Blade thrust
A blade thrust is when the product moves to the side
quickly and with force. A blade thrust occurs when the
grass blade or saw blade hits or catches on an object
that cannot be cut. A blade thrust can eject the product
or operator in all directions. There is a risk of injury to
the operator and bystanders.
The risk increases in areas where it is not easy to see
the material that is cut.
Do not cut with the area of the blade that is shown in
black. The speed and movement of the blade can cause
blade thrust. The risk increases with the thickness of the
branch that is cut.
