PROBLEM: The walking belt slows when walked on
SOLUTION: a. Use only a single-outlet surge suppressor that meets all of the specifications described on page 9.
b. If the walking belt is overtightened, treadmill perfor-
mance may decrease and the walking belt may be-
come damaged. Remove the key and UNPLUG THE
POWER CORD. Using the allen wrench, turn both
rear roller adjustment bolts counterclockwise, 1/4 of a
turn. When the walking belt is properly tightened, you
should be able to lift each side of the walking belt 3 to
4 inches off the walking platform. Be careful to keep
the walking belt centered. Plug in the power cord, in-
sert the key and run the treadmill for a few minutes.
Repeat until the walking belt is properly tightened.
c. If the walking belt still slows, please call our Customer Service Department, toll-free.

rear roller bolt clockwise 1/2 of a turn; if the walking
belt has shifted to the right, turn the bolt counterclock-
wise 1/2 of a turn. Be careful not to overtighten the walk-
ing belt. Plug in the power cord, insert the key and run
the treadmill for a few minutes. Repeat until the walking
belt is centered.
b. If the walking belt slips when walked on, first remove the

key and carefully walk on the treadmill for a few min-
utes. Repeat until the walking belt is properly tightened.
