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 for determining, transferring and checking references in the horizontal and
inclined planes. Examples of uses are transferring datums and heights.
▶ 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 horizontally and for inclined planes.
The tool is equipped with the following operating status indicators: auto-leveling LED, inclination angle LED
and shock warning LED.
Auto-leveling
Auto-leveling is carried out by two built-in servo motors after switching 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
with the aid of suitable mounting brackets.
Inclination angle
Alternatively, in inclined plane mode, the slope adapter can be adjusted manually to achieve slopes of up to
60%. Auto-leveling is not active.
Automatic cut-out
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.
• is blocked mechanically.
