Lower the treadmill (see HOW TO LOWER THE
TREADMILL FOR USE on page 21). Remove the four
indicated 3/4" Screws (4), and remove the Hood (44).

Next, locate the Reed Switch (14) and the Magnet
(12) on the left side of the Pulley (11). Turn the Pulley
until the Magnet is aligned with the Reed Switch.
Make sure that the gap between the Magnet and
the Reed Switch is about 1/8 in. (3 mm). If neces-
sary, loosen the indicated Screw (29), move the Reed
Switch slightly, and then retighten the Screw. Then,
reattach the Hood (not shown) with the six 3/4"
Screws (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 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 3 to 4 in. (8 to 10
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, please 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, 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 walk-

ing belt has shifted to the right, turn the left rear
roller bolt counterclockwise 1/2 of a turn. Be careful
not to overtighten the walking belt. Plug in the power
cord, insert the key, and run the treadmill for a few
minutes. Repeat until the walking belt is centered.
