laser on.
4. Now you can tilt the laser to the angle you
require, so that the lines are displayed
diagonally on the wall as shown in Fig. D2.
5. To switch off , press the ON / OFF button (1).
5. MAINTENANCE
Accuracy check
Only the centre of the laser line must be
used for marking. The width of the laser line
changes depending on the distance.
Quick horizontal line check (Fig. A, E1)
1. Set the device at approximately 5 meters from
the wall.
2. Slide the lock switch (2) to the right. Press the
ON / OFF button (1) on the device to power on.
If the laser flashes, the permissible inclination
range of 5 degrees is exceeded. Position the
device horizontally until the laser stops flashing.
3. After it self-levels, make a horizontal mark on the
wall as shown in figure E1. Label this as point A.
4. Turn the laser 2.5 m to the right.
5. Turn the laser on, and after it self-levels, make a
horizontal mark on the wall. Label this as point
B as shown in figure E1. When points A and
B are more than 2.5mm apart from a vertical
perspective, a calibration check is necessary.
Quick vertical line check (Fig. A, E2)
1. Set the device at approximately 5 meters from
the wall.
2. Hang a 2.5 meter rope on the wall with a weight
on the end of the rope as shown in figure E2.
The rope must be able to swing freely.
3. Slide the lock switch (2) to the right. Press the
ON / OFF button (1) on the device to power on.
Position the vertical line next to the wire. If the
laser flashes, the permissible inclination range
of 5 degrees is exceeded. Position the device
horizontally until the laser stops flashing. After
it self-levels, the difference must not exceed ±
2.5 mm. When it's more than 2.5mm apart, a
calibration check is necessary.
Calibration check (Fig. A, F)
The accuracy of the horizontal beam can be
checked by following these steps:
1. Set the device on a tripod, centered in a room
with walls ideally 5 meter away.

2. Slide the lock switch (2) to the right. Press the
ON / OFF button (1) on the device to power on.
If the laser flashes, the permissible inclination
range of 5 degrees is exceeded. Position the
device horizontally until the laser stops flashing.
3. After it self-levels, make a horizontal mark on
the wall anywhere along the horizontal line to
indicate the height of the beam. Label this as
point A as shown in Fig. F1.
4. Turn the device 180°, and after it self-levels,
mark point B as shown in Fig. F2.
5. Turn the device 180°. Position the device as
near as possible to the wall at the height of
point A as shown in Fig. F3.
6. Turn the device 180°, and after it self-levels,
mark point C. This mark should either be
directly above, below or on top of point B as
shown in Fig. F4. The difference between points
B and C is the tolerance. When B and C are
more than 0.5 mm/ m apart, an adjustment is
necessary. Contact your authorized dealer or
else the Vonroc Service Department.
