2.3 Horizontal plane
After switching on, the tool levels itself automatically by way of 2 built-in servo motors.
2.4 Vertical plane (automatic leveling)
Vertical alignment is carried out automatically. The +/- buttons on the PRA 2 remote control unit can be used to bring
the vertical plane manually into alignment (rotate).
2.5 Slope
In inclined plane mode, the PRA 2 remote control unit can be used to manually adjust the slope by up to ± 5°.
Alternatively, in inclined plane mode, the slope adapter can be used to achieve slopes of up to 60%.
2.6 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.
2.7 Automatic cut-out
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 if leveling is unsuccessful (when the tool is set up outside its self-leveling range or movement
is blocked mechanically).
The tool switches itself off when knocked off level (vibration / impact).
When the tool has switched itself off, rotation stops and all LEDs blink.
2.8 Combination with the PRA 2 remote control unit
The PRA 2 remote control unit can be used to control the rotating laser conveniently from a distance. The remote
control function can also be used to adjust alignment of the laser beam.
2.9 Operation in combination with Hilti laser receivers
Hilti laser receivers can be used to detect and indicate the laser beam at great distances. For further information,
please refer to the operating instructions for the laser receiver.
NOTE
Depending on the version purchased, the laser receiver may not be included among the items supplied.
2.10 Speed of rotation
3 speeds of rotation are available for use (300, 600, 1500 /min).
2.11 Increasing the visibility of the laser beam
Depending on the working distance and ambient light, visibility of the laser beam may be impaired.
Visibility of the laser beam can be improved with the aid of the target plate and/or the laser visibility glasses.
When laser beam visibility is reduced due to bright sunshine, for example, we recommend use of the laser receiver
(accessory).
