f Never use the machine with a damaged ca-
ble. Do not touch the damaged cable and
pull the mains plug when the cable is dam-
aged while working. Damaged cables in-
crease the risk of an electric shock.
Products sold in GB only: Your product is fitted
with an BS 1363/A approved 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 fit-
ted in its place by an authorised customer serv-
ice 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 in-
serted into a mains socket elsewhere.

ual current device (RCD) with a rated residual
current of 30 mA or less.
