when operating your product, only the
following cable dimensions should be
used:

– 1.0 mm2: max. length 40 m
– 1.5 mm2: max. length 60 m

2

– 2.5 mm

: max. length 100 m

Note: If an extension cable is used it
must be earthed and connected
through the plug to the earth cable of
your supply network in accordance
with prescribed safety regulations.

If in doubt contact a qualified electri­cian or the nearest Bosch Service Cen­tre.

 WARNING! Inadequate extension

cables can be dangerous. Exten­sion cable, plug and socket must
be of watertight construction and
intended for outdoor use.

Cable connections should be kept dry
and off the ground.

It is recommended for increased elec­trical safety to use a Residual Current
Device (RCD) with a tripping current of
not more than 30 mA. Always check
your RCD every time you use it.

For products not sold in GB:
WARNING: For your safety, it is re­quired that the plug attached to the ma­chine is connected with the extension
cord. The coupling of the extension
cord must be protected against splash
water, be made of rubber or coated
with rubber. The extension cord must

electric plug with internal fuse (ASTA
approved to BS 1362).
If the plug is not suitable for your socket
outlets, it should be cut off and an ap­propriate plug fitted in its place by an
authorised customer service agent.
The replacement plug should have the
same fuse rating as the original plug.
The severed plug must be disposed of
to avoid a possible shock hazard and
should never be inserted into a mains
socket elsewhere.
Products sold in AUS and NZ only:
Use a residual current device (RCD)
with a rated residual current of 30 mA
or less.
