Blade Cutting Problems - Echo U29515001001 Operator's Manual

SRM-2320T
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.
