Setting Up The Tool 8; Setting Up Over A Pipe Using The Laser Plummet 9; Operation; Measuring Using The Horizontal Circle - Hilti POT 10 Operating Instructions Manual

7.5.2 Setting up the tool 8

1. Set up the tripod with the center of the tripod head approximately over the point marked on the ground.
2. Mount the tool on the tripod (tighten the screw).
3. Move two of the tripod legs with your hands until the laser beam strikes the mark on the ground.
NOTE Take care to ensure that the tripod head remains approximately horizontal.
4. Then press the points of the tripod legs into the ground by applying pressure with your foot.
5. Adjust the footscrews to eliminate any deviation of the laser point from the mark on the ground. The laser point
must then be exactly in the center of the mark on the ground.
6. The circular bubble level can be centered by adjusting the tripod legs.
NOTE This is done by extending or retracting the leg at the opposite side of the tripod, depending on the direction
in which the bubbles is to be moved. This process may have to be repeated several times until the desired result
is achieved.
7. Once the circular bubble level has been centered, align the laser plummet exactly with the mark on the ground
by shifting the position of the tool laterally on the tripod plate.
8. Following this, position the tubular bubble level parallel to two footscrews and center the bubble.
9. Rotate the tool through 90° and, with the aid of the third footscrew, center the bubble. Then rotate the tool again
through 90° and readjust with the footscrews if necessary until the bubble is centered.

7.5.3 Setting up over a pipe using the laser plummet 9

Pipes are often used to mark points on the ground.
In this case, the laser beam is projected into the pipe and the point cannot be seen.
Lay a piece of paper, plastic foil or other semi-translucent material on the pipe in order to make the laser point visible.

8 Operation

8.1 Measuring using the horizontal circle

8.1.1 Zeroing before reading from the horizontal circle

The horizontal circle can be zeroed at any time by pressing the 0- SET button, thereby setting the reference point for
the horizontal circle.

8.1.2 Changing the direction of angle measurement with the horizontal circle

The direction of measurement for horizontal angles can be switched between right (clockwise) and left (counterclock-
wise) by pressing the R/L button.
