4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your treadmill. Always unplug the treadmill before performing any maintenance.
4.1 Lubrication
The running belt requires periodic lubrication to reduce friction and extend its lifespan. A bottle of lubricant is included with your treadmill.
- Frequency: Lubricate the belt every 30-50 hours of use, or every 1-2 months with regular use.
- Procedure:
- Turn off and unplug the treadmill.
- Loosen the rear roller bolts slightly to lift the belt.
- Apply a small amount of the provided silicone lubricant evenly under the center of the running belt.
- Tighten the rear roller bolts.
- Plug in the treadmill and run it at a low speed (e.g., 1 MPH) for 5 minutes to distribute the lubricant.
4.2 Belt Adjustment
If the running belt shifts to one side or feels loose, it may need adjustment. A hex wrench is included in the tool kit.
- Centering the Belt:
- Turn on the treadmill and set the speed to 1-2 MPH.
- If the belt drifts to the right, turn the right rear adjustment bolt clockwise a quarter turn.
- If the belt drifts to the left, turn the left rear adjustment bolt clockwise a quarter turn.
- Allow the treadmill to run for a few minutes and observe. Repeat adjustments as needed until the belt is centered.
- Tightening the Belt: If the belt slips during use, it may be too loose.
- Turn off and unplug the treadmill.
- Turn both the left and right rear adjustment bolts clockwise by a quarter turn.
- Plug in and test the treadmill. Repeat if necessary, but avoid overtightening.
4.3 Cleaning
- Wipe down the treadmill surface with a damp cloth after each use to remove sweat and dust.
