PROBLEM: The walking belt slips when walked on
SOLUTION: a. 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 adjustment bolts
clockwise, 1/4 of a turn. When the walking belt is cor-
rectly 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 carefully walk on
the treadmill for a few minutes. Repeat until the walk-
ing belt is properly tightened.
PROBLEM: The displays of the console do not function properly
SOLUTION: a. Check the batteries in the console. If the batteries need to be replaced, see page 6. Most prob-
lems are the result of drained batteries.
b. Remove the key from the console and UNPLUG THE
POWER CORD. Remove the screws from the hood.
Carefully remove the hood. Locate the Reed Switch
(86) and the Magnet (87) on the left side of the Pulley
(85). 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 1/8Ó. If
necessary, loosen the Screw (35) and move the Reed
Switch slightly. Retighten the Screw. Re-attach the
hood, and run the treadmill for a few minutes to check
for a correct speed reading.
PROBLEM: One of the upper body arms squeaks during use
SOLUTION: a. Correcting this problem requires a small amount of white marine grease, available at most
hardware stores.
Turn the Resistance Knob (61) counterclockwise until
it can be removed. Remove the Resistance Cone (98)
and the Upper Body Arm (59), along with the 3/8Ó
Washers (99), Spring Washer (101), Thrust Washers
(100), and Thrust Bearing (91). (Note: If the
Resistance Sleeve [97] comes out of the Resistance
Bracket [96], press it back in.) Apply a thin layer of
white marine grease to the outer surface of the
Resistance Cone (98). Reattach all parts in the order
shown at the right.
