Reaction Forces - Echo SRM-410X Operator's Manual

OPERATION
• Width of cutting swath depends on arc. Use a larger arc
for a wider swath, or a smaller arc for a narrow swath.
Suggested cutting width is about 1.5 m (4.9 ft).
• When scything large brush up to 0.5" diameter from
right to left, avoid cutting with highlighted section.

Reaction Forces

The cutting attachment will continue to rotate even after
◆
the throttle is released, maintain control of the unit until it
has come to a complete stop.
Blade thrust may occur when the spinning blade contacts
◆
an object that it does not immediately cut. Following
proper cutting techniques will prevent blade thrust.
Blade thrust can be violent enough to cause the unit and/or
◆
operator to be propelled in any direction, and possibly lose
control of the unit.
Blade thrust can occur without warning if the blade snags,
◆
stalls or binds.
Blade thrust is more likely to occur in areas where it is
◆
difficult to see the material being cut.
Push or Pull - Kickout
During normal use, operating a brushcutter with a circular metal blade can
produce sudden strong reaction forces that are difficult to control. Strong
reaction forces can cause a loss of balance or loss of control of the
equipment, resulting in serious injury to operator and bystanders.
Understanding what causes these reactive forces may help you to avoid
them, and can help you to maintain control of the equipment if you
experience a sudden reaction during cutting. Reactive forces occur when
the force being applied by the cutting teeth of a blade meet resistance, and
some of the cutting force is directed back toward the equipment. The
greater the cutting force or the amount of resistance, the greater the
reactive force.
