Adjusting the Tension
qqqqq
WARNING SECURE LONG HAIR AND LOOSE CLOTHING BEFORE
WORKING NEAR THE TREADMILL WALKING SURFACE OR PULLEYS.
As the treadmill’s walking belt stretches through use it will become necessary
to adjust tension on the belt. This often occurs within the first few months
of use. Adjust the belt tension whenever the belt slips or moves unsteadily
during operation.
The belt tension is adjusted by moving the rear roller of the treadmill back to
reduce slack. This is accomplished by turning the adjustment bolts located on
the back of the treadmill.

IMPORTANT Do not over tighten walking belt! The belt need only
be tight enough to prevent it from slipping during use. Excessive belt tension will
decrease belt life and can damage the treadmill rollers and drive system.
1. Using a ½ inch socket, turn the left and right adjusting bolts clockwise ½ turn.
Use care to make each adjustment equal to ensure proper belt alignment.
2. Test the belt by running on the belt at about 4 MPH. Hold the handrail lightly
and resist the belt movement with your feet. If walking belt slips, repeat step 1.
