PROBLEM: The walking belt slows when walked on
SOLUTION: a. If an extension cord is needed, use only a 3-conductor, 1 mm
than 1.5 m (5 ft.).
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 5 to
7 cm (2 to 3 in.) off the walking platform. Be careful to
keep the walking belt centred. 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, call our
Customer Service Department.
PROBLEM: The walking belt is off-centre or slips when walked on
SOLUTION: a. If the walking belt is off-centre, first remove the key and UNPLUG THE POWER CORD. If the
walking belt has 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 centred.
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 5 to 7 cm (2 to 3 in.) off
the walking platform. Be careful to keep the walking belt centred. Plug in the power cord, insert the
key and carefully walk on the treadmill for a few min-
utes. Repeat until the walking belt is properly tight-
ened.
