Tree Felling Techniques, Felling Large Trees

SKeep the engine at full speed the entire time you are cutting.

SAllow the chain to cut for you. Exert only light downward pressure.

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, unneces- sary wear can occur.

STo avoid losing control when cut is com- plete, do not put pressure on saw at end of cut.

SStop the engine before setting the saw down.

TREE FELLING TECHNIQUES

WARNING: Felling a tree requires chain saw skills and experience. Inexperi- enced users should not fell trees. Do not at- tempt any task that makes you feel uncom- fortable or unsure.

WARNING: Do not cut near buildings or electrical wires if you do not know the di- rection of tree fall, at night since you will not be able to see well, or during bad weather such as rain, snow, or strong winds. as fall is unpredictable.

Carefully plan your sawing operation in ad- vance. You need a clear area all around the tree so you can have secure footing. Check for broken or dead branches which can fall on you causing serious injury.

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. 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, staples, and wire from the tree where cuts are to be made.

Plan a clear retreat path

FELLING LARGE TREES

(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.

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.

Second cut

S After removing the wood from the notch, make the felling cut on the opposite side of the notch. This is done by making a cut about 5 cm 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 fall- ing in the wrong direction.

Hinge holds tree on stump and helps control fall

Opening of felling cut

Closing of notch

NOTE: Before felling cut is complete, use wedges to open the cut when necessary to control the direction of fall. To avoid kickback or 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 felling 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 par- tially fallen trees that may be poorly sup- ported. When a tree doesn’t fall completely, set the saw aside and pull down the tree with a cable winch, block and tackle, or tractor.

CUTTING A FALLEN TREE

(BUCKING)

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

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.

Aug-42 specifications

The McCulloch Aug-42 is a remarkable piece of engineering that showcases innovation in the small engine and handheld power tool industry. This chainsaw, introduced by McCulloch, has made its mark for its reliability, efficiency, and ease of use, making it an excellent choice for both professional and amateur users.

At the heart of the Aug-42 is a powerful 42cc engine that provides optimal performance for cutting tasks. The engine's design emphasizes lightweight construction while maintaining durability, allowing for ease of maneuverability. This is especially beneficial for users who may be involved in lengthy cutting or trimming tasks, as the lightweight build reduces fatigue.

One of the standout features of the Aug-42 is its anti-vibration technology. This innovation significantly minimizes the vibrations felt by the user during operation, enhancing comfort and control. As a result, operators can work for extended periods without the discomfort typically associated with prolonged chainsaw use.

The Aug-42 also incorporates a strategized fuel delivery system that maximizes power while ensuring fuel efficiency. It features a catalytic muffler that not only reduces noise during operation but also lowers the emissions produced, making it a more environmentally responsible choice. This combination of power and eco-friendliness caters to today’s environmentally conscious consumers.

The chainsaw comes equipped with a side-access chain tensioning system. This allows users to adjust the chain tension without needing to remove the guide bar, resulting in quick and hassle-free adjustments in the field. This essential feature minimizes downtime and keeps the user focused on their task.

Safety is another priority in the design of the McCulloch Aug-42. It includes an automatic chain brake that halts the chain’s motion when unexpected movements occur, protecting the user from possible accidents. Additionally, the chainsaw has a comfortable grip handle designed to provide optimum control, even in wet conditions.

In summary, the McCulloch Aug-42 fuses power, efficiency, and safety into a robust, user-friendly package. Its advanced technologies, including anti-vibration systems, fuel efficiency features, and safety mechanisms, position it as a preferred choice for those needing a dependable chainsaw. Whether used for general yard work, tree trimming, or more significant outdoor projects, the Aug-42 stands as a testament to McCulloch’s commitment to quality and innovation in outdoor power equipment.
