WARNING!
A standard grass trimmer unit with loop handle should NEVER be operated with
blade-type attachments. For blade use, the trimmer must be fitted with a bicycle-type
handlebar or barrier bar that is located in front of the operator to reduce the risk of the
operator coming in contact with the cutting attachment. (Per ANSI B175.3). When us-
ing a blade, the unit must also be equipped with a harness or strap.
The T272X should now be
completely assembled and ready for use with a trimmer head.
