Once a week clean the side rails and any part of the walking/running surface or deck that is visible using a damp cloth. Dirt and dust love to cling to your treadmill deck and walking belt.
Make sure to run your treadmill once every month without anyone on it. Ensure that the running belt is centrally aligned. If not, it should be adjusted. (Refer to your owners manual for belt alignment/adjustment instructions).
Once every month run the treadmill at full speed to clean out any dust or dirt that has gathered. Ensure that there is sufficient amount of lubrication present under the walking belt and on the deck once every month.
Every six months remove the motor hood and vacuum the motor area. Dirt and dust can accumulate on the motor's and electronic components which can be a cause for short circuit. Be careful and alert to switch off the main while doing this procedure.

Using a damp cloth wipe down the ramps once every week. Thoroughly examine the wheels to ensure that no foreign objects are placed in them. Check all the bolts are tight and check your machine is in level.
Verify all pulleys to ensure the cables are fixed properly on them. Check all cables to make sure the coating is present and that none of them is unravelled. If you find one, replace it immediately.
