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 7.
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 2 to
3 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 when walked on, please call our toll-free HELPLINE.
PROBLEM: The walking belt is off-center or slips when walked on
SOLUTION: a. If the walking belt has shifted to the left, first re-
move the key and UNPLUG THE POWER CORD.
Using the allen wrench, turn the left rear roller bolt
clockwise 1/2 of a turn. Be careful not to overtighten
the walking belt. If the walking belt has shifted to
the right, turn the left rear roller bolt counterclockwise
1/2 of a turn. 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 allen wrench, turn both rear roller bolts clockwise,
1/4 of a turn. When the walking belt is correctly tight-
ened, you should be able to lift each side of the walk-
ing belt 2 to 3 inches off the walking platform. Be
careful to keep the walking belt centered. 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: ONE OF THE UPPER BODY ARMS SQUEAKS DURING USE
SOLUTION: a. Correcting this problem requires a small amount of
white marine grease, available at most hardware
stores. Turn the Resistance Knob (98) counterclock-
wise until it can be removed. Remove the Resistance
Cone (93) and the Upper Body Arm (89), along with
the 3/8" Washers (57), Spring Washer (95), Thrust
Washers (96), and Thrust Bearing (97). (Note: If the
Resistance Sleeve [92] comes out of the Resistance
Bracket [91], press it back in.) Apply a thin layer of
white marine grease to the outer surface of the
Resistance Cone (93). Reattach all parts in the order
shown at the right.
