D. DEBRANCHING AND PRUNING
• Work slowly, keeping both hands on the saw
with a firm grip. Maintain secure fppting and bal­
ance.
• Watch out for springpoles. Use extreme caution
when cutting small size iimbs. Slender material may
catch the saw chain and be whipped toward you or
pull off balance.
Be alert for sprlngback. Watch out for branches
that are bent or under pressure as you are cutting to
avoid being struck by the branch or the saw when the
tension in the wood fibers is released.
Keep a clear work area. Frequently clear branches
