To extend the lifespan of your treadmill, you should lubricate it every 200 km of use. Please use Domyos lubricant only (Ref: 8326425). You can order it from your Decathlon store or online from our website 1 & 2. Simply spray twice underneath the running belt on the right and on the left.3. Then set your treadmill off at 5 km/h for 5 minutes, without standing on it.
