PRUNING

WARNING: Be alert for and guard

against kickback. Do not allow the moving

chain to contact any other branches or ob-

jects at the nose of the guide bar when prun-

ing. Allowing such contact can result in seri-

ous 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 lim bs which can catch the 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.

PRUNING T ECHNIQUE

When ready to cut, accelerate to full throttle

and apply a light cutting pressure. DO NOT

use back and forth sawing action.

1/3 through the diameter of the limb.

NOTE: When making the second and third

cuts, rest the foot of the pruner against the

tree limb that is being cut to prevent whipping
