Belt Tension And Aligning The Running Belt - LifeSpan TR8000i Owner's Manual

Belt Tensioning
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 (5 KPH). 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.
Aligning the Running Belt
Ensure the running belt is centered on your treadmill at all times. Running style and a non-level surface are
two instances that may cause the belt to drift off center. Minor adjustments to the two bolts at the rear of the
treadmill are necessary when the belt has drifted off the center.
1. Press START, then increase the treadmill speed to 3 MPH (5 KPH).
2. Stand at the rear of the treadmill to determine which direction the belt is drifting.
3. If the belt drifts to the left, turn the left adjustment bolt one-quarter turn clockwise and the right
adjustment bolt one-quarter turn counter-clockwise. (See FIG. 1)
4. If the belt drifts to the right, turn the left adjustment bolt one-quarter turn counter-clockwise and the
right adjustment bolt one-quarter turn clockwise. (See FIG. 2)
5. Observe the tracking of the belt for about two minutes. Repeat steps 3, 4 and 5 as needed.
