7. Operation

7.1 Operation
en
7.1.1 Switching on the laser beams
Activate the tool by pressing the on/off button once.
This switches on all laser beams (plumb beam, front
beam and perpendicular beam).
7.1.2 Switching off the tool / laser beams
Press the on/off button until the laser beam is no
longer visible and the LED goes out.
NOTE
The tool switches itself off automatically after approx.
15 min.
7.1.3 Deactivating the automatic cut-out
Press and hold the selector button down for approx.
4 sec. until the laser beams blink three times as
confirmation.
NOTE
The tool is switched off when the selector button is
pressed (between one and three times, depending on
operating status) or when the batteries are exhausted.

7.2 Examples of applications

7.2.1 Vertical alignment of sections of a steel
structure 3
7.2.2 Vertical alignment of door and window
frames 4
7.2.3 Alignment of drywall track for a partition
wall 5
7.2.4 Alignment of pipe fastenings 6
7.3 Checking
7.3.1 Checking the vertical (plumb) beam 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 reference 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 define 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
R = x
RH [m]
30
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 forward beam and/or
perpendicular beam 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 center of the laser beam on the wall (A)
with a cross.
