WARNING!

A standard grass trimmer with a loop handle should NEVER be operated with blade-type attachments. For blade use the trimmer must be fitted with a bicycle-type handlebar or loop handle with a barrier bar that is located in front of the operator to reduce the risk of the operator from coming in contact with the cutting at- tachment (per ANSI B175.3). When using a blade, the unit must also be equipped with a harness or strap.

To install a

trimmer head onto a T231X, first remove the shaft bolt, bolt guard and safety clip (see the next
