Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales serv-
ice.
Service Indicator 6 (GBH 4 DSC)
When the carbon brushes are worn out, the ma-
chine switches itself off. This is indicated ap-
prox. 8 hours beforehand by the lighting or
blinking of the service indicator 6. The machine
must then be sent to an after-sales service
agent. Addresses are listed in the Section "Af-
ter-sales service and customer assistance".
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 order,
please always include the 10-digit article
number given on the type plate of the machine.
