OPERATION
BLADE THRUST
Exercise extreme caution when using a blade attachment
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 brush cutter 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.
