Check your belt tension. There should be 1 1/8" pinch ..squeeze the
bottom belt on the motor together and there should be no more than a
total of 1 1/8" deflection. If there is..lower the motor until it is
correct.

If it is correct..and still changing slowly....install a VFD and do
away with the vari drive. Stick in a 2hp drive from Automation Direct
or used on Ebay.
