3.1 Product overview
3.2 Intended use
The product described is an automatic tripod onto which a rotating laser can be fitted. The tripod can be
moved in height using the control panel or a remote control unit. Using the tripod and the rotating laser
fitted to it, a horizontal laser plane can be established which is directed onto a particular target height, meter
marks can be transmitted and horizontal heights aligned and checked.
▶ Use only the Hilti PRA 84 Li-ion battery for this product.
▶ For these batteries, use only the Hilti PRA 85 AC adapter.
The tripod can be operated in two different ways: by means of the control panel directly on the tripod, or with
a Hilti laser receiver/remote control unit (in combination with a Hilti rotating laser for automatic alignment
and monitoring).
Compatible laser receivers/remote control units:
• PRA 30
• PRA 30G
• PRA 300
3.3 Automatic alignment
The tripod can be automatically aligned with the HiltiPR 30­HVS A12, PR 30­HVSG A12 or the PR 300­HV2S
rotating laser. These rotating lasers are specifically matched to the PRA 90 and support three-device
communication between tripod, rotating laser and associated laser receiver/remote control unit.
Using these three components together, a laser plane can be aligned onto a precise point automatically.
Only the target height has to be indicated with the laser receiver/remote control unit and the PRA 90 moves
the laser plane of the rotating laser exactly to this height.
Automatic alignment is not possible when other rotating lasers are used.
