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 using a blade, the unit must be equipped with a harness or strap.
Using A Brushcutter Blade WARNING! Before working with a blade-equipped unit, always inspect and clear the area of objects that could interfere with or damage the blade. Never use a blade near sidewalks, fence posts, buildings or other objects that could cause injury or damage. Never use a blade for purposes other than those for which it was designed. Whenever you strike a hard object with a blade, always stop the brushcutter and carefully inspect the blade for damage.
