Leveling Accuracy - Bosch GLL 150 E LR 3 Instrucciones De Funcionamiento

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.

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 one operating mode:
– Horizontal operation: generates a pulsed
horizontal laser plane.
After switching on, the tool is in horizontal
operation.
Pulse Function
To work with the laser receiver 10, the pulse
function is always activated.
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, by
attaching it to the tripod 13.
Push the On/Off switch 2 to the "on" position.
Influences on Accuracy
The ambient temperature has the greatest
influence. Especially temperature differences
occurring from the ground upward can divert
the laser beam.
Because the largest difference in temperature
layers is close to the ground, the tool should
always be mounted on a tripod when distances
exceeding 65 ft (20 m). If possible, also set up
the tool in the center of the work area.
Apart from exterior influences, device-specific
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 rapidly.
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.
Place the unit so that it cannot self-level. When
automatic leveling is switched off, the laser will
flash for the first 30 s until it turns into a solid
line.
When the automatic leveling is switched off,
the tool can be held by hand or placed on an
inclined surface. In cross-line operation, the
do not necessarily run at a right angle to each
other.
!
The size of the laser point changes with the
distance.
Leveling Accuracy
influences (such as heavy impact or falling
down) can lead to deviations. Therefore, check
the accuracy of the tool each time before
starting your work.
Should the tool exceed the maximum deviation
during one of the tests, please have it repaired
by a Bosch after-sales service.
Checking the Horizontal Leveling Accuracy.
A free measuring distance of 16 ft (5 m)on a
firm surface in front of two walls A and B is
required for the check.
