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.

S Leave the larger limbs underneath the felled tree to support the tree as you work.

SStart at base of the felled tree and work to-

ward the top, cutting branches and limbs. Remove small limbs with one cut.

SKeep the tree between you and the chain

as much as possible.

SRemove larger, supporting branches with the cutting techniques described in BUCK-

ING WITHOUT A SUPPORT.

SAlways use an overcut to cut small and freely hanging limbs. Undercutting could cause limbs to fall and pinch saw.

PRUNING

WARNING: Limit pruning to limbs shoulder height or below. Do not cut if branches are higher than your shoulder. Get a professional to do the job.

SMake your fist cut 1/3 of the way through

the bottom of the limb.

SNext make a 2nd cut all the way through the limb. Then cut a third overcut leaving a 3 to 5 cm collar from the trunk of the tree.

Cleaning the air filter:

A dirty air filter decreases engine perform- ance and increases fuel consumption and harmful emissions. Always clean after every 5 hours of operation.

1.Clean the cover and the area around it to keep dirt and sawdust from falling into the carburetor chamber when the cover is removed.

2.Remove the parts as illustrated.

3.Wash the filter in soap and water. Rinse in clean cool water. Air dry completely before reinstalling.

BAR MAINTENANCE

If your saw cuts to one side, has to be forced through the cut, or been run with an improper amount of bar lubrication it may be neces- sary to service your bar. A worn bar will dam- age your chain and make cutting difficult.

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.
