7.1.2.3 Switching on all beams
Press the selector button three times.
7.1.3 Switching off the tool / laser beams
Press the selector button until the laser beam is no
longer visible and the LED goes out.
NOTE
en
The tool switches itself off automatically after approx.
15 min.
7.1.4 Deactivating the automatic power-off
Press and hold the selector button for approx. 4 sec.
until the laser beam blinks three times as confirma-
tion.
NOTE
The tool will be switched off when the selector button
is pressed (between one and three times, depend-
ing on operating status) or when the batteries are
exhausted.
7.1.5 Using the tool with the PMA 30 laser
receiver
For further information, please refer to the PMA 30
operating instructions.
7.2 Examples of applications
7.2.1 Vertical alignment of pipes 3
7.2.2 Marking out the position of light fittings 4
7.2.3 Setting out drywall track for a partition
wall 5
7.2.4 Setting out a raised floor 6
7.3 Checking
7.3.1 Checking the vertical (plumb point) 7
1. Make a mark on the floor (a cross) in a high room
(e.g. in a stairwell or hallway with a height of 5–10
m).
2. Place the tool on a smooth, level (horizontal)
surface.
3. Switch the tool on.
4. Position the tool with the lower beam on the
center of the cross.
5. Mark the position of the vertical beam on the
ceiling. Attach a piece of paper to the ceiling
before making the mark.

6. Pivot the tool through 90°.
NOTE The lower plumb beam must remain on
the center of the cross.
7. Mark the position of the vertical beam on the
ceiling.
8. Repeat the procedure after pivoting the tool
through 180° and 270°.
NOTE The resulting 4 marks form a circle in
which the intersection of the diagonals d1 (1 –
3) and d2 (2 – 4) marks the exact center of the
plumb point.
7.3.1.1 Calculation of accuracy
10 (d1 + d2) [mm]
R = x
RH [m]
30 (d1 + d2) [inch]
R = x
RH [ft]
The result (R) provided by this formula (RH = room
height) refers to the tool's accuracy "in mm at 10 m"
(formula (1)). This result (R) should be within the
specification for the tool (3 mm at 10 m).
7.3.2 Checking the laser line point of
intersection for height deviation 8
1. Place the tool on a smooth, level surface approx.
20 cm from the wall (A) with the laser beam
directed toward the wall (A).
2. Mark the point of intersection of the laser lines on
the wall (A) with a cross.
3. Pivot the tool through 180° and mark the point of
intersection of the laser lines on the opposite wall
(B) with a cross.
4. Place the tool on an even, level surface approx. 20
cm from the wall (B) with the laser beam directed
toward the wall (B).
5. Mark the point of intersection of the laser lines on
the wall (B) with a cross.
6. Pivot the tool through 180° and mark the point of
intersection of the laser lines on the opposite wall
(A) with a cross.
7.3.2.1 Calculation of accuracy
1. Measure the distances d1 between 1 and 4 and
d2 between 2 and 3.
