5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your treadmill.
Cleaning
- Daily: Wipe down the console and other surfaces with a soft, damp cloth after each use to remove sweat and dust.
- Weekly: Vacuum under the treadmill to prevent dust and debris from accumulating.
- Do not use abrasive cleaners or solvents.
Lubrication
The running belt requires periodic lubrication to reduce friction and extend its lifespan. Use only the provided lubricant or a silicone-based treadmill lubricant.

Image: Diagram illustrating the process of applying lubricating oil to the treadmill belt, showing where to apply it for smooth operation.
- Frequency: Lubricate every 3 months or after 50 hours of use, whichever comes first.
- Procedure: Unplug the treadmill. Lift the edge of the running belt and apply a small amount of lubricant directly onto the center of the deck, under the belt. Repeat on the other side.
- Spread: Plug in the treadmill and walk on it at a low speed (e.g., 1-2 mph) for 5 minutes to evenly distribute the lubricant.
Running Belt Adjustment
If the running belt drifts to one side or slips, it may need adjustment. Use the L-shaped wrench provided.
