Hilti PRE 3 User Manual

2.4 Inclined plane (manual alignment in the desired plane of inclination)
The desired inclination can be set with the aid of the PRA 78 slope adapter. For further information on using
the slope adapter, please refer to the instruction sheet supplied with the PRA 78.
2.5 Shock warning
The built-in shock warning function (becomes active one minute after completion of auto-leveling). The tool
goes into warning mode if it is knocked off level (due to vibration or impact) while in operation: all LEDs blink;
the head of the laser stops rotating; The laser beam is switched off.
2.6 Automatic cut-out
The laser does not switch on and all LEDs blink if the tool is set up outside its self-leveling range or movement
is blocked mechanically. The tool can be set up on a tripod with a 5/8" thread or stood directly on some other
steady surface (free of vibration). When automatic leveling is activated for one or both axes, the built-in servo
system ensures that the specified accuracy is maintained. The tool switches itself off when automatic leveling
cannot be achieved (tool set up outside its leveling range or physical impediment of the mechanism) or when
knocked off level (see “Shock warning” section).
NOTE
If the correct level cannot be achieved, the laser switches itself off and all LEDs blink.
