Skating
FR
EN
DE
ES
IT
When the chain saw fails to dig in during a cut, the guide
bar can begin hopping or dangerously skidding along the
FR
EN
DE
ES
IT
surface of the log or branch, possibly resulting in the loss
of control of the chain saw. The sideward motion of the
FR
EN
DE
ES
IT
guide bar can increase the risk of kickback. To prevent
FR
EN
DE
ES
IT
or reduce this skating, hold the chain saw with two hands
and make sure the saw chain establishes a groove for
FR
EN
DE
ES
IT
cutting.
Bucking
FR
EN
DE
ES
IT
The process of cross cutting a felled tree or log into
FR
EN
DE
ES
IT
lengths.
Bouncing
FR
EN
DE
ES
IT
Never cut small, flexible branches or brush with your
FR
EN
DE
ES
IT
chain saw. Their size and flexbility can easily cause the
saw to bounce toward you or bind up with enough force
FR
EN
DE
ES
IT
to cause a kickback. The best tools for that kind of work
are a hand saw, pruning shears, an axe and other hand
FR
EN
DE

tools.

power.

Felling
The process of cutting down a tree.
Felling Back Cut
The final cut in a tree felling operation made on the
opposite side of the tree from the notching
undercut.
Front Hand guard
A structural barrier between the front handle of a chainsaw
and the guide bar, typically located close to the hand
position on the front handle, and sometimes employed as
an activating lever for a chain brake.
Front Handle
The support handle located at or toward the front of the
