Setup and Installation

The P25 trimmer head is designed for easy installation on a wide range of petrol grass trimmers. It comes with five different adaptors to ensure compatibility.

1. Identify the correct adaptor: Consult your trimmer's instruction manual to determine the correct mounting thread size and type for your specific model. Select the adaptor from the provided set that matches your trimmer's shaft.
2. Prepare the trimmer: Ensure the trimmer is turned off and cooled down. Disconnect the spark plug wire for safety.
3. Remove existing head (if applicable): If an old trimmer head is present, remove it according to your trimmer's manual.
4. Install the adaptor: Screw the selected adaptor onto the trimmer's drive shaft. Ensure it is securely tightened.
5. Attach the P25 trimmer head: Align the P25 trimmer head with the installed adaptor and screw it on until it is firmly seated. Do not overtighten.
6. Verify installation: Gently tug on the trimmer head to ensure it is securely attached and does not wobble.

Operating Instructions

The McCulloch Universal Trimmer Head P25 is designed for efficient cutting of short to medium length grass and light bushes.

• Starting the Trimmer: Follow your trimmer's manufacturer instructions for starting the engine.
• Trimming Technique: Hold the trimmer firmly with both hands. Use a sweeping motion to cut grass. Avoid hitting hard objects like rocks, fences, or concrete, as this can damage the line and the trimmer head.
• Line Advancement: The P25 features an automatic line advancement system. When the line wears down, simply tap the trimmer head lightly on the ground while the engine is running at operating speed. This will release a small amount of new line. The cutting blade on your trimmer's guard will automatically trim the line to the correct length.
• Optimal Performance: For best results, maintain a consistent engine speed and avoid overloading the trimmer head by trying to cut too much material at once.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your trimmer head.

• Cleaning: After each use, clean the trimmer head to remove grass clippings, dirt, and debris. Use a brush or cloth. Do not use harsh chemicals.
• Line Replacement: When the pre-loaded line is depleted, replace it with a new spool of 2.0 mm trimmer line, such as the McCulloch SPO001 replacement spool.
• Replacing the Spool:
  1. Ensure the trimmer is off and the spark plug wire is disconnected.
  2. Locate the tabs or buttons on the side of the trimmer head. Press them in and pull the cap off.
  3. Remove the empty spool.
  4. Insert the new pre-wound spool, ensuring the line ends are threaded through the eyelets on the trimmer head casing.
  5. Replace the cap, ensuring it clicks securely into place.
• Storage: Store the trimmer head in a clean, dry place, away from direct sunlight and extreme temperatures.
