VONROC LL503DC Bersetzung Der Originalbetriebsanleitung Seite 11

Switch the measuring tool off when
transporting it. The pendulum unit is locked
when the tool is switched off, as it can
otherwise be damaged.
Manual mode (Fig. A, B, F)
The laser can be aligned manually to the angle you
require, to enable for example a diagonal line to be
displayed.
1. Place the laser on a flat surface or fit it to the
magnetic bracket (7) or tripod (not included)
and fasten it as described above.
2. Check if the lock switch (3) is set to the left. If
not, slide the lock switch (3) to the left.
3. Press the ON / OFF button (1) on the device to
power on. The operating mode LED (6) lights up
red, because the pendulum is blocked.
- LL503DC and LL504DC have two 360° lines
as show in figure F1. One horizontal line
and one front vertical line. Each laser line is
powered on by pressing its ON/OFF button
(1,2) on the keypad or remote control (11).
The laser lines can be powered one at a time
or all at the same time.
- LL505DC and LL506DC have three 360° lines
as show in figure F2. One horizontal line,
one front vertical line and one side vertical
line. The horizontal laser line is powered on
by pressing its ON/OFF button (1) on the
keypad or remote control (11). The vertical
front laser line is powered on by pressing its
ON/OFF button (2) on the keypad or remote
control (11). Pressing two times the ON/
OFF button (2) for the vertical side laser and
three times for both vertical lasers. The laser
lines can be powered one at a time or all at
the same time.
4. Now you can tilt the laser to the angle you re-
quire, so that the lines are displayed diagonally
on the wall, ground or ceiling.
5. Hold down the ON/OFF button (1) to switch off
the equipment.
Laser target plate (Fig. A)
The laser target plate (21) improves visibility of
the laser beam during unfavourable environmental
conditions (e.g. direct sunlight) and at greater dis-
tances. The reflective part of the laser target plate
(21) improves visibility of the laser.

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, G1)
1. Set the device at approximately 5 meters from
the wall.
2. Slide the lock switch (3) to the right to switch
the device on. When the laser beam flashes and
the device starts to beep, the permissible incli-
nation range of 4 degrees is exceeded. Position
the device horizontally.
3. After it self-levels, make a horizontal mark on the
wall as shown in figure G1. 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 G1. 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, G2):
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 G2.
The rope must be able to swing freely.
3. Slide the lock switch (3) to the right to switch
the device on. The vertical front laser line is
powered on by pressing its ON/OFF button (2)
on the keypad or remote control. Pressing two
times the ON/OFF button(2) for the vertical side
laser (LL505DC and LL506DC only). Position
the vertical line next to the wire. When the laser
beam flashes and the device starts to beep, the
permissible inclination range of 4 degrees is
exceeded. Position the device horizontally. 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, H)
The accuracy of the horizontal beam can be chec-
ked 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 (3) to the right to switch
the device on. When the laser beam flashes and
