How to lubricate the treadmill?

WD-40 Multi-Use Product or WD-40 Specialist Silicone Lubricant can be used. Start by unplugging the machine so that it is completely turned off. Clean the belt and loosen it according to the manual. Once the belt can be lifted, spray the aerosol lubricant underneath the belt on both sides, then tighten it again. Plug in the machine and operate it at a low speed. This way, the lubricant will spread across the entire belt. Reapply the lubricant when you notice that the belt slows down.
