Blade Cutting Problems - Echo Pro Attachment Series Operator's Manual

DPAS-2100
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 unit, 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
