PROBLEM: The walking belt slows when walked on

SOLUTION: a. Use only a UL-listed surge suppressor, rated at 15 amps, with a 14-gauge cord of five feet or less

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.
