Next, locate the
Reed Switch
(99) and the
Magnet (100)
on the left side
of the Pulley
(49). 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 necessary, loosen the
#8 x 3/4" Truss Head Screw (98), move the Reed
Switch slightly, and then retighten the Truss Head
Screw. Reattach the Motor Hood (see page 26),
and walk on the treadmill for a few minutes to
check for a correct speed reading.
SYMPTOM: The walking belt slows when walked on
a. If an extension cord is needed, use only a 3-conduc-
tor, 14-gauge (2 mm
2
) cord that is no longer than
5 ft. (1.5 m).
b. If the walking belt is overtightened, treadmill
performance may decrease and the walking belt
may become damaged. Remove the key and
UNPLUG THE POWER CORD. Using the hex key,
turn both idler roller screws (A) 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 walk on the treadmill for a few minutes.
Repeat until the walking belt is properly tightened.
c. Your treadmill features a walking belt coated with
high-performance lubricant. IMPORTANT: Never
apply silicone spray or other substances to
the walking belt or the walking platform unless
instructed to do so by an authorized service
representative. Such substances may deterio-
rate the walking belt and cause excessive wear.
If you suspect that the walking belt needs more
lubricant, see the front cover of this manual.
d. If the walking belt still slows when walked on, see
the front cover of this manual.
SYMPTOM: The walking belt is not centered
between the foot rails
The edges of the walking belt should be aligned with
the belt alignment marks (B) (see the drawing below)
on the foot rails. If necessary, follow the instructions
below to align the walking belt.
a. IMPORTANT: If the walking belt rubs against
the foot rails, the walking belt may become
damaged. 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
idler roller screw clockwise 1/2 of a turn; if the
walking belt has shifted to the right, turn the left
idler roller screw counterclockwise 1/2 of a turn.
Be careful not to overtighten the walking belt.
Then, plug in the power cord, insert the key, and
walk on the treadmill for a few minutes. Repeat
until the walking belt is centered.
