To start the McCulloch Tri Mac 210, ensure the trimmer is on a flat surface. Set the choke to the 'closed' position, press the primer bulb 6 times, hold the throttle trigger, and pull the starter rope until the engine fires. Then, set the choke to 'open'.
The recommended fuel mixture for the McCulloch Tri Mac 210 is 40:1, which means you should mix 3.2 ounces of 2-stroke oil with 1 gallon of unleaded gasoline.
To replace the trimmer line, first remove the trimmer head by unscrewing it. Cut a 6-meter length of 2mm line, thread it through the center, and wind it evenly on both sides of the spool. Reattach the spool to the trimmer head.
If the trimmer won't start, check the fuel mixture, ensure the spark plug is clean and properly connected, and inspect the air filter for dirt. If issues persist, consider having a professional examine the carburetor.
It's recommended to clean the air filter after every 5 hours of operation or more frequently if used in dusty conditions. Remove the air filter, wash it with soap and water, let it dry, and apply a small amount of oil before reinstalling.
Frequent line breakage can result from using the wrong type of line, overloading the trimmer, or hitting hard surfaces. Ensure you are using the correct line diameter and avoid contact with concrete or rocks.
For winter storage, empty the fuel tank, run the engine until it stops to clear the carburetor, clean the unit thoroughly, and store it in a dry, dust-free environment. Consider removing the spark plug and adding a few drops of oil into the cylinder for protection.
Excessive vibration may be caused by an unbalanced trimmer head or damaged parts. Check for debris in the head, ensure the line is evenly wound, and inspect for worn or broken components that might need replacement.
To adjust the carburetor, locate the adjustment screws on the side. Turn the 'L' screw for low speed and 'H' screw for high speed adjustments. Adjust each screw by a quarter turn, testing the trimmer after each adjustment until optimal performance is achieved.
Regular maintenance includes checking and cleaning the air filter, inspecting and replacing the spark plug as needed, cleaning the trimmer head, and ensuring the fuel system is free of old fuel. Regular lubrication of moving parts is also recommended.
