Tension And Centering The Running Belt - Horizon Fitness T101S Service Manual

CHAPTER 2: Preventative Maintenance
2.2 TENSIONING & CENTERING THE RUNNING BELT
If you can feel a slipping sensation when running on the treadmill, the running belt must be tightened. In most cases, the
belt has stretched from use, causing the belt to slip. This is a normal and common adjustment. To eliminate this slipping,
turn the treadmill off and tension both the rear roller bolts using the supplied Allen wrench, turning them ¼ turn to the right
as shown. Turn the treadmill on and check for slipping. Repeat if necessary, but never turn the roller bolts more than ¼
turn at a time. Belt is properly tensioned when the slipping sensation is gone.
The running belt has been properly adjusted at the factory before it was shipped. At times the belt can move off-center
during shipment. Before operating the treadmill, make sure the belt is centered and remains centered to maintain smooth
operation.
If the running belt is too far to the right side: With the treadmill
running at 1 mph, turn the left adjustment bolt counter-clockwise
¼ turn at a time (using the supplied Allen wrench). Check the belt
alignment. Allow belt to run a full cycle to gauge if more
adjustment is needed. Repeat if necessary, until the belt remains
centered during use.
