ing your saw before you begin a major sawing operation.

SSqueeze the throttle trigger and allow the engine to reach full speed before

cutting.

SBegin cutting with the saw frame against the log.

SKeep the engine at full speed the en-

tire time you are cutting.

SAllow the chain to cut for you. Exert only light downward pressure. If you force the cut, damage to the bar,

chain, or engine can result.

SRelease the throttle trigger as soon as the cut is completed, allowing the en- gine to idle. If you run the saw at full throttle without a cutting load, unnec- essary wear can occur to the chain, bar, and engine. It is recommended that the engine not be operated for longer than 30 seconds at full

throttle.

STo avoid losing control when cut is

complete, do not put pressure on saw at end of cut.

S Stop the engine before setting the saw down after cutting.

TREE FELLING TECHNIQUES

WARNING: Check for broken or dead branches which can fall while cutting causing serious injury. Do not cut near build- ings or electrical wires if you do not know the direction of tree fall, nor cut at night since you will not be ale to see well, nor during bad weather such as rain, snow, or strong winds, etc.

SCarefully plan your sawing operation in ad- vance.

SClear the work area. You need a clear area all around the tree so you can have secure

footing.

S Study the natural conditions that can cause the tree to fall in a particular direc- tion.

Natural conditions that can cause a tree to fall in a particular direction include:

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 ob- jects. Engine 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 diag- onal to the line of fall.

FELLING LARGE TREES

(6 inches 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 using saw to remove buttress roots, keep saw chain from contacting ground to pre- vent dulling of the chain.

NOTCH CUT AND FELLING THE TREE

S Make 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 illus- trated. Once the notch is cut remove the notch of wood from the tree.

SAfter removing the cutout of wood, make the felling cut on the opposite side of the notch. This is done by making a cut about two inches higher than the center of 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.

Final (felling) cut here. 2 inches above center of notch.
