must be in-line (in the same plane) within 1/32" to assure
belt alignment within grooves. To check alignment, dis-
connect electrical power and remove the beltguard.
Place a straightedge against the outside of the flywheel
and measure the distance from it to the nearest groove.
Alignment is achieved when the other end of the straigh-
tedge is within 1/32" of the measured dimension at the
pulley grooves.
