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 10.

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 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 inches
off the walking platform. Be careful to keep the walk-
ing 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, 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

belt has shifted to the left, use the allen wrench to
turn the left rear roller bolt clockwise 1/2 of a turn;

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. Then, plug in the
power cord, insert the key, and run the treadmill for a
few minutes. Repeat until the walking belt is centered.

If the walking belt slips when walked on, first re-
move the key and

UNPLUG THE POWER CORD.

Using the allen wrench, turn both rear roller bolts
