Maintenance and Service

Maintenance and Cleaning
Before any work on the machine (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion. Unintentional actuation of the On/Off
switch can lead to injuries.
For safe and proper working, always keep
the machine and ventilation slots clean.
When the battery is no longer operative, please
refer to an authorised after-sales service agent
for Bosch power tools.
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.
