Maintenance
Belt Tension Adjustment

Follow the instructions provided in the assembly manual for proper belt tension adjustment. Incorrect adjustment can affect performance and belt longevity.
Lubrication
Regular lubrication of the walking belt is crucial for maintaining smooth operation and extending the life of your treadmill. Apply spray lubricant under the belt as advised in the assembly manual or as needed based on usage. Ensure the treadmill is off and stable before applying lubricant.
Cleaning
Wipe down the treadmill frame and monitor with a damp cloth after each use to remove sweat and dust. Avoid using abrasive cleaners or solvents that could damage the finish or electronic components. Keep the walking surface clean and free of debris.
