remove any metal dust using compressed air.
8.2 HOW TO PROCEED AFTER MAKING REPAIRS.
After making repairs, always ensure the wires are fully
insulated between the primary side and the secondary
side of the machine. Avoid the wires coming into contact
with moving parts or parts that heat up during operation.
Fit all the clamps back as on the original machine so as to
avoid any contact between the primary and secondary in
case of accidental lead breakage or disconnection.
Also fit the screws back on with the toothed washers as
on the original machine.
