Operating Modes; Automatic Levelling - Bosch Professional GLL 2-10 Manual Original

28 | English
To switch the measuring tool back on after it has been automatically switched off, you
can either slide the on/off switch (2) to the "Off" position first and then switch the meas-
uring tool back on, or press either the vertical mode button (5) or the horizontal mode
button (6) once.
To deactivate automatic shut-off, hold down the horizontal mode button (6) for at least
three seconds (with the measuring tool switched on). If automatic shut-off is deactiv-
ated, the laser lines will flash briefly as confirmation.
Note: If the operating temperature exceeds 45 °C, automatic shut-off can no longer be
deactivated.
To activate the automatic shut-off function, switch the measuring tool off and on again.

Operating Modes

The measuring tool has several operating modes, which you can switch between at any
time:
– Cross-line mode (see figure C): Generates one horizontal and one vertical laser line
– Horizontal mode (see figure D): Generates one horizontal laser line
– Vertical mode (see figure E): Generates one vertical laser line
After switching on, the measuring tool is in cross-line operating mode. Using the buttons
for horizontal mode (6) and vertical mode (5), you can switch the horizontal and vertical
laser lines on and off independently of one another.
All operating modes can be selected with both automatic levelling or the pendulum lock.

Automatic Levelling

Working with automatic levelling
Position the measuring tool on a level, firm surface or attach it to the rotating mount (13)
or the tripod (23).
For work with automatic levelling, slide the on/off switch (2) to the " On" position.
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 moving.
If automatic levelling is not possible, e.g. because the surface on which the measuring
tool stands deviates by more than 4° from the horizontal plane, the laser beams will flash
quickly.
If this is the case, set up the measuring tool in a level position and wait for the self-level-
ling to take place. As soon as the measuring tool is within the self-levelling range of ±4°,
the laser beams will light up continuously.
