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 a barrier bar that is located in front of the opera-
tor to reduce the risk of the operator from coming in contact with the cutting attachment (per ANSI B175.3). When
using a blade, the unit must also be equipped with a harness or strap.
