Ryobi UT15702B manual Blade Thrust, Tri-Arc Blade, Cutting Technique - Blade, Operation

OPERATION

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

Ensure the blade has come to a complete stop before setting the brushcutter down.

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 reaction 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 occur 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.

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 06297, available at your service center.

Never use blades near sidewalks, fencing, posts, build- ings or other immovable objects.

Never use a blade after hitting a hard object without first inspecting it for damage. Do not use if any damage is detected.
