Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
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.
WARNING! Important instructions for con-
necting a new 3-pin plug to the 2-wire cable.
The wires in the cable are coloured according to
the following code:
Do not connect the blue or brown wire to the
earth terminal of the plug.
Bosch Power Tools
Important: If for any reason the moulded plug is
removed from the cable of this power tool, it
must be disposed of safely.
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. There-
fore, always keep the area around the retracting
blade guard clean.
Remove dust and chips after each working pro-
cedure by blowing out with compressed air or
with a brush.
Clean the roller 7 and the lighting and laser unit
(45, 46) regularly.

Replacing the Carbon Brushes

(see figure X)
Check the length of the carbon brushes approx.
every 2 – 3 months and replace the carbon
brushes if required.
Never replace only a single carbon brush!
Criteria for replacement of the carbon brushes:
A dotted or broken line is visible on one of the
large side surfaces of each carbon brush. When
either of both carbon brushes is used up to this
line, then both carbon brushes should be re-
placed immediately in order to protect the ar-
mature against possible damage.
Note: Use only carbon brushes supplied by
Bosch and intended specifically for your prod-
uct.
– Unscrew the caps 60 using a suitable screw-
driver.
– Replace the spring-loaded carbon brushes
61 and screw the caps back on again.
