4.1 Disassembly warnings
The mains cable must
be disconnected from the power supply when disassembling or repairing the
machine.
The loom harness and terminals used must be for the correct wire size and the correct tools must be
used to crimp any terminals onto the harness. Insulation tape must be used where appropriate.
When attaching terminals to the mating connectors, always ensure that they are pushed fully on.
When attaching a wire via a screw terminal, ensure that sufficient wire is underneath the screw
terminal. Ensure that the screw is tightened satisfactorily.
The loom harness should not touch any moving parts or sharp edges. The wiring route around high
temperature objects (e.g. motor) should be followed as per the initial construction.
Always use the specified screws
