5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your treadmill.
5.1 Cleaning
- Wipe down the treadmill surfaces with a damp cloth after each use to remove sweat and dust.
- Do not use abrasive cleaners or solvents.
5.2 Running Belt Lubrication
Proper lubrication of the running belt is crucial to reduce friction and extend the life of the motor and belt.
- Lubricate the running belt every 3-6 months, or after approximately 50 hours of use, using 100% silicone lubricant.
- Lift the edge of the running belt and apply a thin line of lubricant to the center of the deck underneath the belt.
- Run the treadmill at a low speed (e.g., 3 km/h) for a few minutes to distribute the lubricant evenly.
5.3 Running Belt Adjustment
If the running belt shifts to one side or slips, it may need adjustment.
- Centering: If the belt drifts to one side, use the provided Allen key to turn the adjustment bolt on the corresponding side (clockwise to move the belt to the right, counter-clockwise to move it to the left) in small increments (quarter turns). Run the treadmill for a few minutes after each adjustment until the belt is centered.
- Tensioning: If the belt slips during use, it may be too loose. Turn both rear adjustment bolts clockwise in small, equal increments to increase tension. Do not overtighten.
