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:
An 8mm Allen wrench is provided for this adjustment. Make tracking adjustments on the left
side bolt. Set the belt speed to 3 mph. Be aware that a small adjustment can make a
dramatic difference which may not be apparent right away. If the belt is too close to the left
side, then turn the bolt only a 1/4 turn to the right (clockwise) 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.
If the belt is too close to the right side, turn the bolt
counter-clockwise. The belt may require periodic
tracking adjustment depending on use and walking/
running characteristics. Some users may 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.
Unplug treadmill before performing any maintenance.
