GLOSSARY - Pole Pruners
A dominant upright stem, usually the main trunk. There
can be several leaders in one tree.
Same as branch, but larger and more prominent.
To hinder, block, close off, or be in the way of; to hinder
or retard a desired effect or shape.
The tree trunk; or a large limb from which lateral
branches grow.
Specifically the closing-in of the wood which pinches
and stops the saw chain along the top rails of the
guide bar during a cut. This can result in the saw being
propelled straight back toward the operator (called a
Linear Kickback). Pinch can also occur on the lower
rails of the guide bar, resulting in the saw being pulled
away from the operator.
The two-step process to remove a branch before
the finished cut is made so as to prevent splitting or
bark tearing into the parent stem. The branch is first
undercut, then cut from the top before the final cut.
Removal of plant parts.
A moving blade that alternately changes direction on a
linear cutting axis.
A saw chain which has been demonstrated to reduce
kickback on some saw models during ANSI testing.
A sheath to cover the saw chain and guide bar during
transport and at other times when the pruner is not in
use.
When the guide bar and saw chain or blade fails to
dig in during a cut, the guide bar or blade can begin
hopping or dangerously skidding along the surface of
the branch, possibly resulting in the loss of control of
the pruner. To prevent or reduce skating, properly hold
the pruner with two hands and make sure the saw chain
or blade has established a groove for cutting.
Be alert for spring poles and stay clear of them during
cutting. A spring pole can spring suddenly when cut,
or when the wood holding it down is cut away. A spring
pole can strike you or deflect the saw into your body
An undesirable short length of a branch remaining after
a break or incorrect pruning cut is made.
Structural blade or housing damage resulting from
jamming in a cut, using the guide bar/blade as a lever,
dropping the unit, or other abuse.
Branch that assumes the dominant vertical position on
the top of a tree.
