TREADBELT TRACKING ADJUSTMENT
The treadmill is designed so that the tread-belt remains reasonably centered while in
use. It is normal for some belts to drift near one side while in use, depending on a
user's gait and if they favor one leg. But if during use the belt continues to move
toward one side, adjustments are necessary.
SETTING TREAD-BELT TRACKING
A 6 mm Allen wrench is provided for this
adjustment. Make tracking adjustments
on the left side bolt. Set belt speed at
3 mph ( 5 kph). 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 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 WARRANTY.
