the left side of the Pulley (43). Turn the Pulley until the
Magnet is aligned with the Reed Switch. Make sure
t
hat the gap between the Magnet and the Reed
Switch is about 1/8 in. (3 mm). If necessary, loosen
t
he M4.2 x 12mm Screw (30), move the Reed Switch
slightly, and then retighten the Screw. Reattach the
Motor Hood (not shown) and run the treadmill for a
few minutes to check for a correct speed reading.
PROBLEM: The walking belt slows when walked on
SOLUTION: a. If an extension cord is needed, use only a 3-conductor, 14-gauge (1 mm
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 idler
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, 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 has shifted to the left, first re-
move the key and UNPLUG THE POWER CORD.
Using the hex key, turn the left idler roller bolt clock-
wise 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 idler roller bolt counterclockwise 1/2
of a turn. 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 idler 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.
