TREADBELT TRACKING ADJUSTMENT:
The performance of your treadmill is dependent on the frame running on a reasonably level
surface. If the frame is not level, the front and back roller cannot run parallel, and constant
belt adjustment may be necessary.
The treadmill is designed to keep the tread-belt reasonably centered while in use. It is normal
for some belts to drift near one side while the belt is running with no one on it. After a few
minutes of use, the tread-belt should have a tendency to center itself. If, during use, the belt
continues to move toward one side, adjustments are necessary.
TO SET TREADBELT TRACKING:
A 6 mm Allen wrench is provided to adjust the rear roller. Make tracking adjustments from the
left side only. Set belt speed at
approximately 2 to 3 mph. A small
adjustment can make a dramatic
difference. Turn the bolt only a 1/4 turn
and wait a few minutes for the belt to
adjust itself. Continue to make 1/4
rotation turns until the belt stabilizes in
the center of the running deck. The belt
may require periodic tracking adjustment
depending on use and walking/running
characteristics. Some users will affect
tracking differently. Expect to make adjustments as required to center the tread-belt.
Adjustments will become less of a maintenance concern as the belt is used. Proper belt
tracking is an owner responsibility common with all treadmills.
ATTENTION:
DAMAGE TO THE RUNNING BELT RESULTING FROM IMPROPER TRACKING /
TENSION ADJUSTMENTS IS NOT COVERED UNDER THE SPIRIT WARRANTY.
