Safety informa on
WARNING!
Danger of electrocu on!
Improper use, incorrect electrical installa on or a voltage that is too
high can all lead to electrocu on.
– Connect the grinder only if the mains voltage of the socket com-
plies with the informa on indicated on the nameplate.

power cable or plug is faulty.
– If the power cable for the grinder is damaged, it must be replaced
by the manufacturer or by qualifi ed personnel in order to avoid
hazards.
– Connect the grinder only to a power supply with a 16 A-slow
back-up fuse. Have the 16 A-slow back-up fuse fi  ed by a quali-
fi ed electrician if the power connec on at the site of installa on
of the grinder is not secured in this way.

grinder when the motor becomes too hot. As soon as the motor
has cooled down, the grinder can be put into opera on again
(see chapter: “Troubleshoo ng”).
Connec ng the grinder and se ng the grinding degree
