Other models and brands not listed may fit with the use of the universal adaptor, a nut, and
the red spool retainer. For these units, test the adaptor with each nut to find one that tightens
securely. Test the string head to ensure that the string will contact the cutter on the grass
shield before operating. If the string head does not fit with any of the adaptors or nuts supplied,
contact Customer Service at 1-800-860-4050 for assistance.
