Electrical Safety
Your machine is double insulated for safety and re-
quires no earth connection. The operating voltage is
230 V AC, 50 Hz (for non-EU countries 220 V,
240 V as applicable). Only use approved extension
cables. Extension cords/leads should only be used
if they comply with H07-F types or IEC (60227
IEC 53).
If you want to use an extension cable when operat-
ing your product, only the following cable dimen-
sions should be used:
2
– 1.0 mm
: max length 40 m
2
– 1.5 mm
: max length 60 m
2
– 2.5 mm
: max length 100 m
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.
The couplings of connection leads must be pro-
tected against splashes and the coupling sockets on
the leads must be made of rubber or coated with
rubber.
Fixing means for the connection leads must be
used.
The connection lead must be inspected for signs of
damage at regular intervals and may only be used if
in perfect condition.
If the supply cord is damaged, it must be replaced by
a Bosch Service Centre.
