Pulley alignment is an important factor in power
transmission and belt life. The pulleys should be
parallel to each other and in the same plane (co-
planer) for optimum performance.
Each pulley can be adjusted by loosening the set
screw that secures the pulley to the shaft, sliding
the pulley in/out, and retightening the set screw to
lock the pulley in place.
