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.
