Locate the Reed Switch (53) and the Magnet (51) on
the left side of the Pulley (55). Turn the Pulley until
the Magnet is aligned with the Reed Switch. Make
s
ure that the gap between the Magnet and the
Reed Switch is about 1/8 in. (3 mm). If necessary,
l
oosen the M4.2 x 13mm Tek Screw (20), 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. Use only a single-outlet surge suppressor that meets all of the specifications described on page 13.
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 min-
utes. Repeat until the walking belt is properly tight-
ened.
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 re-
move the key and UNPLUG THE POWER CORD.
Using the hex key, turn both idler roller bolts clock-
wise, 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 plat-
form. Be careful to keep the walking belt centered.
Then, plug in the power cord, insert the key, and care-
fully walk on the treadmill for a few minutes. Repeat
until the walking belt is properly tightened.
