c. If the walking belt slips when walked on, first re-
move the key and UNPLUG THE POWER CORD.
Using the allen wrench, turn both rear roller adjust-
ment 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
run the treadmill for a few minutes. Repeat until the
walking belt is properly tightened.
PROBLEM: The walking belt slows when walked on
SOLUTION: a. Use only a single-outlet surge suppressor that is UL 1449 listed as a transient voltage surge sup-
pressor (TVSS). The surge suppressor must have a UL suppressed voltage rating of 400 volts or
less and a minimum surge dissipation of 450 joules. The surge suppressor must be electrically
rated for 120 volts AC and 15 amps.
b. If the walking belt is overtightened, treadmill perfor-
mance may decrease and the walking belt may be per-
manently 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,
insert the key and run the treadmill for a few minutes.
Repeat until the walking belt is properly tightened.
