McCulloch MT 250 LK Spare Parts List

To start the trimmer, ensure the choke lever is in the closed position, press the primer bulb 6 times, hold the throttle trigger, and pull the starter rope until the engine fires. Move the choke to the open position and pull the rope again if necessary.
Use a 50:1 ratio of unleaded gasoline to high-quality 2-stroke engine oil. Ensure the gasoline has an octane rating of at least 89.
Turn off the trimmer and disconnect the spark plug. Remove the trimmer head cap, insert new trimmer line into the spool, wind it evenly, and reattach the cap securely.
Check the fuel level, ensure the spark plug is clean and connected, verify the air filter is not clogged, and ensure the choke lever is in the correct position.
Clean the air filter every 5 hours of operation or more frequently if used in dusty conditions. Wash it with warm soapy water and let it dry completely before reinstalling.
Use a proper screwdriver to adjust the idle speed screw. Turn it clockwise to increase the idle speed or counterclockwise to decrease it. Ensure the engine is warm before making adjustments.
Check for damaged or unbalanced cutting attachments, ensure all screws and nuts are tight, and inspect the drive shaft for damage. Replace or repair any faulty parts.
Drain the fuel tank and run the engine until it stops. Clean the unit thoroughly, inspect for damage, and store it in a dry place away from direct sunlight and moisture.
Always wear protective gear such as gloves, goggles, and hearing protection. Keep bystanders at a safe distance and avoid using the trimmer in wet or slippery conditions.
Regularly maintain the trimmer by cleaning the air filter, checking the spark plug, ensuring the correct fuel mix is used, and sharpening or replacing the cutting line as needed.
