5. SYMPTOM: THE WALKING BELT IS OFF-CENTER WHEN WALKED ON
a. If the walking belt has shifted to the left, first remove the key and
UNPLUG THE POWER CORD. Using the 3/16” end of the allen
wrench, turn the left rear roller adjustment bolt clockwise, and
the right bolt counterclockwise, 1/4 of a turn each. 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 centered.
b. If the walking belt has shifted to the right, first remove the key
and UNPLUG THE POWER CORD. Using the 3/16” end of the
allen wrench, turn the left rear roller adjustment bolt counter-
clockwise, and the right bolt clockwise, 1/4 of a turn each. 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 centered.
c. If the walking belt slips when walked on, first remove the key
and UNPLUG THE POWER CORD. Using the 3/16” end of the
allen wrench, turn both rear roller adjustment 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 2-3 inches off
the walking platform. The center of the walking belt should just
touch 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 prop-
erly tightened.
6. SYMPTOM: ONE OF THE UPPER BODY ARMS SQUEAKS DURING USE
a. Correcting this problem requires a small amount of white marine
grease, available at most hardware stores.
Turn the Resistance Knob (97) counterclockwise until it can be
removed. Remove the Resistance Cone (98) and the Upper
Body Arm (96), along with the 3/8” Washers (67), Spring
Washer (5), Thrust Washers (101), and Thrust Bearing (102).
(Note: If the Resistance Sleeve [99] comes out of the
Resistance Bracket [104], 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.
7. SYMPTOM: THE DISPLAYS OF THE CONSOLE DO NOT FUNCTION PROPERLY
a. Check the batteries in the console. (See BATTERY INSTALLATION on page 8.) Most problems are the re-
sult of drained batteries.
b. If the speed display does not show a correct reading, remove the
key and UNPLUG THE POWER CORD. Raise the treadmill to
the storage position. (See HOW TO FOLD THE TREADMILL
FOR STORAGE on page 10.) Remove the four indicated screws.
Next, lower the treadmill. (See HOW TO LOWER THE TREAD-
MILL FOR USE on page 11). Remove the four screws from the
sides of the hood. Carefully slide the hood forward and remove it.
See page 14 for further instructions.
