THE SYSTEM ELECTRICALLY BY SWITCHING OFF THE INCOMING MAINS
SAFETY ISOLATOR (MOUNTED ADJACENT TO THE MACHINE) .

What may appear to be faults are sometimes simply the failure on the part of the operator to
follow the correct procedures. Before spending time, therefore, searching for a failed
component, ensure that the pre-power-up check has been carried out (see Section 5) and that
all plugs and connectors are secure.
