Locate the two screws on the shaft cap eccentric multi (one on each side of the housing).
Slightly loosen both screws - just enough to allow the eccentric cap to rotate.
Rotate the eccentric cap to adjust belt tension. Clockwise increases tension, counterclockwise decreases tension.
Test the belt tension by pressing down on the belt between pulleys.
Once proper tension is achieved, tighten both screws to secure the eccentric cap in position.
Test the full range of motion to ensure smooth operation.
Make small adjustments - a little rotation goes a long way.
The eccentric design allows for precise tension adjustment.
Always test the full range of motion after adjustment.
