LifeSpan TR4000I manual Belt Tensioning, Aligning the Running Belt

TR3000i / TR4000i

Belt Tensioning Folding Treadmill

If the belt begins to slip during use, it will need to be tensioned. Your treadmill is equipped with tension bolts that are accessible from the back of the treadmill. Before tensioning the belt, start the treadmill and set the speed to 3 MPH. Using a 6 mm Allen Wrench, included in your hardware bag, turn the right and left tension bolts 1/2 turn clockwise.

After you adjust each side 1/2 turn, test to see if the slipping is eliminated. If the belt slips repeat this step and test again.

If you turn one side more than the other, the belt will start to drift to the side of the treadmill and will need to be aligned. DO NOT tighten more than 2 full turns on each side. If slippage still occurs, contact LifeSpan Customer Service.

Note: Over tensioning the belt can cause unnecessary friction and wear and tear on the belt, motor and electronics.
