Treadmills Frequently Asked Questions

Treadmill Troubleshooting

1. The console only reads zeros.

If the console takes batteries, replace them. If this does not work or your console does not require batteries, check the reed switch or optic sensor.

Reed Switch: Unplug the treadmill and remove the motor hood cover. The reed switch is mounted on the frame next to the front roller pulley. There is a magnet glued into the front roller pulley. When adjusting the reed switch, make sure it is pointing directly at the magnet. Move the tip of the reed switch within 1/8" of the magnet. Also, check to see that the wire is not damaged, and is connected to the console.

Optic Sensor: Unplug the treadmill and remove the motor hood cover. The optic disk and sensor are located either at the end of the motor or the right hand side of the front roller. The optic disk spins between two sensors on the optic switch. The disk must spin freely without touching either sensor. The sensors can be moved by loosening the adjustment bolt holding the switch to its bracket. The switch can then be slid. Center the disk.

2. The belt stops when I'm walking on the treadmill.

If the belt starts again when you step off, check the tension between the walking belt and board. The belt should lift 3-4". If the tension is fine, let the machine run by itself for a few minutes longer than your last workout or the last time the belt stopped. If the belt maintains its speed, the walking belt may be worn or lacking lubrication. Check your owner's manual or call the customer service hotline to find the lubrication appropriate for your machine. If the belt does not maintain its speed, call the customer service hotline.

3. How can I adjust the walking belt?

Play this video Treadmills have two different styles of walking belt adjustment. To see which type you have, look at the right hand side of the rear roller. If the bolt has an Allen wrench head, you have the two-adjustment bolt style. If the bolt is a hex head, you have the one-adjustment bolt style.

Two-adjustment bolt:

If the walking belt has shifted to the left, first remove the safety key and unplug the power cord. Using the Allen wrench, turn the left rear roller adjustment bolt clockwise, and the right bolt counter-clockwise, 1/4 of a turn each. Be careful not to over tighten the walking belt. Plug in the power cord, insert the safety key and run the treadmill for a few minutes. Repeat until the belt is centered.

6. There is no reading from chest pulse monitor.

  • Make sure the heart rate monitor is under your clothing, against your skin, and as high under the pectoral muscles as is comfortable.
    Note: If the heart rate monitor does not function when positioned as described, try moving it slightly lower or higher on your chest.
  • Make sure the logo on the sensor is facing forward and is right side up.
  • Use saline solution (saliva or contact lens solution) to wet the two electrode areas on the sensor unit. If the heart rate readings do not appear until you begin perspiring, re-wet the electrode areas.
  • As you walk or run on the treadmill, position yourself near the center of the walking belt. For the console to display heart rate readings
  • The heart rate monitor is designed to work with people who have normal heart rhythms. Heart rate detection problems may be caused by medical conditions such as premature ventricular contractions (pvcs), tachycardia bursts, and arrhythmia.
  • The operation of the heart rate monitor can be affected by magnetic interference caused by high power lines or other sources. If you suspect that magnetic interference may be causing a problem, try relocating the treadmill.
  • If the heart rate monitor still does not function properly, test it by having another person try it.

7. There is no reading from hand grip pulse bar.

Hand Grip Pulse Sensor / EKG:

  • Clean the metal contacts with a damp cloth.
  • Make sure the palm of your hand is wrapping around both the top and bottom plates of the pulse sensor. Just the thumb wrapping around the bottom is not sufficient.
  • Before taking your pulse, stop walking and step onto the side rails. Holding still will bring the best pulse reading.
  • If no pulse at all appears on the console for a great length of time, the console software may be locked up and need to be reset. To reset the console:
  • Stop the machine and unplug from the wall, leaving the safety key in.
  • Wait at least 30 seconds.
  • Plug the power cord back in, PO should appear on the console.
  • Remove the safety key momentarily to clear the PO, then reinsert the key.
  • Check the function of the hand pulse. If the pulse is still not registering, repeat this procedure.

8. Console Demo Mode

When in Demo Mode, the console will go through a repeating lighting pattern. This mode will only become active when the treadmill is plugged in, the main on/off switch is turned on, and the safety key is not inserted into the console.

The Demo Mode was added to attract attention to the treadmill while it is on display. By default, all treadmills with Demo Mode will come with it turned on. Demo Mode can be turned off at any time.

9. Is there maintenance for my treadmill?

If your machine has a maintenance free belt, there are only a couple of things that we recommend. First, routinely check the tension on your walking belt. We recommend that you be able to lift your belt 3-4 inches from the platform at the outer edges. Second, we also suggest checking the nuts and bolts to make sure that everything stays tight.

10. What is this white powder coming from my treadmill?

Your treadmill features a maintenance-free walking belt coated with Performant Lube, a high-performance lubricant.

During the first few hours of use, it is normal for a small amount of white powder to appear on the foot rails, walking platform and possibly the floor. The white powder is high-performance lubricant from the walking belt.

Do not apply silicone spray or other substances to the belt or walking platform.
