Proper pulley alignment prevents premature
V-belt wear and proper power transfer from the
motor. The pulleys are properly aligned when
they are parallel and in the same plane as each
other.
— If pulleys are parallel and in the same
plane, no adjustment is necessary.
— If pulleys are not parallel or in the same
plane, remove rear access panel, then
proceed to Step 4.
