PRUNING
WARNING: Be alert for and guard
against kickback. Do not allow the moving
chain to contact any other branches or objects
at the nose of the guide bar when pruning. Al-
lowing such contact can result in serious injury.
IMPORTANT POINTS
S W ork slowly, keeping both hands firmly
gripped on the pruner. Maintain secure
footing and balance.
S Plan cut carefully. Check direction branch
will fall.
S Watch out for springpoles. Springpoles are
small size limbs which can catch t he chain
and whip toward you or pull you off balance.
Use extreme caution when cutting small size
limbs or slender material.
S Watch out for branches immediately behind
the branch being pruned. If the chain hits the
rear branch, damage to the unit may occur.
S Be alert for springback. Watch out for
branches that are bent or under pressure.
Avoid being struck by the branch or the
pruner when the tension in the wood fibers
is released.
S Keep a clear work area. Frequently clear
branches out of the way to avoid tripping
over them.
S Long branches should be removed in
several pieces.
