caution when cutting small size limbs.
Slender material may catch the saw chain
and be whipped toward you or pull you off
balance.

branches that are bent or under pressure.
Avoid being struck by the branch or the
saw when the tension h_the wood fibers is
released.
• Keep a clear work area. Frequently clear
branches out of the way to avoid tripping
over them.
LIMBING
• Always limb a tree after it is cut down. Only
then can limbing be done safely and prop-
erly.
• Leave the larger limbs underneath the
felled tree to support the tree as you work.
• Start at the base of the feIled tree and work
toward the top. cutting branches and
limbs. Remove small limbs with one cut.
• Keep the tree between you and the chain.
Cut from the side of the tree opposite the
branch you are cutting,
• Remove larger, supporting branches with
the cutting techniques described in BUCK-
ING WITHOUT A SUPPORT.
• Always use an overcut to cut small and
freely hanging limbs. Undercutting could
cause limbs to fall and pinch the saw.

shoulder height or below, Do not cut if
branches are higher than your shoulder. Get
