 Description

2.1 Use of the product as directed
The Hilti PRA 30 / 31 laser receiver is designed to detect the laser beam from rotating lasers.
Observe the information printed in the operating instructions concerning operation, care and maintenance.
Take the influences of the surrounding area into account. Do not use the tool where there is a risk of fire or explosion. Modification of the tool or tampering with its parts is not permissible.
2.2 Features
The tool can either be held by hand or, using the corresponding holder, mounted on a measuring staff, telescopic staff, leveling staff, wooden batten or frame etc.
2.3 Indicators
NOTE
The display of the PRA 30 / 31 laser receiver uses several symbols to indicate various modes or statuses.

Display showing the position of the eceiver relative to the height of the laser plane| The position of the receiver relative to the height of the laser plane is shown by an arrow indicating the direction in which the receiver has to be moved in order to bring it exactly into alignment with the laser.
---|---
Battery status indicator| The battery status indicator shows the remaining battery capacity.
Volume level| When no volume level symbol is visible in the display, the volume level is set to zero (off). If 1 column is shown, the volume is set to “quiet”. If 2 columns are shown, the volume is set to “normal”. If 3 columns are shown, the volume is set to “loud”.
PRE 3 battery status indicator| The PRE 3 symbol is shown in the display (only if the PRA 30 / 31 is receiving a signal from the PRE 3) when the PRE 3 battery requires charging.
Units indicator| Shows the exact distance of the receiver from the laser plane in the desired measuring units.

 Safety instructions

4.1 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.
4.2 General safety rules
a) Keep other persons, especially children, away from the area in which the work is being carried out.
b) Check the condition of the tool before use. If the tool is found to be damaged, have it repaired at a Hilti service center.
c) Do not render safety devices ineffective and do not remove information and warning notices.
d) The tool must be checked at a Hilti service center after it has been dropped or subjected to other mechanical stresses.
e) If mounting on an adapter, check that the tool is fitted correctly.
f) To avoid measurement errors, the receiving area must be kept clean.
g) Although the tool is designed for the tough conditions of jobsite use, as with other optical and electronic nstruments (e.g. binoculars, spectacles, cameras) it should be treated with care.
h) 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.
i) To avoid hearing damage, hold the tool as far away as possible from your ear (and other per- sons’ ears).
4.2.1 Electrical

a) Keep the batteries out of reach of children.
b) Do not allow the batteries to overheat and do not expose them to fire. The batteries may explode or release toxic substances.
c) Do not charge the batteries.
d) Do not solder the batteries into the tool.
e) Do not discharge the batteries by short circuiting as this may cause them to overheat and present a risk of personal injury (burns).
f) Do not attempt to open the batteries and do not subject them to excessive mechanical stress.
4.3 Proper organization of the work area
a) Avoid unfavorable body positions when working on ladders or scaffolding. Make sure you work fromasafestanceandstayinbalanceatall times.
b) Measurements taken through or from panes of glass or through other objects may be inaccurate.
c) Use the tool only within its specified limits.
d) Use of the telescopic staff in the vicinity of over- head high voltage cables is not permissible.
4.4 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).

Beforeuse

5.1 Inserting the batteries
CAUTION
Do not use damaged batteries.
DANGER

1. Open the catch on the PRA 80.
2.  Insert the PRA 30 / 31 laser receiver in the PRA 80 laser receiver holder.
3. Close the catch on the PRA 80.
4.  Switch the laser receiver on by pressing the on / off button.
5.  Rotate the grip to bring it into the open position.
6.  Secure the PRA 80 receiver holder on the telescopic staff or leveling staff by turning the rotating grip.
7. Hold the PRA 30 / 31 with the receiving window directly in the plane of the rotating laser beam. The laser beam is indicated by visual and audible signals.

6.2.3 Working with the PRA 81

1. Open the locking mechanism on the PRA 81.
2. Insert the PRA 30 / 31 laser receiver in the PRA 81 height transfer device.
3. Close the locking mechanism on the PRA 81.
4. Switch the laser receiver on by pressing the on / off button.
5.  Hold the PRA 30 / 31 with the receiving window directly in the plane of the rotating laser beam. The laser beam is indicated by visual and audible signals.
6. Use the measuring tape to measure the desired offset distance.

6.2.4 Menu options
When switching the PRA 30 / 31 on, press and hold the on / off button for two seconds.
The menu is then shown in the display.
