PROBLEM: The walking belt slows when walked on

SOLUTION:

a. If an extension cord is needed, use only a 3-conductor, 1mm

2

(14-gauge) cord that is no longer

than 5 ft. (1.5 m).

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 hex key, turn both rear

roller bolts counterclockwise, 1/4 of a turn. When the
walking belt is properly tightened, you should be able
to lift each edge of the walking belt 2 to 3 in. (5 to 8
cm) off the walking platform. Be careful to keep the
walking belt centered. Then, plug in the power cord,
insert the key, and run the treadmill for a few min-
utes. Repeat until the walking belt is properly tight-
ened.

c. If the walking belt still slows when walked on, see the front cover of this manual.
