S Watch out for springpoles. Use extreme caution when cutting small size limbs. Slen- der material may catch saw chain and be whipped toward you or pull you off balance.
S Be alert for springback. Watch out for branches that are bent or under pressure. Avoid being struck by the branch or the saw when the tension in the wood fibers is released.
SFrequently clear branches out of the way to avoid tripping over them.
LIMBING
SAlways limb a tree after it is cut down. Only then can limbing be done safely and prop- erly.
S Leave the larger limbs underneath the felled tree to support the tree as you work.
SStart at base of the felled tree and work to- ward the top, cutting branches and limbs.
Remove small limbs with one cut.
SKeep the tree between you and the chain
as much as possible.
SRemove larger, supporting branches with the 1/3, 2/3 cutting techniques described in
BUCKING WITHOUT A SUPPORT.
S Always use an overcut to cut small and freely hanging limbs. Undercutting could cause limbs to fall and pinch saw.
PRUNING
WARNING: Limit pruning to limbs shoulder height or below. Do not cut if branches are higher than your shoulder. Get a professional to do the job.
SMake your fist cut 1/3 of the way through the bottom of the limb.
SNext make a 2nd cut all the way through the limb. Then cut a third overcut leaving a 1 to 2 inch collar from the trunk of the tree.
