Cutting Branches Under Tension - Stihl MSA 220.0 T Instruction Manual

English
￭ This lightweight chain saw is equipped with a top handle
and is designed specifically for in-tree use. If the operator
is not properly secured for two-hand use when using this
saw in a tree, there is an increased risk of injury from loss
of control.
￭ For this reason, this chain saw should be used only for
work in a tree by persons trained in special cutting and
working techniques. This type of chain saw is not
designed for cutting work on the ground, such as felling
and bucking.
￭ Because this chain saw is not intended for use on the
ground, this manual does not contain instructions for
felling trees or for limbing and bucking felled trees. For
instructions on these techniques when using other STIHL
chain saw models, see the instruction manuals for these
other saws or the STIHL Chain Saw Safety Manual, which
is available free of charge online or from your authorized
STIHL dealer.
￭ To reduce the risk of injury:
– Never position yourself directly underneath the
branch you are cutting.
– Watch for falling branches. Keep sufficient distance
away from the falling wood.
When pruning, precut branches when necessary to help
avoid splitting wood or tearing bark.

► Make the first cut (1) on the underside (A) of the branch.
Cut through approximately 1/4 of the diameter of the
branch.
► Make the second cut (2) on the top side (B) of the branch,
directly above the first cut.
► Make the third (finishing) cut (3) closer to the trunk,
leaving adjacent bark firmly attached.
Other acceptable techniques for pruning trees can be found
in ANSI A300.

WARNING
￭ There is an increased danger of pinching the chain saw
when cutting branches under tension. The tension in wood
can also release suddenly and with great force, propelling
the limb or chain saw into the saw operator, causing injury
or loss of control.
