Adjusting Belt Tension:
Referring to figure 13.2, loosen, but do not remove, both screws labeled B. Using the correct
hex key, tightening screw C will tighten the belt (move the hex key from left to right).
Loosening screw C will loosen the belt (move the hex key from right to left). Retighten the two
screws B and run the machine in manual mode to check for proper tension. Do not over-tension
the belt. A small amount of deflection should be present when you press in on the belt between
the lower idler and upper hook pulleys. When proper tension is achieved, install the guard plate
into the machine base.
Adjusting Tension Plate Alignment:
Referring to figure 13.3, during the belt tension procedure, it is possible for the tension plate to
become misaligned. This misalignment may result in an audible “chirp” from the belt. To
correct the misalignment, loosen the two screws labeled B in figure 13.2 and lightly pry between
the tension plate and hook assembly housing with a small screw driver. Retighten the two screws
labeled B and confirm proper operation of the belt drive. When proper alignment is achieved,
install the guard plate into the machine base.

Adjusting Belt Tracking:
Tracking adjustments are no longer needed with the addition of flanged pulleys on the tensioner.
Note: It is normal for the belt to “walk” in and out on the pulleys a small amount when the
machine is running.
