Maintenance and Service
Maintenance and Cleaning
f Before any work on the machine itself, pull the mains
plug.
If the machine should fail despite the care taken in manufac-
turing 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 in-
clude the 10-digit article number given on the type plate of
the machine.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
Cleaning
For safe and proper working, always keep the power tool and
its ventilation slots clean.
The retracting blade guard must always be able to move freely
and retract automatically. Therefore, always keep the area
around the retracting blade guard clean.
Remove dust and chips after each working procedure by
blowing out with compressed air or with a brush.
Clean the roller 38 regularly.
