Bosch GCL 2-15 G Professional Originalbetriebsanleitung Seite 19

Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the
same capacity.
Take the batteries out of the measuring tool when you
u
are not using it for a prolonged period of time. The bat-
teries can corrode and self-discharge during prolonged
storage in the measuring tool.
Working with the RM 1 rotating mount
(see figures A1–A3)
You can use the rotating mount (14) to rotate the measuring
tool 360° around a central, always visible plumb point. This
enables you to set up the laser lines without having to
change the position of the measuring tool.
Place the measuring tool with the guide groove (8) on the
guide rail (15) of the rotating mount (14) and slide the
measuring tool all the way onto the platform.
To disconnect the measuring tool, pull it off the rotating
mount in the opposite direction.
Rotating mount positioning options:
– Standing on a flat surface,
– Screwed to a vertical surface,
– On metallic ceiling strips using the ceiling clip (18),
– On metallic surfaces using the magnets (17).
Keep your fingers away from the rear side of the mag-
u
netic accessory while attaching the accessory to sur-
faces. The strong pulling force of the magnets may jam
your fingers.
Operation
Starting Operation
Protect the measuring tool from moisture and direct
u
sunlight.
Do not expose the measuring tool to any extreme tem-
u
peratures or variations in temperature. For example,
do not leave it in a car for extended periods of time. In
case of large variations in temperature, allow the measur-
ing tool to adjust to the ambient temperature before put-
ting it into operation. The precision of the measuring tool
may be compromised if exposed to extreme temperat-
ures or variations in temperature.
Avoid substantial knocks to the measuring tool and
u
avoid dropping it. Always carry out an accuracy check
before continuing work if the measuring tool has been
subjected to severe external influences (see "Accuracy
Check of the Measuring Tool", page 21).
Switch the measuring tool off when transporting it.
u
The pendulum unit is locked when the tool is switched off,
as it can otherwise be damaged by big movements.
Switching On/Off
To switch on the measuring tool, slide the on/off switch (9)
to the On position (for working with the pendulum lock) or
to the On position (for working with automatic levelling).
Bosch Power Tools
As soon as it is switched on, the measuring tool emits laser
beams from the outlet apertures (1).
Do not direct the laser beam at persons or animals and
u
do not stare into the laser beam yourself (even from a
distance).
To switch off the measuring tool, slide the on/off switch (9)
to the Off position. The pendulum unit is locked when the
tool is switched off.
Never leave the measuring tool unattended when
u
switched on, and ensure the measuring tool is
switched off after use. Others may be blinded by the
laser beam.
If the maximum permitted operating temperature of 50 °C is
exceeded, the tool shuts down to protect the laser diode.
Once it has cooled down, the measuring tool is operational
again and can be switched back on.
Automatic Shut-Off
If no button on the measuring tool is pressed for approx.
120 min, the measuring tool will automatically switch itself
off to preserve battery life.
To switch the measuring tool back on after it has been auto-
matically switched off, you can either slide the on/off
switch (9) to the "Off" position first and then switch the
measuring tool back on, or press either the laser point mode
button (4) or the laser line mode button (5).
Temporarily Deactivating Automatic Shut-Off
To deactivate the automatic shut-off function, hold down the
laser line mode button (5) for at least 3 s (with the measur-
ing tool switched on). If the automatic shut-off function is
deactivated, the laser beams will flash briefly as confirma-
tion.
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 meas-
uring tool off and on again.
Setting the Operating Mode
The measuring tool has several operating modes, which you
can switch between at any time:
– Cross-line and point mode: The measuring tool gener-
ates a horizontal and a vertical laser line as well as two
vertical laser points, one facing up, the other down. The
laser lines cross at a 90° angle.
– Horizontal line mode: The measuring tool generates a
horizontal laser line in front of it.
– Vertical line mode: The measuring tool generates a ver-
tical laser line in front of it.
Positioning the measuring tool in the room displays the
vertical laser line on the ceiling beyond the top laser
point.
If the measuring tool is positioned directly against a wall,
the vertical laser line almost encircles the entire space
(360° line).
– Point mode: The measuring tool generates two vertical
laser points, one facing up, the other down.
