Adjust Pulley Screws
1. Use the controlling equipment to set the belt speed to 4 or 5
miles per hour (7 or 8 kilometers per hour).
2. To correct a belt that tracks to the right, turn the right pulley
adjustment screw CLOCKWISE in 1/8-turn increments until the
belt tracks in the center. Wait 2 or 3 minutes between each 1/8-
turn to allow the belt position to stabilize.
To correct a belt that tracks to the left, turn the left pulley
adjustment screw CLOCKWISE in 1/8-turn increments until the
belt tracks in the center. Wait 2 or 3 minutes between each 1/8-
turn to allow the belt position to stabilize.
3. If either adjustment in step 2 results in an over-adjustment of
the belt tracking, loosen the pulley screw that was tightened and
wait several minutes for the treadmill belt position to stabilize.
Then tighten the other pulley adjustment screw.
NOTE
Make adjustments to the pulley screws in
small increments. Over-adjustments and
repeated tightening of the screws can cause
too much tension on the belt.
