6. Installation Instructions

Follow these steps carefully to install the new trimmer head.

1. Prepare the Trimmer: Ensure the string trimmer is turned off, the engine is cool, and the spark plug wire is disconnected (or battery removed for electric models) to prevent accidental starting.
2. Remove Old Trimmer Head:
   • Locate the locking hole on the trimmer's gear case or shaft. Insert a small screwdriver or pin into this hole to lock the shaft.
   • Rotate the old trimmer head counter-clockwise (for most models, it's left-hand thread) to loosen and remove it. Some models may require a wrench.
3. Select Correct Adapter: Identify the correct thread adapter from the included set that matches your trimmer's shaft. The adapters come in various sizes and thread directions (right-hand or left-hand). Refer to your trimmer's manual if unsure.
4. Install Adapter (if needed): If your trimmer requires an adapter, screw it onto the trimmer shaft. Ensure it is snug.
5. Install New Trimmer Head:
   • Align the new Ewon P25 P35 Trimmer Head with the shaft or the installed adapter.
   • Rotate the trimmer head clockwise (for left-hand thread) or counter-clockwise (for right-hand thread) until it is securely tightened. Continue to hold the shaft locked with the pin.
   • Remove the locking pin.
6. Verify Installation: Gently tug on the trimmer head to ensure it is firmly attached and does not wobble.

7. Operating Instructions

This trimmer head features a bump-feed mechanism for line advancement.

1. Starting the Trimmer: Follow your string trimmer's manufacturer instructions to start the engine/motor.
2. Advancing Trimmer Line:
   • While the trimmer head is spinning at full speed, gently tap the bottom of the trimmer head on a firm, non-abrasive surface (e.g., grass, dirt).
   • The impact will release a small amount of line from the spool.
   • The line cutting blade on your trimmer's guard will automatically trim the line to the correct length.
3. Cutting Technique: Maintain a safe distance from objects and bystanders. Use a sweeping motion to cut grass and weeds. Avoid hitting hard surfaces like concrete or rocks, as this can damage the line and the trimmer head.

8. Maintenance

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

• Cleaning: After each use, clean the trimmer head to remove grass clippings, dirt, and debris. Use a stiff brush or cloth. Do not use harsh chemicals.
• Line Replacement: When the trimmer line runs out or becomes too short, it needs to be replaced.
  1. Ensure the trimmer is off and disconnected from power.
  2. Press the tabs on the side of the trimmer head cover and remove the cover.
  3. Remove the old spool.
  4. Take the new trimmer line (or rewind the existing spool with new line, ensuring it's wound tightly and evenly in the direction indicated on the spool).
  5. Feed the ends of the line through the eyelets on the trimmer head housing.
  6. Place the spool back into the housing, ensuring it seats correctly.
  7. Reattach the cover, ensuring it clicks securely into place.
• Inspect for Damage: Periodically inspect the trimmer head for cracks, excessive wear, or damage to the eyelets. Replace the head if significant damage is found.
