Model G0857/G0858 (Mfd. Since 07/19)
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
(coplaner) 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.
