Maintenance and Service

Maintenance and Cleaning

Note: The measuring tool can also be calibrated via
the "CAL" (calibration) menu. This calibration may
only be carried out through an authorised service
agent for Bosch power tools.
Store and transport the measuring tool only in the sup-
plied case.
Keep the measuring tool clean at all times.
Wipe off debris using a moist and soft cloth. Do not
use any cleaning agents or solvents.
Regularly clean the surfaces at the exit opening of the
laser in particular, and pay attention to any fluff of
fibres.
When heavily contaminated, the measuring tool can
be cleaned under running water. Do not immerse the
measuring tool in water and do not subject it to a high-
pressure water jet.
Note: Before storing, allow the measuring tool and the
case to dry completely. Otherwise, vapours can devel-
ope in the closed case due to residual moisture, lead-
ing to corrosion of the measuring tool's circuit board. In
this case, warranty claims shall be rendered void.
If the measuring tool should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an authorised after-sales
service centre for Bosch power tools. Do not open the
measuring tool yourself.
In all correspondence and spare parts orders, please
always include the 10-digit article number given on
the type plate of the measuring tool.
