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 by
blowing out with compressed air or with a
brush.
Saw blades that are not coated can be protect-
ed against corrosion with a thin coat of acid-free
oil. Before use, the oil must be removed again,
otherwise the wood will become soiled.
Resin and glue residue on the saw blade produc-
es poor cuts. Therefore, clean the saw blade im-
mediately after use.
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.
Important: If for any reason the moulded plug is
removed from the cable of this power tool, it
must be disposed of safely.
Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
