Basic Working Technique - Stihl MSA 220.0 T Instruction Manual

English
WARNING
■ Pushback occurs when the chain on the top of
the bar is suddenly stopped or significantly
slowed when it is pinched, caught or encoun‐
ters a foreign object in the wood. The reaction
of the chain may drive the saw rapidly straight
back toward the operator, causing loss of con‐
trol 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 withdraw‐
ing the bar from an underbuck cut because
the chain can pinch or bind.
► Cut with a sharp, properly tensioned chain.

Basic Working Technique

7.1 Intended Uses
WARNING
■ This lightweight chain saw equipped with a top
handle is designed specifically for in-tree use.
■ This chain saw is not designed for felling trees
or other cutting operations on the ground.
■ Before starting any cutting operation, fully
charge your battery and ensure that all cuts
necessary can be completed on a single
charge.
► Fully charge the battery before starting
work.
► Ensure that all necessary cuts can be com‐
pleted using the existing charge before
starting.
■ Position the chain saw in such a way that your
body is clear of the cutting attachment when‐
ever the motor is running.
7.2 Pruning
Pruning is selectively removing branches from a
standing tree.
WARNING
■ To reduce the risk of injury from loss of con‐
trol:
► Do not use the chain saw one-handed.
► Never operate the chain saw above shoul‐
der height or cut overhead.
► Do not overreach.

► If you are unable to follow these instruc‐
tions, you must use a different tool, such as
a pole pruner.
► If conditions permit, work from a lift bucket.
■ 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 buck‐
ing.
■ 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.
To cut branches from a standing tree:

► 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.
