ProForm 775 CT PFTL72707.0 - Manual (Page 22)

Locate the Reed Switch (63) and the Magnet (46) on
the left side of the Front Roller (47). Turn the Front
Roller 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 nec-
essary, move the Reed Switch slightly using a slotted
screwdriver. Reattach the Hood (not shown), making
sure that the Screws (not shown) are inserted into the
same holes from which they were removed. Then, 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 the specifications described on page 10.
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 2 to 3 in. (5 to 8
cm) above 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 tight-
ened.
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, 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 rear roller bolt clockwise 1/2 of a turn;
if the
walking belt has shifted to the right, turn the left
bolt counterclockwise 1/2 of a turn. Be careful not to
overtighten the walking belt. Then, plug in the power
cord, insert the key, and run the treadmill for a few
minutes. Repeat until the walking belt is centered.
