NordicTrack NTL18530 - Manual (Page 29)

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 9.
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 allen wrench, turn both
rear roller adjustment bolts counterclockwise, 1/4 of a
turn. When the walking belt is properly tightened, you
should be able to lift each side of the walking belt 3 to
4 inches off the walking platform. Be careful to keep
the walking belt centered. Plug in the power cord, in-
sert 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, call our Customer Service Department, toll-free.
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

shifted to the left, use the allen wrench to turn the left
rear roller bolt clockwise 1/2 of a turn; if the walking belt
has shifted to the right, turn the 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.
b. If the walking belt slips when walked on, first remove the
key and UNPLUG THE POWER CORD. Using the allen
wrench, turn both rear roller bolts clockwise, 1/4 of a turn.
When the walking belt is correctly tightened, you should
be able to lift each side of the walking belt 3 to 4 inches off
the walking platform. Be careful to keep the walking belt
centered. 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.
