Opening of felling cut

SThe wind direction and speed.

S The lean of the tree. The lean of a tree might not be apparent due to uneven or sloping terrain. Use a plumb or level to de- termine the direction of tree lean.

SWeight and branches on one side. S Surrounding trees and obstacles.

Look for decay and rot. If the trunk is rotted, it can snap and fall toward the operator. Check for broken or dead branches which can fall on you while cutting.

Make sure there is enough room for the tree to fall. Maintain a distance of 2-1/2tree lengths from the nearest person or other objects. En- gine noise can drown out a warning call.

Remove dirt, stones, loose bark, nails, sta- ples, and wire from the tree where cuts are to be made. Plan a clear retreat path to the rear and diagonal to the line of fall.

FELLING LARGE TREES

(6 inches (15 cm) in diameter or larger) The notch method is used to fell large trees. A notch is cut on the side of the tree in the de- sired direction of fall. After a felling cut is made on the opposite side of tree, the tree will tend to fall into the notch.

NOTE: If the tree has large buttress roots, remove them before making the notch. If us- ing saw to remove buttress roots, keep saw chain from contacting ground to prevent dull- ing of the chain.

NOTCH CUT AND FELLING THE TREE

SMake notch cut by cutting the top of the notch first. Cut through 1/3 of the diameter of the tree. Next complete the notch by cut- ting the bottom of the notch. See illustra- tion. Once the notch is cut remove the notch of wood from the tree.

the notch. This will leave enough uncut wood between the felling cut and the notch to form a hinge. This hinge will help prevent the tree from falling in the wrong direction.

Closing of notch

NOTE: Before felling cut is complete, use wedges to open the cut if necessary to control the direction of fall. To avoid kickback and chain damage, use wood or plastic wedges, but never steel or iron wedges.

SBe alert to signs that the tree is ready to fall: cracking sounds, widening of the fell- ing cut, or movement in the upper

branches.

SAs tree starts to fall, stop saw, put it down, and get away quickly on your planned re-

treat path.

SDO NOT cut down a partially fallen tree with your saw. Be extremely cautious with partially fallen trees that may be poorly supported. When a tree doesn’t fall com- pletely, set the saw aside and pull down the tree with a cable winch, block and tackle, or tractor.

(BUCKING)

Bucking is the term used for cutting a fallen tree to the desired log size.

WARNING: Do not stand on the log being cut. Any portion can roll causing loss of footing and control. Do not stand downhill of the log being cut.

IMPORTANT POINTS

SCut only one log at a time.

S Cut shattered wood very carefully; sharp pieces of wood could be flung toward opera- tor.

S Use a sawhorse to cut small logs. Never
