3. Proper Motor Function
• Verify that the treadmill is properly lubricated ( Reference Maintenance Section ) and drive motor is
operating at the proper amperage rating. To verify the current draw, place a clamp meter around the red motor
wire. If a clamp meter is not available, an additional wire harness can be produced to measure amperage
with a standard voltmeter.

• Remove the brush covers on the drive motor and inspect the brushes and the motor commutator
for any uneven wear. If the surface of the motor brush is pitted, rough, has burn marks, or the commutator
has a black residue on it, replace the motor brush and stone the motor commutator. (
Reference Motor Brush
Replacement and Stoning the Commutator in Spare Parts Replacement Section. )
4. Proper Speed Calibration
• To ensure proper belt speed and proper calibration use engineering mode to verify that machine is
running in MPH not KM (all models) and that the correct roller diameter is set (1.T - 5.T only). ( Reference
Engineering Mode Section. )
• Auto-calibrate the machine from engineering mode if the belt speed is erratic or the belt speed does
not correspond to what is displayed on the console. ( Reference Engineering Mode Section.)
5. Voltage Checkpoints/Diagnostic LED’s
• Verify that the motor control board is functioning properly by referencing the Diagnostic LED’s
located on the lower control board. ( Reference Voltage Checks & LED Diagnosis Section.)
• Verify that proper voltage is being transferred through the console cable.
If the techniques described in the five-step diagnostic process did not resolve the problem, reference the
symptoms in the table of contents and review other possible causes in the troubleshooting section.
