QUILL RETURN SPRING ADJUSTMENT:
Spring tension for return of spindle, after hole drilling, has been pre-set at the factory. No fur-
ther adjustment should be attempted unless absolutely necessary. Adjustment will probably be
required if a multiple drilling or tapping head is used. If adjustment is necessary, loosen lock screw
while holding. Do not allow the housing to turn in your hand, or spring will unwind. Turn entire
housing assembly clockwise the number of turns necessary to cause the quill to return to its up
position. (NOTE. The flat of the spring housing pilot is lined up with the spring loading hole on the
body of the spring housing.) Reset lockscrew make sure point of screw mates to flat on the housing
journal.
