PROBLEM: The walking belt slows when walked on
SOLUTION: a. If an extension cord is needed, use only a 3-conductor, 1mm
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 hex key, 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, please 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 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 bolt
counterclockwise 1/2 of a turn. Be careful not to over-
tighten 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 re-
move the key and UNPLUG THE POWER CORD.
Using the hex key, turn both rear roller bolts clock-
wise, 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 plat-
form. 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 minutes. Repeat until the
walking belt is properly tightened.
PROBLEM: The incline of the treadmill does not change correctly
SOLUTION: a. With the key in the console, press one of the Incline buttons. Whilst the incline is changing, re-
move the key. After a few seconds, reinsert the key. The treadmill will automatically rise to the
maximum incline level and then return to the minimum level. This will recalibrate the incline system.
