Treadmill care

A few minutes a month keeps a treadmill quiet, safe and working for years. Always follow your manual first.

Every week#

Wipe the handrails, console and belt edges.
Vacuum under and around the treadmill; dust gets into the motor.
Check the power cord isn't pinched or frayed.

Every month or so#

Check the belt is centered. If it drifts, most manuals say to turn the rear roller bolt a quarter turn at a time with the belt running slowly.
Check tension: the belt should lift a few inches at the middle, and shouldn't slip when you push off.
Lubricate the deck if your manual calls for it, using the lubricant it specifies (often silicone).

Common noises#

Squeaking often means the deck needs lubricating or a bolt needs tightening. Thumping can be a worn belt seam or a roller. Grinding or burning smells mean stop and call a technician.

Safety first#

Unplug before cleaning or adjusting anything other than belt tracking, keep children and pets away, and always clip on the safety key.
