English
trunk may split and come back toward the
operator (barber-chairing), or the tree may
jump back off the stump.
■ Always position yourself and your equipment
away from material being removed.
■ When the material starts to fall, withdraw the
bar and release the trigger switch. After finish‐
ing a cut, activate the chain brake before
changing position in the tree.
WARNING
■ This chain saw is not designed for cutting
large diameter trees, and using it to cut large
diameter trees could result in an inability to
control the fall, which can lead to serious or
fatal personal injury.
■ Before starting any cutting operation, make
sure the saw you are using has sufficient size,
power and run-time to complete the cutting
task efficiently and without re-charging. Alter‐
natively, have multiple charged batteries avail‐
able for use, select a more powerful chain
saw, or select a more powerful battery.
■ There are a number of factors that may affect
the intended direction of fall, e.g., wind direc‐
tion and speed, lean of tree, surrounding trees
and obstacles, sloping ground, wood structure,
or decay.
► To reduce the risk of severe or fatal injury
to yourself or others, look for, analyze and
plan for these conditions prior to beginning
the cut.
► Removing portions of a tree with a diameter
greater than the effective cutting length of
the guide bar requires use of special cutting
techniques (e.g., sectioning method, plunge
cut). These methods can be extremely dan‐
gerous because they involve the use of the
nose of the guide bar and can result in kick‐
back. Only properly trained professionals
should attempt these techniques.
■ Trees that are split, decayed or rotted inside,
or that are leaning or otherwise under tension,
are more likely to snap or split while being cut,
causing serious or fatal injury to the operator
or bystanders.
► Inexperienced users should never attempt
to cut such trees.
► Look for broken or dead branches which
could vibrate loose and fall on the operator.
Certain types of trees are more susceptible
to this condition, such as Douglas firs.
► Always observe and be aware of the gen‐
eral condition of the tree.
