with plastic cap(s) that prevents counterclockwise rotation
from the original factory adjustment. If your unit exhibits
specific performance problem(s) where the Trouble Shooting
Section recommends a counterclockwise needle adjustment
and no adjustments have been made since original pur-
chase, the unit should be taken to a factory authorized
service dealer for repair. In most cases, the needed adjust-
ment is a simple task for the factory trained service repre-
sentative.
