OPERATING YOUR UNIT

BEFORE STARTING ENGINE

WARNING: Be sure to read the fuel information in the safety rules before you be- gin. If you do not understand the safety rules, do not attempt to fuel your unit. Contact an authorized service dealer.

BAR AND CHAIN LUBRICATION

The bar and chain require continuous lubri- cation. Lubrication is provided by the auto- matic oiler system when the oil tank is kept filled. Lack of oil will quickly ruin the bar and chain. Too little oil will cause overheating shown by smoke coming from the chain and/ or discoloration of the bar. Only use Bar and Chain Oil for bar and chain lubrication.

FUELING ENGINE

WARNING: Remove fuel cap slowly when refueling.

This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality 2-cycle air-cooled engine oil designed to be mixed at a ratio of 40:1. A 40:1 ratio is obtained by mixing 0,125 liter of oil with 5 liters of unleaded gasoline. DO NOT USE automotive or boat oil. These oils will cause engine damage. When mixing fuel follow the instructions printed on the container. Always read and follow the safety rules relating to fuel before fueling your unit.

IMPORTANT

Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, empty the fuel system before storage for 30 days or longer. Drain the gas tank, start the en- gine and let it run until the fuel lines and carbu- retor are empty. Use fresh fuel next season. Never use engine or carburetor cleaner prod- ucts in the fuel tank or permanent damage may occur.

CHAIN BRAKE

Ensure chain brake is disengaged by pulling the front hand guard back toward the front han- dle as far as possible. The chain brake must be disengaged before cutting with the saw.

WARNING: The chain must not move when the engine runs at idle speed. If the chain moves at idle speed refer to CAR- BURETOR ADJUSTMENT within this manual. Avoid contact with the muffler. A hot muffler can cause serious burns.

To stop the engine, move the ON/STOP switch to the STOP position.

To start the engine, hold the saw firmly on the ground as illustrated below. Make sure the chain is free to turn without contacting any object.

Use only 40 --- 45 cm of rope per pull.

Hold saw firmly while pulling starter rope. Starter Rope Handle

Left Hand on Front Handle

Right Foot Through Rear Handle

IMPORTANT POINTS TO REMEMBER

When pulling the starter rope, do not use the full extent of the rope as this can cause the rope to break. Do not let starter rope snap back. Hold the handle and let the rope rewind slowly.

For cold weather starting, start the unit at full choke; allow the engine to warm up before squeezing the throttle trigger.

NOTE: Do not cut material with the choke/fast idle lever at the FULL CHOKE position.

STARTING A COLD ENGINE (or a warm engine after running out of fuel)

NOTE: In the following steps, when the cho- ke/fast idle lever is pulled out to the full ex- tent, the correct throttle setting for starting is set automatically.

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.
