Hilti PR 2-HS A12 Mode D'emploi Original page 23

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.
• has been knocked off level by an impact or vibration.
When the tool has switched itself off, rotation stops and all LEDs blink.
Shock warning
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 becomes active only two minutes after completion of auto-
leveling. If a button on the control panel is pressed within this two-minute period it will again take a further
two minutes until shock warning function becomes active. If the laser is in warning mode:
• all LEDs blink.
• the laser stops rotating.
• the laser beam switches off.
The shock warning function can be switched off by pressing the
from vibration or when you are working in inclined plane mode.
Laser receiver
Hilti laser receivers can be used to detect and indicate the laser beam at great distances.
