STEP 7
Adjust Walk Belt Tightness
As you exercise, does the walk belt suddenly pause and then regain traction? Or, if you
bear down against the walk belt, does the belt not pause whatsoever? If either of these
two conditions occur, the walk belt may be too loose or too tight. In this case, please
turn off the treadmill and adjust walk belt tightness. To inspect a walk belt, lift it at the
center of the deck as shown in Figure A,B. The walk belt should lift 30 mm (1 1/8 inch)
or to 3 kg (6.6 lb.). If the walk belt is too loose, turn rear roller screws clockwise one-
half rotation at a time and retest tightness. If the walk belt is too tight, turn rear roller
screws counterclockwise one-half rotation at a time and retest tightness. Perform the
same procedure until the walk belt is neither too tight nor too loose. Do not turn rear
roller screws in excess of these amounts without first testing for proper tightness.
Note: Set the gap between the end of the finger guard and the rear roller to 2 mm. If
this gap exceeds 6 mm, follow lubrication procedures to remove left and right landing
strips, loosen finger guard screws, and slide the finger guards into place as shown in
illustration C.
