Maintenance and Service

Maintenance and Cleaning
Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
The retracting blade guard must always be able to move
freely and retract automatically. It is therefore important to
keep the area around the retracting blade guard clean at all
times.
Always remove dust and chips after working by blowing out
with compressed air or using a brush.
Clean the guide roller (17) regularly.
