Initial Operation; Automatic Leveling - Bosch GLL 150 E Operating/Safety Instructions Manual

Initial Operation
An accuracy check should always be carried
out before use.
Protect the tool against
! WARNING
moisture and direct
sun light.
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 dropping 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 2
to the "on". position. Immediately after switching
on, the tool sends laser beams out of the exit
opening 1.
Align arrow of ON-OFF
! CAUTION
switch directly below
ON position. If ON -OFF switch is not fully
engaged, self-leveling feature is not activated
and laser line will be out of level.
To switch off the tool, slide the On/Off switch
2 to the "off" position. When switching off, the
leveling unit is locked.
Do not point the laser beam
! WARNING
at persons or animals and
do not look into the laser beam yourself, not
even from a large distance.
Do not leave the switched on tool
unattended and switch the tool off after use.
Operating Modes
The tool has two operating mode:
- Horizontal operation: generates a self-
leveled, horizontal plane that's pulsed. The
LR 3 laser receiver can be used.
Operation
- Slope operation: generates a sloped
plane for indoor work at an angle. Pulse
is deactivated and the LR 3 laser receiver
cannot be use
Pulse Function
To work with the laser receiver 10, the pulse
function is activated when using the tool in
horizontal operation.
With the pulse function, the laser lines flash
at very high frequency and thus become
detectable by the laser receiver 10.
Automatic Leveling
Working with Automatic Leveling
Position the tool on a level and firm support,
such as the BT 152 tripod 13.
Push the On/Off switch 2 to the "on" position.
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 any more.
If automatic leveling is not possible, e.g.
because the surface on which the tool stands
deviates by more than 4° from the horizontal
plane, the laser lines begin to flash.
Set up the tool in 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
beam lights up continuously.
In case of ground vibrations or position changes
during operation, the tool is automatically
re-leveled. To avoid errors, check the position
of the horizontal laser line with regard to the
reference point upon releveling.
Working without Automatic
Tilt the unit so the line is projected at the angle
you need it. The laser will flash for the first 30 s
until it turns into a solid line.
CAUTION
!
The thickness of the laser line changes with the
distance.

Working Advice
Always use the center of
the laser beam for marking.
