McCulloch TRIMMAC 240 Spare Parts List

To start the McCulloch TRIMMAC 240 Trimmer, ensure the trimmer is on a flat surface. Set the choke to the 'closed' position, press the primer bulb 6 times, and pull the starter handle until the engine starts. Once started, move the choke to the 'run' position.
The TRIMMAC 240 requires a mixture of unleaded gasoline and two-stroke oil in a 40:1 ratio. Ensure the fuel is fresh and properly mixed before use.
To replace the trimmer line, turn off the trimmer and disconnect the spark plug. Remove the spool cap, take out any remaining line, and insert a new line, following the directional arrows on the spool. Reattach the cap securely.
If the trimmer is not starting, check the fuel mixture, ensure the spark plug is clean and properly connected, and inspect the air filter for blockages. Replace components if necessary.
The air filter should be checked and cleaned after every 5 hours of operation. Replace it if it shows signs of damage or excessive dirt that cannot be removed by cleaning.
Regular maintenance includes checking the spark plug and air filter every 5 hours of use, inspecting the fuel filter every 25 hours, and replacing the trimmer line as needed. Lubricate the drive shaft and gearbox after every 50 hours of use.
To adjust the carburetor, locate the adjustment screws on the side of the carburetor. Use a small screwdriver to adjust the idle speed and mixture settings, following the instructions in the user manual for precise tuning.
If the trimmer line breaks frequently, ensure you are using the correct line diameter and that it is wound properly on the spool. Avoid hitting hard surfaces, as this can cause the line to snap.
For off-season storage, empty the fuel tank and run the engine until it stops. Clean the trimmer thoroughly, remove the spark plug, and apply a small amount of oil to the cylinder. Store in a dry, cool place away from direct sunlight.
Excessive vibration may be caused by an unbalanced or damaged cutting attachment. Check the attachment for wear or damage and replace if necessary. Ensure all bolts and screws are tightened properly.
