Maintenance
Regular maintenance ensures the longevity and optimal performance of your treadmill. Always unplug the treadmill before performing any maintenance.
1. Cleaning
- Wipe down the treadmill's surfaces with a damp cloth after each use to remove sweat and dust.
- Do not use abrasive cleaners or solvents, as these can damage the finish.
- Keep the area around the treadmill clean and free of debris.
2. Belt Lubrication
The running belt requires periodic lubrication to reduce friction and extend its lifespan. A small bottle of lubrication oil is included with your treadmill.
- Turn off and unplug the treadmill.
- Loosen the rear roller bolts slightly to lift the running belt.
- Apply a small amount of silicone lubricant (provided) evenly under the center of the running belt.
- Tighten the roller bolts.
- Plug in the treadmill and run it at a low speed (e.g., 3 KM/H) for 5 minutes to distribute the lubricant.
- Lubricate the belt every 3-6 months, depending on usage.
3. Belt Tension and Alignment
- If the running belt feels loose or slips during use, it may need tensioning. Refer to the detailed instructions in the full manual (if available) or contact customer support.
- If the running belt drifts to one side, it needs alignment. Adjust the rear roller bolts incrementally (e.g., quarter turns) until the belt is centered.
