CHAIN TENSION (Including units with chain already installed)

WARNING: Wear protective gloves when handling chain. The chain is sharp and can cut you even when it is not moving.

NOTE: When adjusting chain tension, make sure the bar knob is finger tight only. Attempting to tension the chain when the bar knob is tight can cause damage.

Checking the tension:

Use the screwdriver end of the chain adjust- ment tool (bar tool) to move chain around guide bar. If the chain does not rotate, it is too tight. If the chain is too loose, it will sag below the bar.

Adjusting the tension:

Chain tension is very important. Chains stretch during use. This is especially true during the first few times you use your saw. Always check chain tension each time you use and refuel your saw.

WARNING: Failure to push lever on bar knob down to closed/locked position could result in serious personal injury or damage to your chain saw.

6.Use the screwdriver end of the chain ad- justment tool (bar tool) to move chain around guide bar.

7.If chain does not rotate, it is too tight. Loosen bar knob 1 turn (counterclock- wise); then, loosen chain by turning the adjusting wheel 1/4 turn (upward direc- tion). Retighten bar knob.

8.If chain is too loose, it will sag below the guide bar. DO NOT operate the saw if the chain is loose.

WARNING: If the saw is operated with a loose chain, the chain could jump off the guide bar and result in serious injury.

WARNING: Muffler is very hot during and after use. Do not touch the muffler or al- low combustible material such as dry grass or fuel to do so.

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.
