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 9.
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 inches 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 call toll-free 1-800-4-MY-HOME ® (1-800-
469-4663).
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. Then, 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 inches 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.
PROBLEM: The upper body arms squeak during use
SOLUTION: a. (Note: Correcting this problem requires a small amount
of white marine grease, available at hardware stores.)
Turn the Resistance Knob (A) counterclockwise and
remove it. Next, remove the Resistance Cone (B) and
the Upper Body Arm (109), along with the Resistance
Plate (C), Washers (D), Spring Washer (E), Thrust
Washers (F), and Thrust Bearing (G). (Note: If the
Resistance Plate [C] comes out of the Resistance
Cone [B], press it back in.) Apply a
thin layer of white
marine grease to the outer surface of the Resistance
Cone (B). Then, reattach all parts in the order shown
at the right.
