Closing the switch begins the cycle.
• Turn the power to the machine off.
• Turn the Foot Pedal and guard over and remove the two small screws that hold the pedal to
the base.
• Use a flat tip screwdriver to pry the pedal free from the yellow guard (it is held by a silicone
caulk).
• Using a flat or Phillips screw driver, remove the two screws on the left and right side of the
pedal. This will allow the pedal to come apart exposing the switch underneath.
• Use two leads of the ohmmeter to probe the wire terminals while the switch is still in the
pedal. (Fig 25)
