Switching On And Off; Operating Modes - Bosch GLL 2-15 Instrucciones De Funcionamiento Y Seguridad

Initial Operation
Protect the tool against
WARNING
!
moisture and direct sun
irradiation.
Do not subject the tool to extreme
temperatures or variations in
temperature. As an example, do not leave
it in vehicles for longer periods. In case of
large variations in temperature, allow the tool
to adjust to the ambient temperature before
putting it into operation. In case of extreme
temperatures or variations in temperature, the
accuracy of the tool can be impaired.
Avoid heavy impact or falling of the tool.
After heavy exterior impact on the tool, an
accuracy check should always be carried
out before continuing to work (see "Leveling
Accuracy").
Switch the tool off during transport. When
switching off, the leveling unit, which can be
damaged in case of intense movement, is
locked.
Switching On and Off
To switch on the tool, slide the On/Off switch
3 to the "On" position. Immediately after
switching on, the tool sends laser beams out of
the exit openings 1.
Do not point the laser beam at persons or
animals and do not look into the laser beam
yourself, not even from a large distance.
To switch off the tool, slide the On/Off switch
3 to the "off" position. When switching off, the
leveling unit is locked.
Do not leave the switched on measuring
tool unattended and switch the tool off
after use. Other persons could be blinded by
the laser beam.
The tool switches off automaically after an
operating duration of 2 hours.
Operating Modes
The tool has total of four operation modes that
can be switched through in sequence
In any of the first three operation modes
(Automatic Self-Leveling), if the tool is tilted
more than 4° in any direction, the laser lines will
blink slowly (Out-Of-Level error) to indicate the
tool is currently not self-leveling.
Bring the tool to a more level position before
continuing work.
Operation
– Horizontal operation "–": Produces a
horizontal laser line,
– Vertical operation "l": Produces a vertical
laser line,
– Cross-line operation "+": Produces a
horizontal and vertical laser line.
The tool has one Slope mode that projects a
crossline. The operating mode indicator 21 will
illuminate while Slope mode is selected. The
tool will not indicate Out-Of-Level (OOL) in
Slope mode.
After switching on, the tool is in cross-line
operating mode with self-leveling. To change
the operating mode, press the operating mode
button 4.
If the self-leveling indicator 21 light is red, the
line laser is in the operating mode without
self-leveling. In this mode the laser lines
will permanently display regardless of the
inclination of the line laser.
Working with Automatic Leveling
Position the tool on a level and firm support,
attach it to the magnetic bracket 10 or to a
tripod.
After switching on, the leveling function
automatically compensates irregularities within
the self-leveling range of ±4°. The leveling is
finished as soon as the laser beams do not
move anymore.
If the automatic leveling function 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
flash slowly. In this case, bring the tool to the
level position and wait for the self-leveling to
take place. As soon as the tool is within the
self-leveling range of ±4°, the laser lines light up
continuously again.
In case of ground vibrations or position changes
during operation, the tool is automatically
leveled in again. To avoid errors, check the
position of the horizontal and vertical laser
line with regard to the reference points upon
re-leveling.
