Automatic Levelling; Working Advice - Bosch Quigo Green Originalbetriebsanleitung

Switching on/off
To switch on the measuring tool, push the on/off switch (4) up. Immediately
after switching on, the measuring tool sends two laser lines out of the outlet
aperture (5).
To switch off the measuring tool, push the on/off switch (4) downward over
the laser beam outlet aperture (5).
Never leave the measuring tool unattended when switched on, and
u
ensure the measuring tool is switched off after use. Others may be
blinded by the laser beam.

Automatic levelling

Position the measuring tool on a level, firm surface or attach it to the
holder (16) or the tripod (6). To work with automatic levelling, the under-
side of the measuring tool needs to be horizontal and aligned with the tripod
mount (8) facing down. After switching on, the automatic levelling function
automatically compensates irregularities within the self-levelling range of
±4°. The levelling is finished as soon as the laser lines stop flashing.
If automatic levelling is not possible, e.g. because the underside of the
measuring tool deviates by more than 4° from the horizontal plane or the
measuring tool is held freely in the hand, the laser lines will continuously
flash slowly and the measuring tool will work without automatic levelling.
The laser lines remain switched on, but the two intersecting lines will no
longer necessarily be perpendicular to each other. To make sure that the two
laser lines are still perpendicular to one another, position the measuring tool
at an angle of 90° to the wall.
In case of ground vibrations or position changes during operation, the meas-
uring tool is automatically levelled again. Upon re-levelling, check the posi-
tion of the horizontal or vertical laser line with regard to the reference points
to avoid errors by moving the measuring tool.

Working Advice

Only the centre of the laser line must be used for marking. The width
u
of the laser line changes depending on the distance.
Attaching using the holder (see figure A)
Using the holder (16), you can attach the measuring tool to various objects
up to 10 to 60 mm thick, e.g. to vertical or horizontal boards or pipes.
