Pushback

WARNING
￭ Pushback occurs when the chain on the top of the bar is
suddenly stopped or significantly slowed when it is
pinched, caught or encounters a foreign object in the
wood. The reaction of the chain may drive the saw rapidly
straight back toward the operator, causing loss of control
which, in turn, may cause serious or fatal injury.
￭ Pushback usually occurs when the top of the bar is used
for cutting.
￭ To reduce the risk of pushback:
– Be alert to forces or situations that may cause
material to pinch or bind the top of the chain.
– Do not cut more than one log at a time.
– Do not twist the chain saw when withdrawing the bar
from an underbuck cut because the chain can pinch
or bind.
– Cut with a sharp, properly tensioned chain.
