English 7 Proper Techniques for Basic Bucking, Limbing, Pruning and Felling
￭ When cutting smaller logs, make sure the log is properly
supported to reduce the risk of personal injury from loss of
control of the chain saw or movement of the log. Small
logs can move when contacted by the teeth of the chain:
– Place logs through "V-shaped" supports on top of a
sawhorse whenever possible.
– Never permit another person to hold the log.
– Never stabilize the log with your leg or foot.
￭ Failing to control the saw at the bottom of a bucking cut
can cause severe personal injury or death.
– Prepare the saw to exit the bottom of the cut by
reducing the feed force you exert on the saw.
– Cushion the weight of the saw so that the bar and
chain are not thrust downward into your lower body
and legs as the bar/chain exits the cut.
When bucking:
► Position the bumper spike of the saw against the log and
use it as a fulcrum.
► Continually repositioning the bumper spike while pushing
the guide bar completely through the log.
7.2 Cutting Logs Under Tension
WARNING
￭ There is an increased danger of pinching the chain saw
when cutting logs under tension. The tension in wood can
also release suddenly and with great force, propelling the
log, limb or chain saw into the saw operator, causing injury
or loss of control.
￭ To reduce the risk of severe or fatal personal injury from
reactive forces, including kickback, or loss of control when
cutting wood under tension:
– Always start with a relieving cut (1) at the
compression side of the log, and then make a
bucking cut (2) at the tension side.
– If a pinch occurs that traps the bar/chain, shut off the
engine and activate the chain brake before
attempting to remove the saw from the log,
exercising caution that the limb does not suddenly
snap or release.
￭ Working in areas where logs, limbs and roots are tangled
is extremely dangerous.
– Drag the logs, limbs and other material to be cut into
a clear area before cutting. Pull out exposed and
cleared logs first. Do not cut where the tip of the bar
may come into contact with other logs, limbs or leafy
material.
