8 Proper Techniques for Basic Bucking, Limbing, Pruning and Felling
7.4

Pushback

WARNING
￭ Pushback occurs when the saw 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 saw chain may drive the chain
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 saw 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 saw chain can
pinch or bind.
– Cut with a sharp, properly tensioned chain.

Intended Uses

WARNING
￭ This chain saw is not designed for felling large trees or
cutting large diameter logs.
￭ Position the chain saw in such a way that your body is
clear of the cutting attachment and the extension cord
whenever the motor is running. Stand to the left of the cut
while bucking, outside of the cutting plane.
8.2

Bucking

Bucking is cutting a log into sections.
WARNING
￭ Be aware of rolling logs. Rolling logs can cause serious or
fatal personal injury. To prevent a log from rolling while
bucking:
– Make sure the log is secure and will not roll downhill
before starting your cut. If necessary, use sturdy
wedges, shims or chocks.
– If on a slope, always stand on the uphill side of the
log.
– Never stand on the log.
