LIMBING AND PRUNING

WARNING: Be alert for and guard

against kickback. Do not allow the mov-

ing c hain to contact any other branches

or objects at the nose of the guide bar

when limbing or pruning. Allowing such

contact can result in serious injury.

WARNING: Never climb into a tree

to limb or prune. Do not stand on lad-

ders, platforms, a log, or in any position

which can cause you to lose your bal-

ance or control of the saw.

IMPORTANT POINT S

S Watch o ut for springpoles. Spring-

poles are small s ize limbs which can

whip toward you or pull y ou off b al-

ance. Use extreme c aution when c ut-

ting small size limbs.

S Be alert for springback from any

branches that are bent or under pres-

sure. Avoid being struck by the branch

or the saw when the tension in the

wood fibers is released.

S Frequently clear b ranches out of the

way to av oid tripping over them.
