Belt care

Most belt problems are slipping, drifting to one side, or noise. All have simple first fixes. Unplug the treadmill before touching anything but the bolts.

Drifting to one side#

Adjust the rear roller bolts a quarter turn at a time, with the belt running slowly and nobody on it. Follow your manual.

Slipping#

Usually too loose: tighten both rear bolts equally, a quarter turn at a time. Don't overtighten.

Lubrication#

Many belts need silicone lube every few months or by hours of use. Check the manual: some are maintenance-free.

Call for service#

Burning smells, a frayed belt, grinding noises, or a motor that labours under you.

Should I talk to my doctor before walking?

If you have a heart, lung or other health condition, take medicines that affect heart rate or blood sugar, or haven't been active for a long time, yes. Our printable question list helps.

Is it OK to walk if it hurts?

Mild soreness is common when starting. Sharp, worsening or chest pain means stop and get checked.

How hard should I walk?

Use the talk test: you should be able to talk in full sentences.
