set to “normal” when the tool is switched on.
Each press of the button changes the volume in the sequence normal/loud / off.
Care and maintenance
Cleaning and drying
-
Blow dust off the surfaces.
-
Do not touch the display areas or the receiving window with the fingers.
-
Use only a clean, soft cloth for cleaning. If necessary, moisten the cloth slightly with pure alcohol or a little water.
NOTE Do not use any other liquids as these may damage the plastic components. -
Observe the temperature limits when storing your equipment. This is particularly important in winter/ summer if the equipment is kept inside a motor vehicle (-30°C to +60°C / -22°F to +140°F).
Storage
Remove the tool from its case if it has become wet.
The tool, its carrying case and accessories should be cleaned and dried (at
maximum 40°C / 104°F). Repack the equipment only once it has dried completely
and then store it in a dry place.
Check the accuracy of the equipment before it is used after a long period of
storage or transportation.
Remove the batteries from the tool before storing it for a long period.
Leaking batteries may damage the tool.
Transport
Use the Hilti toolbox or packaging of equivalent quality for transporting or
shipping your equipment.
DANGER
Always remove the batteries before shipping the tool.
Hilti calibration service
We recommend that the tool is checked by the Hilti calibration service at
regular intervals in order to verify its reliability in accordance with
standards and legal requirements.
Use can be made of the Hilti calibration service at any time, but checking at
least once a year is recommended.
The calibration service provides confirmation that the tool is in conformance,
on the day it is checked, with the specifications given in the operating
instructions.
The tool will be readjusted if deviations from the manufacturer’s
specification are found. After checking and adjustment, a calibration sticker
applied to the tool and a calibration certificate provide written verification
that the tool operates in accordance with the manufacturer’s specification.
Calibration certificates are always required by companies certified according
to ISO 900x.
Your local Hilti Center or representative will be pleased to provide further
information.
Disposal
DANGER
Improper disposal of the equipment may have serious consequences:
The burning of plastic components generates toxic fumes which may present a
health hazard.
Batteries may explode if damaged or exposed to very high temperatures, causing
poisoning, burns, acid burns or environmental pollution.
Careless disposal may permit unauthorized and improper use of the equipment.
This may result in serious personal injury, injury to third parties and
pollution of the environment.
Most of the materials from which Hilti tools or appliances are manufactured can be recycled. The materials must be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements fortaking back old tools and appliances for recycling. Ask Hilti customer service or your Hilti representative for further information.
For EC countries only
Do not dispose of electronic measuring tools or appliances together with
household waste.
In observance of the European Directive on waste electrical and electronic
equipment and its implementation in accordance with national law, electrical
appliances that have reached the end of their life must be collected
separately and returned to an environmentally compatible recycling facility.
Dispose of the batteries in accordance with national regulations.
