McCulloch MT265 CPS Spare Parts List

To start the trimmer, ensure the choke is in the closed position, press the primer bulb several times until it fills with fuel, set the throttle to the start position, and pull the starter rope firmly until the engine fires.
Use a 40:1 fuel-to-oil ratio. This means mixing 3.2 ounces of 2-stroke oil with one gallon of unleaded gasoline.
First, turn off the trimmer and disconnect the spark plug. Remove the spool from the trimmer head, wind new line onto the spool in the direction indicated, and reattach the spool to the trimmer head.
Check the fuel level, ensure the fuel is fresh, inspect the spark plug for damage, and clean the air filter. If issues persist, the carburetor may need cleaning or adjustment.
Clean the air filter after every 5 hours of use. Remove the filter, wash it in soapy water, rinse thoroughly, and allow it to dry before reinstalling.
Ensure you are using the correct diameter of trimmer line. Avoid hitting hard surfaces, and check if the line is old or brittle. Replace with new line if necessary.
Locate the adjustment screws on the carburetor. Start the engine and adjust the screws to achieve a smooth idle and proper throttle response, following the user manual for specific settings.
Regular maintenance includes cleaning the air filter, checking the spark plug, inspecting the fuel system, replacing the trimmer line, and checking for loose or damaged parts.
Empty the fuel tank, clean the trimmer thoroughly, remove the spark plug and add a few drops of oil into the cylinder, and store it in a dry place.
Check for obstructions in the trimmer head, ensure the drive shaft is engaged correctly, and inspect for wear or damage on the clutch or drive components.
