Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and the ventilation slots clean.
In extreme working conditions, conductive
dust can accumulate in the interior of the
machine when working with metal. The
protective insulation of the machine can be
be
degraded. The use of a stationary extrac-
tion system is recommended in such cases
as well as frequently blowing out the venti-
lation slots and installing a residual current
device (RCD).
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit order number
given on the nameplate of the machine.

necting a new 3-pin plug to the 2-wire cable.
