side of the treadmill, and then pull it out of the treadmill.
8. Remove the rear roller by pulling it straight back past the side rails and then out
of the belt.
7. Lift the outside edges of the running belt. On each side of the running deck are
three bolts that hold the running deck to the cushioned supports. Remove all six
Allen-head bolts.

located over both sprockets.
13. After you have completed the installation, and before you tension the belt, make
two visible marks, 50 in. apart, on the belt (if such marks are not already
present). Tighten the rear roller take-up bolts evenly until the two marks are
exactly 50-1/4” apart. This will provide the ½% tension recommended by the
belt manufacturer.

Adjustment” on page
