7. SYMPTOM: THE SURFACE OF THE WALKING PLATFORM IS DAMAGED
a. Both sides of the walking platform are designed to be used as walking surfaces. If the surface becomes
damaged, or if there is any wood showing through the coating, the walking platform can be turned over. The
walking platform typically needs to be turned over after approximately 6,000 to 7,500 miles. Follow the in-
structions below to turn over the walking platform.
Remove the key and unplug
the power cord. Remove the
two Hood Screws (2) and lift off
the Motor Hood (1). Next, re-
move the two Rear Roller Bolts
(82), the two Roller Guard
Screws (80), and the Right and
Left Roller Guards (81, 83).
Remove the six Platform
Screws (6). Lift the Rear Roller
(79) and slide it out of the
Walking Belt (71). Lift the
Walking Platform (70) a few
inches, slide it out of the
Walking Belt, turn it over, and
then slide it back into the
Walking Belt. Slide the Rear
Roller back into the Walking
Belt. Reattach the six Platform Screws (6). Reattach the Right and Left Roller Guards (81, 83) with the two
Roller Guard Screws (80). Insert the Rear Roller Bolts (82) into the Roller Guards and thread them into the
Rear Roller (79). Reattach the Motor Hood (1) with the two Hood Screws (2).
Next, the Walking Belt (71) will need to be adjusted to
the proper tension. Using chalk, make two marks exactly
50” apart on the Walking Belt as shown in the drawing.
Then, tighten both Rear Roller Bolts (82) until the two
chalk marks move apart an additional 3/16” to 1/4”. Make
sure to keep the Walking Belt centered.
