Intended use

The product described is a rotating laser with a visible rotating laser beam. It can be operated by one person. The tool is designed to be used to determine, transfer and check levels, verticals, slopes and right angles. Examples of its uses are: transferring datum lines and height marks, determining right angles for walls, vertical alignment on reference points and setting out slopes.

Use only the Hilti B12/2.6 and respectively the B 1230 Li ion battery for this product.
Use only the Hilti C 4⁄1250 charger for this product.

Features

The rotating laser can be used vertically, horizontally and for inclined planes.
The tool is equipped with the following operating status indicators: auto- leveling LED, inclined plane mode LED, surveillance mode LED and shock warning LED.

Auto-leveling

Auto-leveling takes place after the tool is switched on. LEDs indicate the current operating status. Auto leveling is active within the ±5° range relative to the horizontal plane and can be deactivated by pressing the button. The tool can be set up directly on the ground or floor, on a tripod, or with the aid of suitable mounting brackets.
Automatic alignment
Automatic alignment allows a single person to bring the laser plane into alignment with the laser receiver. The rotating laser tool detects the applicable direction of alignment as follows:

Horizontal in conjunction with the PRA 90 automatic tripod and PRA 30 laser receiver.
Inclination in conjunction with the PRA 30 laser receiver, and (optional) with the PRA 79 slope adapter.
Vertical in conjunction with the PRA 30 laser receiver.

Inclination angle
The inclination can be set by the following means:

Manual entry of the values at the PRA 30 laser receiver
Automatic alignment of the rotating laser with the PRA 30 laser receiver
Presetting an inclination through use of the PRA 79 slope adapter

The angle of inclination can be read from the laser receiver.

Surveillance when working in the vertical plane

The rotating laser monitors alignment of the laser plane in combination with the PRA 30 laser receiver. In the event of deviations in alignment, laser rotation stops for 40 seconds. During this time the tool corrects all errors caused by temperature fluctuations, wind or other influences. Laser rotation restarts after this automatic correction. If necessary, the surveillance function can be deactivated.

Automatic switch-off

The tool switches off automatically if it is unable to level itself because the laser:

• Is inclined at more than 5° relative to the horizontal plane (except in inclined plane mode).
• Is blocked mechanically.
• Has been knocked off level by an impact or vibration.

When the tool has switched itself off, rotation stops and all LEDs flash.

Shock warning function

If the laser is knocked off level during operation, the built-in shock warning function switches the tool to warning mode. The shock warning function does not go active until two minutes after completion of auto leveling. If a button on the control panel is pressed within this two-minute period it will take a further two
minutes for the shock warning function to go active. If the laser is in warning mode:

All LEDs flash.
The laser stops rotating.
The laser beam switches off.

The shock warning function can be switched off by pressing the button if the ground or floor is not free from vibration or when you are working in inclined plane mode.

Deactivate the shock warning function. → page 32

Laser receiver / remote control unit

Hilti laser receivers digitally indicate the distance between the marking notch on the laser receiver and the position at which the laser beam (laser plane) strikes the detection area on the receiver. The laser beam can also be received over long distances. The PRA 30 can be used as a laser receiver and also as a remote
control unit for the rotating laser. The system of units and the unit of measurement can be set as desired.

Set the units that are to be used. → page 34
Change the units used by the laser receiver. → page 34

Pairing accessories and device

Pairing is the act of enabling accessories and devices to communicate with each other by wireless. The rotating laser and the laser receiver are already paired when supplied. This helps ensure trouble-free operation within the vicinity of other wireless devices. Additional laser receivers or PRA 90 automatic tripods cannot be used without first being paired.

Checking the main and transverse horizontal axes 14

Set up the tripod approx. 20 m (66 ft) from a wall and adjust the tripod head horizontally with a spirit level.
Mount the tool on the tripod and use the visual sighting method (front and rear sights) to aim the tool at the wall.
Fig. a: Use the receiver to catch the laser beam and mark a point (point 1) on the wall.
Pivot the tool clockwise through 90° about its own axis. In doing so, ensure that the height of the tool does not change.
Fig. b: Use the laser receiver to catch the laser beam and mark a second point (point 2) on the wall.
Fig. c and d: Repeat the two previous steps twice and use the laser receiver to catch the beam and mark points 3 and 4 on the wall.

If the procedure has been carried out accurately, the vertical distance between the two marked points 1 and 3 (main axis) or points 2 and 4 (transverse axis) should each be < 2 mm (at 20 m) (0.12″ at 66 ft). If the deviation is greater than this, please return the tool to Hilti Service for calibration.

Checking the vertical axis 15
