To start the McCulloch B28B Trimmer, first ensure the trimmer is on a flat surface. Set the choke lever to the "Start" position, press the primer bulb 6 times, and pull the starter handle until the engine fires. Then, move the choke to the "Run" position.
Use unleaded gasoline with a minimum octane rating of 90, mixed with high-quality 2-stroke engine oil at a ratio of 40:1 for optimal performance.
Clean the air filter after every 5 hours of operation to ensure optimal engine performance and longevity.
If the trimmer line is not feeding properly, check for any tangles or jams in the spool. Ensure the line is wound correctly and that the spool is not damaged.
To replace the trimmer line, remove the spool cap, take out the old line, and insert a new line of the appropriate diameter. Follow the direction indicated on the spool for winding the line.
Common causes of engine stalling include a clogged air filter, incorrect fuel mixture, or a dirty spark plug. Check and clean each component as needed.
Ensure that the air vents are clean and free of debris, use the correct fuel mixture, and avoid running the trimmer at full throttle for extended periods.
After use, clean the trimmer thoroughly to remove grass and debris, inspect the trimmer line and replace if necessary, and check the fuel and oil levels for the next use.
If the trimmer won't start, check the fuel level and quality, examine the spark plug for wear or fouling, and ensure the air filter is clean.
Wear appropriate personal protective equipment such as gloves, eye protection, and sturdy footwear. Keep bystanders at a safe distance and operate the trimmer according to the manual's instructions.
