PROBLEM: The walking belt slows when walked on
SOLUTION: a. If an extension cord is needed, use only a 3-conductor, 14-gauge (1mm
2
) 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 7
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 minutes.
Repeat until the walking belt is properly tightened.
c. If the walking belt still slows when walked on, please see the front cover of this manual.
PROBLEM:
The walking belt is off-center or slips when walked on
SOLUTION: a. If the walking belt is off-center, first remove the key
and UNPLUG THE POWER CORD. If the walking
belt has shifted to the left, use the hex key to turn
the left rear roller bolt clockwise 1/2 of a turn; if the
walking belt has shifted to the right, turn the left
bolt counterclockwise 1/2 of a turn. Be careful not to
overtighten the walking 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
UNPLUG THE POWER CORD. Using
the hex key, turn both rear roller bolts clockwise, 1/4
of a turn. When the walking belt is correctly tightened,
you should be able to lift each edge of the walking
belt 2 to 3 in. (5 to 7 cm) off the walking platform. Be
careful to keep the walking belt centered. Then, plug
in the power cord, insert the key, and carefully walk
on the treadmill for a few minutes. Repeat until the
walking belt is properly tightened.
