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 8.
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 when walked on, please call our Customer Service Department.
