Maintenance and Cleaning

f

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.

f

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.
