KICKBACK
WARNING: Avoid kickback which
can result in serious injury. Kickback is the
backward, upward or sudden forward motion
of the guide bar occurring when the chain
near the upper tip of the guide bar contacts
any object such as a log or branch, or when
the wood closes in and pinches the chain in
the cut. Contacting a foreign object in the
wood can also result in loss of control.
S
Rotational Kickback can occur when the
moving chain contacts an object at the upper
tip of the guide bar. This contact can cause
the chain to dig into the object, which stops
the chain for an instant. The result is a
lightning fast, reverse reaction which kicks the
guide bar up and back toward the operator.
S Pinch-Kickback can occur when the wood
closes in and pinches the moving chain in
the cut along the top of the guide bar and the
chain is suddenly stopped. This sudden
stopping of the chain results in a reversal of
the chain force used to cut wood and
causes the pruner to move in the opposite
direction of the chain rotation. The pruner is
driven straight back toward the operator.
S Pull-In can occur when the moving chain
contacts a foreign object in the wood in the cut
along the bottom of the guide bar and the
chain is suddenly stopped. This sudden
stopping pulls the pruner forward and away
from the operator and could easily cause the
operator to lose control of the pruner.
REDUCE THE CHANCE OF
KICKBACK
S Recognize that kickback can happen. With
a basic understanding of kickback, you can
reduce the element of surprise which
contributes to accidents.
S Never let the moving chain contact any
object at the tip of the guide bar.
S Keep the working area free from
obstructions such as other trees, branches,
rocks, stumps, etc. Eliminate or avoid any
obstruction that your chain could hit while
you are cutting. When cutting a branch, do
not let the guide bar contact branch or other
objects around it.
S Keep your chain sharp and properly
tensioned. A loose or dull chain can
increase the chance of kickback occurring.
Follow manufacturer’s chain sharpening
and maintenance instructions. Check
tension at regular intervals with the engine
stopped, never with the engine running.
Make sure the bar clamp nut is securely
tightened after tensioning the chain.
S Begin and continue cutting at full speed. If
the chain is moving at a slower speed, there
is greater chance of kickback occurring.
S Cut one branch at a time.
S Use extreme caution when re-entering a
previous cut.
