The discontinued Proform 520X treadmill may be gone but not forgotten. You can still find used ones for sale and some parts, such as the console, can still be purchased online, though you'll likely need a technician to install one for you. Basic troubleshooting without the need of a professional can be performed on your own using just the tool that comes with your Proform.

520X Power Goes Off During Use

Locate the on/off circuit breaker. This is a switch positioned sideways near the power cord. Press the switch back in if it has tripped and the right side is sticking out.

Unplug the treadmill from the wall. Wait 5 minutes and then plug the treadmill back in.

Take the key clip out the slot in the console. Reinsert the key. Turn on the treadmill. Call Proform customer service if you still cannot get the treadmill to come back on.

520X Treadmill Will Not Power On

Check that the power cord is plugged into the appropriate single-outlet surge suppressor. The Proform 520X treadmill must have a voltage rating of 400 volts or fewer and a minimum surge dissipation of 450 joules. Check that the rating is for at least 120 volts AC and 15 amps. The Proform 520X is incompatible with GFCI-equipped outlets. Speak with an electrician about your outlet if it is not GFCI-equipped.

Put the key into the console and push it in firmly.

Find the on/off circuit breaker. Flip the switch to the "reset" position after 5 minutes time if the breaker has tripped.

520X Walking Belt Troubleshooting

Remove the safety key from the console. Unplug the treadmill.

Use the allen wrench supplied by Proform to adjust the rear roller bolt on the side that is off center. If the right side of the belt has moved too far to the right, turn the right bolt a half-turn clockwise. Do the opposite if the treadmill is too far to the left. Continue until the belt is centered.

Check that the rear adjustment bolts are not too tight. Bolts that are too tight will cause the belt to slow down during exercise. Bolts that are too loose will cause the treadmill belt to slip. Attempt to lift each side of the belt toward the ceiling. Loosen one or both sides if the belt will not rise at least 2 inches. Do this by making one-quarter turns at a time on the rear adjustment bolt using the allen wrench. Turn the bolts counterclockwise to loosen them. Tighten the bolts if you lift the belt more than 3 inches by making one-quarter turns clockwise.

520X Incline Troubleshooting

Insert the safety key with the treadmill plugged in. Turn the machine and start walking.

Press the incline button to raise the incline. Take the key out as the treadmill is rising.

Wait a few seconds and then put the key back into the console. Let the treadmill automatically lift to the highest incline level and then lower back down to no incline, as this will calibrate the incline.

Tips

Follow the directions for "Incline Troubleshooting" if the incline does not change in sync with iFit.com videos and CDs.
