3.1.5 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 B 12⁄2.6 Li-Ion battery for this product.
▶ Use only the Hilti C 4⁄12­50 charger for this product.
3.1.6 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-
