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.
Inspect the blade for damage before proceeding. Sharpen teeth if dull, or
replace blade if cracked, bent, missing teeth, or otherwise damaged.
To prevent binding:
• Keep blades sharp
• Avoid excessive pressure during cuts
• Don’t exceed cutting capacity of blade
• Don’t use blades with damaged or missing cutting teeth
• Don’t rock blades in cut
