With the help of a second person, carefully raise the
Uprights (84) to the position shown. Next, carefully
pivot the Hood (41) off.
Locate the Reed Switch (63) and the Magnet (46) on
the left side of the Pulley (47). Turn the Pulley until the
Magnet is aligned with the Reed Switch. Make sure
that the gap between the Magnet and the Reed
Switch is about 3 mm (1/8 in.). If necessary, loosen
the Screw (3), move the Reed Switch slightly, and
then retighten the Screw. Reattach the Hood, and run
the treadmill for a few minutes to check for a correct
speed reading.
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
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 5–7 cm (2–3 in.) off the walk-
ing platform. Be careful to keep the walking belt cen-
tred. Then, plug in the power cord, insert the key, and
walk on the treadmill for a few minutes. Repeat until the
walking belt is properly tightened.
c. If the walking belt still slows when walked on, see the front cover of this manual.
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 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 centred.
