Operating the Brushcutter, Blade Thrust

OPERATION

OPERATING THE BRUSHCUTTER

See Figures 19 - 20.

Hold the brushcutter with your right hand on the rear handle and the your hand on the “J” Barrier Handle. Keep a firm grip with both hands while in operation. Brushcutter should be held at a comfortable position with the rear handle about hip height. Maintain your grip and balance on both feet. Position yourself so that you will not be drawn off balance by the kickback reaction of the cutting blade.

Adjust the shoulder harness to position the brushcutter at a comfortable operating position and to assure that the shoulder harness will reduce the risk of operator contact with the blade.

BLADE THRUST

Exercise extreme caution when using the blade with this unit. Blade thrust is the reaction that may occur when the spinning blade contacts anything it cannot cut. This contact may cause the blade to stop for an instant, and suddenly “thrust” the unit away from the object that was hit. This re- action can be violent enough to cause the operator to lose control of the unit. Blade thrust can occur without warning if the blade snags, stalls, or binds. This is more likely to oc- cur in areas where it is difficult to see the material being cut. For cutting ease and safety, approach the weeds being cut with the brushcutter from the right to the left. In the event an unexpected object or woody stock is encountered, this practice could minimize the blade thrust reaction.

WARNING:

To avoid burns from hot surfaces, never operate unit with the bottom of the engine above waist level.

TRI-ARC®BLADE

The Tri-Arc®blade is suited only for thicker weeds and pulpy stalks. When the blade becomes dull, it can be turned over to extend the life of the blade. Do not sharpen the Tri-Arc®blade.

Use only Tri-Arc®blade, part number AP04105, available at your local retailer.
