Working Advice - Bosch GLL 2-20 Instrucciones De Funcionamiento Y Seguridad

Because the largest difference in temperature
layers is close to the ground, the tool should
always be mounted on a tripod when using for
distances exceeding 65 ft. If possible, also set
up the tool in the center of the work area.
Apart from exterior influences, device specific
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.
First, check both the height as well as the
leveling accuracy of the horizontal laser line,
then the leveling accuracy of the vertical laser
line.
Should the tool exceed the maximum deviation
during one of the tests, please have it repaired
by a Bosch after-sales service center.
Lock Mode - Working without Automatic
Leveling (see figure E)
For work without automatic leveling, press the
"Lock" button 7. When the automatic leveling is
switched off, the indicator 11 lights up red.
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 two laser lines do
not necessarily run at a right angle to each
other.

Working Advice

Always use the center of the laser line for
marking. The width of the laser line changes
with the distance.
