KICKBACK
WARNING: Avoid kickback which
can result in serious injury. Kickback is the
backward,upwardorsudden f orwardmotion
of the guide bar occurring when the saw
chain n earthe uppertip oftheguidebarcon-
tacts any ob ject such as a log or branch, or
when the wood closes in and pinches the
saw chainin thecut.Contactingaforeignob-
ject in the wood can also result in loss of
chain saw control.
S Rotational Kickback canoccur whenthe
moving chain contacts an object at theup-
per 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 to-
ward the operator.
S Pinch-Kickback can occur when the the
wood closes in and pinches the moving
saw chain in the cut along the top of the
guide bar and the saw 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
sawtomoveintheoppositedirection ofthe
chain rotation. The saw 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
saw chain is suddenly stopped. This sudden
stopping pulls the saw forward and away
from the operator and could easily cause the
operator to lose control of the saw.
Avoid Pinch--Kickback:
S Be extremely aware of situations or ob-
structions thatcan causematerial topinch
the t op of or otherwise stop the chain.
S Do not cut more than one log at a time.
S Do not twist the saw as the bar is with-
drawn from an undercut when bucking.
Avoid Pull--In:
S Always begin cutting with theengine atfull
speed and thesaw housing against wood.
S Use wedges made of plastic or wood.
Never use metal to hold the cut open.
