Elevation Troubleshooting
** CAUTION **
Do not stand on
the running belt
while perform-
ing these steps.
NOTE:These ran-
ges were chosen
to optimize the
output voltage to
the elevation
motor within an
acceptable
operating range,
while still using

tolerances of the

220v treadmill Incline Range Adjustment for Free-wheeling symptom.
Symptom:
Treadmill free-wheels at high elevation, causing the running
belt to slowly accelerates beyond the selected speed.
1. This symptom may be easily fixed by changing certain values in the Configure
Mode. Engage Manager/Maintenance Mode by holding down the “0”, “1” and
“Start” keys at the same time, and then release the “1” key only.
2. Press the elevation “↑” key until the display window reads “EL MAX 57”.
Change the “57” to “80” by pressing the “+” key.
3. Press the “START” key and the display window will show “UPDATING”. This
will save the “80” in the parameter.
4. Press the “STOP” key to exit the Manager or Maintenance Mode. Procedure
completed.
Symptom:
Elevation Motor overheats and blows the MCB fuse.
1. The elevation motor on the 4500 series treadmill uses 115 VAC. On 230 volt
treadmills, there is an autotransformer which will lower the voltage to operate
the elevation system.
2. Line voltage may vary from location to location. Some locations have line
voltages as low as 195 VAC or as high as 250 VAC. The autotransformer has
been manufactured with two taps to accommodate these variations in voltage.
The two taps are:
• 190 to 210 VAC line voltage
• 210 to 250 VAC line voltage
