To start the McCulloch MC125 Trimmer, ensure that the trimmer is on a flat surface. Press the primer bulb several times until fuel is visible, set the choke lever to the start position, pull the starter rope until the engine fires, then move the choke to the run position.
Use a mix of 2-cycle engine oil and unleaded gasoline with a 40:1 ratio for optimal performance. Avoid using fuel that contains more than 10% ethanol.
To replace the trimmer line, turn off the trimmer and disconnect the spark plug. Remove the spool cover, unwind the old line, and wind the new line around the spool following the arrow directions. Reattach the spool cover securely.
If the trimmer is not cutting properly, check if the trimmer line is worn or too short, and replace it if necessary. Also, ensure that the cutting head is clean and free from debris.
Regular maintenance should be performed after every 5 hours of use. This includes cleaning the air filter, checking the spark plug, and ensuring that the trimmer line is in good condition.
If the engine is overheating, turn off the trimmer and allow it to cool. Check for any blockages in the air intake and exhaust areas. Ensure that the cooling fins are clean and not obstructed.
For off-season storage, empty the fuel tank and run the engine until it stops. Clean the trimmer thoroughly, and store it in a dry place away from direct sunlight.
To prevent the line from breaking, avoid contact with hard surfaces like walls and fences. Use the correct type and diameter of line recommended for the MC125 model.
If the trimmer won't start, check the fuel level and ensure fresh fuel is used. Inspect the spark plug for wear or damage, and clean or replace it if necessary. Verify that the air filter is clean.
