Cutting Logs Under Tension - Stihl MSA 120 C Manual De Instrucciones

8 Proper Techniques for Basic Bucking, Limbing, Pruning and Felling
￭ To reduce the risk of injury:
– Never stand directly underneath the branch you are
cutting.
– Watch for falling branches. As soon as the branch
starts to fall, step aside and keep a sufficient
distance away from the falling wood. A branch may
spring back at you after it hits the ground.
– Prior to beginning work, clear the work area of limbs
and brush to reduce the risk of tripping and losing
control of the chain saw.
To cut branches from a standing tree:
1
► Make the first cut (1) on the underside of the branch,
approximately 2 in. (5 cm) from the trunk. Cut through
approximately 1/4 of the diameter of the branch. This will
help prevent the branch from splintering after it is cut.
► Make the second cut (2) on the top side of the branch,
approximately 2 in. (5 cm) from the first cut.
► As soon as the branch starts to fall, withdraw the chain
saw and let the branch fall to the ground.

WARNING
￭ There is an increased danger of pinching the chain saw
when bucking 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, switch off
the motor, activate the chain brake, remove the
battery and 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
("blow down" areas) 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.
