5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your WalkingPad X218 treadmill.
Lubrication
The treadmill belt requires lubrication every 30 to 60 hours of operation to reduce friction and wear. Use 100% silicone treadmill oil.
- Turn off and unplug the treadmill.
- Lift one side of the running belt.
- Apply 5-10 ml of silicone oil (2-3 presses of the applicator) in a wave pattern on the running deck, about 10-15 cm from the edge of the belt and 40 cm from the motor cover.
- Repeat the process on the other side of the belt.
- Plug in the treadmill and walk on it for 3 minutes at a low speed (e.g., 3 km/h) to spread the lubricant evenly.
