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 treadbelt 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 treadbelt 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 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 treadbelt. 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.
