Setting The Inclination Using The Pra 79 Slope Adapter - Hilti PR 30-HVS A12 Manual De Instrucciones

1. Use the visual sighting method on the head to line up the vertical axis of the rotating laser.
2. Press the
button on the rotating laser.
◁ The rotating laser levels itself and then projects a stationary downward-pointing laser beam.
3. Position the rotating laser so that the projected laser beam strikes reference point (A) exactly. Please
note: The reference point is not a plumb point!
4. To shift the laser plane to the right or left, press the
◁ The rotating laser begins rotating after pressing one of the two direction arrow buttons.
5.8 Automatic vertical alignment
The rotating laser is placed or securely mounted in the vertical position (tripod, wall mount, facade or
batter board adapter, or lying on the rear grips). A reference point (A) is marked below the laser head
(e.g. a nail on a batter board or a spot of paint on the floor or ground).
The PRA 30 laser receiver and the rotating laser are paired.
The PRA 30 laser receiver and the receiving side of the rotating laser are facing each other and in direct
line of sight. The best receiving side of the rotating laser is the side at which the battery is inserted.
1. Use the visual sighting method on the head to line up the vertical axis of the rotating laser.
2. Press the
button on the rotating laser.
◁ The rotating laser levels itself and then projects a stationary downward-pointing laser beam.
3. Position the rotating laser so that the projected laser beam strikes reference point (A) exactly. Please
note: The reference point is not a plumb point!
4. Keep the marking notch on the PRA 30 laser receiver on the plane that is to be set. The PRA 30 laser
receiver should be held steady or secured in place.
5. Begin automatic alignment by double-clicking the
◁ The head of the rotating laser pivots to the left and right until the desired position is reached. A signal
tone is emitted repeatedly during this procedure.
◁ The rotating laser levels itself once the position has been reached. Successful completion is indicated
by a continuous signal tone with a duration of 5 seconds. The
◁ The rotating laser switches to surveillance mode. Surveillance when working in the vertical plane
→ page 25
▽ If automatic alignment cannot be completed successfully, short signal tones are emitted and the
symbol disappears.
6. Do NOT remove the PRA 30 laser receiver from the target plane so long as surveillance mode is active.
7. Double-click the
button on the PRA 30 laser receiver.
◁ During automatic alignment: Stops automatic alignment before completion.
◁ In surveillance mode: Ends surveillance mode.

Setting the inclination using the PRA 79 slope adapter

Depending on the application, the PRA 79 slope adapter can be mounted on a tripod. The angle of
inclination of the PRA 79 slope adapter is set to 0°.
1. Mount the rotating laser on the PRA 79 slope adapter. Observe the operating instructions for the PRA 79
slope adapter. The control panel of the rotating laser should be facing you.
2. Position the rotating laser either at the upper edge or lower edge of the inclined plane.
3. Press the
button on the rotating laser.
◁ The laser switches on, the beam begins to rotate and the "auto leveling" LED lights as soon as the
tool has leveled itself.
4. Press the
button on the rotating laser.
◁ The inclined plane mode LED on the rotating laser then blinks.
5. Set the PRA 79 slope adapter to the desired angle of inclination.
When the angle of inclination is set manually, the rotating laser levels the laser plane once and then
fixes it. Vibration, changes in temperature or other influences that may occur during the course of
the day may affect the position of the laser plane.
