   1. Ensure treadmill power is a dedicated circuit. Verify by turning the breaker at the panel OFF. Using a voltmeter, check for voltage at the treadmill's outlet. With the breaker at the panel OFF, zero volts should be detected from the outlet treadmill connects. If voltage is present, the treadmill is not on a dedicated circuit. Call an electrician to rectify.
5. Advise user of unit's weight limit of 300lbs (137kg).
6. Perform the lift test procedure by pressing 9, 1, 9, ENTER, and then pressing the HILL program key. Inspect the home switch for smooth operation and inspect the wiring of the home switch for damage or poor connections. Inspect the lift motor cable connections and for the presence of the suppressor board (should only be 1).
7. Test the circuit breakers and replace them if necessary.
8. Inspect the lift motor for excessive wear or damage. Replace the lift motor if necessary.
