McCulloch MC3516 Bucking Without a Support, Bucking Using a LOG or Support Stand, Limbing

Overcutting

Undercutting

Undercutting involves cutting on the under- side of the log with top of saw against the log. When undercutting use light upward pres- sure. Hold saw firmly and maintain control. The saw will tend to push back toward you.

WARNING: Never turn saw upside down to undercut. The saw cannot be con- trolled in this position.

Always make your first cut on the compres- sion side of the log. The compression side of the log is where the pressure of the log’s weight is concentrated.

BUCKING WITHOUT A SUPPORT

SOvercut through 1/3 of the diameter of the

log.

SRoll the log over and finish with a second overcut.

SWatch for logs with a compression side to prevent the saw from pinching. See il- lustrations for cutting logs with a compres- sion side.

BUCKING USING A LOG OR SUPPORT STAND

SRemember your first cut is always on the

compression side of the log.

(Refer to the illustrations below for your first and second cut)

LIMBING AND PRUNING

WARNING: Be alert for and guard against kickback. Do not allow the moving chain 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 ladders, plat- forms, a log, or in any position which can cause you to lose your balance or control of the saw.

IMPORTANT POINTS

S Work slowly, keeping both hands firmly gripped on the saw. Maintain secure footing and balance.

SWatch out for springpoles. Springpoles are small size limbs which can catch the saw

chain and whip toward you or pull you off bal- ance. Use extreme caution when cutting small size limbs or slender material.

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.

S Keep 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.

SLeave 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.
