Initial Operation
An accuracy check should always be
carried out before use.
Protect the tool against
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.
Leveling Accuracy
Set up the tool on the floor surface to
be checked, ensuring that it is firmly
positioned.
The leveling accuracy can be influenced
through the ambient temperature.
Especially temperature differences
occurring from the ground upward can
deflect the laser beam. As the thermal
layering is greatest at ground level, the
tool should always be set up in the center
of the floor surface to be checked.
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.
Should the tool exceed the maximum
deviation during one of the tests, please
have it repaired by a Bosch after-sales
service.
Switching On and Off
To switch on the tool, slide the On/Off
switch 8 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.
Do not leave the switched on tool
unattended and switch the tool off
after use.
To switch off the tool, slide the On/Off
switch 8 to the “Off” position. When
switching off, the leveling unit is locked.
When the tool is not moved or remote-
controlled for approx. 30 minutes, it
switches off automatically to save the
batteries or the battery pack.
After switching off automatically, switch
the tool off via On/Off switch 8 and then
on again, if required.
When exceeding the maximum permitted
operating temperature of 50º C, the tool
switches off to protect the laser diode.
After cooling down, the tool is ready for
operation and can be switched on again.
Operation with Optional Rechargeable
Battery Pack
The “Electronic Cell Protection (ECP)”
protects the lithium ion battery pack
against deep discharging. When the
battery pack is discharged, the tool is
switched off by a protective circuit.
When the tool switches
off automatically due to a
discharged battery pack, switch the tool
off with the On/Off switch 8. Charge the
battery pack before switching the tool
on again. Otherwise, the battery pack
could become damaged.
