saw when the tension in the wood fibers is released.
SKeep a clear work area. Frequently 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 the base of the felled tree and work
toward the top, cutting branches and limbs. Remove small limbs with one cut.
SKeep the tree between you and the chain. Cut from the side of the tree opposite the
branch you are cutting.
SRemove larger, supporting branches with the cutting techniques described in BUCK-
ING WITHOUT A SUPPORT.
S Always use an overcut to cut small and freely hanging limbs. Undercutting could cause limbs to fall and pinch the 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 truck of the tree.
