Maintenance

General Cleaning

Wipe down the treadmill surfaces with a damp cloth after each use. Avoid using abrasive cleaners.

Belt Lubrication

Regular lubrication of the running belt is crucial for optimal performance and longevity. Use the provided silicone treadmill lubricant.

  1. Turn off and unplug the treadmill.
  2. Loosen the rear roller bolts slightly to lift the belt.
  3. Apply a small amount of silicone lubricant evenly under the center of the running belt.
  4. Tighten the rear roller bolts.
  5. Plug in the treadmill and run it at a low speed (e.g., 1 MPH) for 5 minutes to distribute the lubricant.

Frequency: Lubricate every 3 months or after 50 hours of use, whichever comes first.

Belt Adjustment

If the running belt shifts to one side or slips, it may need adjustment.

  • Belt Centering: If the belt drifts to the left, turn the left rear roller bolt clockwise in small increments. If it drifts to the right, turn the right rear roller bolt clockwise. Run the treadmill for a few minutes after each adjustment to check centering.
  • Belt Tension: If the belt slips during use, tighten both rear roller bolts equally in small increments (e.g., quarter turns) until slipping stops. Do not overtighten.
