ENGLISH
As shown in the illustration, a blade turning
counterclockwise will cause the equipment to pull
away from the operator if the point of cutting
resistance is on the left side of the blade. If the point
of cutting resistance is on the right side of the blade,
the equipment will push back toward the operator. In
both examples, the reactive force is in the opposite
direction of blade rotation at the contact point where
resistance occurs.
Kickout
Kickout is also a reactive force caused by
resistance to cutting, but the direction of blade
thrust is lateral (to the left or right of the blade),
instead of forward or back toward the operator.
In most cases, Push, Pull, and Kickout can be
reduced or eliminated by:
• Using the correct blade for the cutting job
• Using properly sharpened blades
• Applying consistent, even force to the blade
during the cut
• Avoiding obstacles and ground hazards
• Using extra care when cutting harder materials such as extremely dry
brush, saplings, and small trees
• Cutting from a stable, secure position
Blade Cutting Problems
Binding - Blades may bind in the cut if dull or forced. Binding can damage
blade, and result in blade breakage or injury from fragments and flying
debris. If a blade binds in a cut, don’t try to get it out by applying “up and
down” force to pry the cut open. Applying prying force to the blade can bend
the blade, and result in blade failure and injury.
To free a blade that is bound in the cut, stop the engine, and support the
trimmer or brushcutter to keep stress off the blade. Push the tree away from
the entry point of the cut to open the cut, and pull the blade directly away
from the cut in a straight-line motion. Use caution when releasing the tree to
avoid being struck by spring-back or falling.
