McCulloch MT325CLS Spare Parts List

To start the McCulloch MT325CLS Trimmer, ensure the trimmer is on a flat surface. Press the primer bulb 6 times, set the choke to the 'start' position, pull the starter rope until the engine fires, then set the choke to 'run' and pull the rope again to start.
The recommended fuel mix for the McCulloch MT325CLS Trimmer is a 40:1 ratio of unleaded gasoline to high-quality 2-stroke engine oil. Always mix in a clean container and shake well before use.
It is recommended to clean the air filter of the McCulloch MT325CLS Trimmer after every 5 hours of use. To clean, remove the filter cover, wash the filter in warm soapy water, rinse, and allow it to dry completely before reinstalling.
If the trimmer line won't feed, check for tangles or jams in the spool. Ensure the line is wound correctly and that it is the appropriate diameter for your trimmer. Replace if necessary. Also, make sure the bump feed mechanism is not damaged or dirty.
To replace the spark plug, disconnect the spark plug boot, use a spark plug wrench to remove the old plug, check the gap on the new spark plug, and install it by hand to avoid cross-threading. Tighten with the wrench and reattach the boot.
Overheating can be caused by a clogged air filter, incorrect fuel mixture, or blocked cooling fins. Ensure the air filter is clean, use the correct fuel mix, and clear any debris from the cooling fins to prevent overheating.
To adjust the carburetor, locate the adjustment screws labeled H (high speed) and L (low speed). With the engine running, adjust the L screw for smooth idle and the H screw for optimal performance at full throttle. Refer to the manual for exact settings.
After each use, clean the cutting attachment, inspect for damage, check the air filter, and ensure the fuel tank is empty if storing for an extended period. Regular maintenance will ensure the longevity and performance of the trimmer.
For winter storage, clean the trimmer thoroughly, drain the fuel tank, and run the engine until it stops to clear the carburetor. Remove the spark plug and add a few drops of oil into the cylinder, then pull the starter rope to distribute the oil. Store in a dry place.
Excessive vibration can be caused by a bent shaft, damaged cutting attachment, or loose parts. Inspect the shaft and attachments for any damage and ensure all parts are securely fastened. Replace any damaged components to reduce vibration.
