How do I lubricate the running deck of my treadmill?

To lubricate your treadmill's running deck, first turn off and unplug the treadmill from the wall outlet, loosen both rear roller bolts, apply lubricant to the entire top surface of the running deck, tighten the bolts back to their original position, plug in the treadmill, insert the safety key, start it, and walk on the belt for two minutes to spread the lubricant. Ensure this maintenance is done every six months or 150 miles. (Page 23)
