• Keep bystanders, children, and pets at least 50 feet (15 meters) away from the operating area.
• Inspect the edger blade for damage or wear before each use. Replace damaged blades immediately.

3. Components Overview

Familiarize yourself with the main parts of your edger attachment:

• Attachment Shaft: The curved black shaft that connects to the power head.
• Edger Head: The main housing containing the blade mechanism.
• 8-inch Serrated Blade: The cutting component for edging.
• Guide Wheel: Provides stability and control during operation, and helps set cutting depth.
• Debris Flap: A rubber flap designed to protect the user from thrown debris.
• Depth Adjustment Mechanism: Allows for varying the cutting depth of the blade.

4. Setup and Assembly

This section details how to properly attach the edger to a compatible power head.

1. Ensure Power Head is Off: Before beginning, ensure your string trimmer power head is turned off and any battery packs are removed or spark plug wires disconnected for gasoline models.
2. Align Shafts: Locate the coupling on your power head and the attachment shaft of the edger. Align the arrow on the edger attachment shaft with the arrow on the power head's coupling.
3. Insert and Rotate: Push the edger attachment shaft into the power head's coupling until it clicks into place. Rotate the attachment shaft until the locking button on the power head engages with the hole on the attachment shaft.
4. Tighten Coupling: Securely tighten the coupling knob on the power head to ensure the attachment is firmly connected.
5. Verify Connection: Gently pull on the edger attachment to confirm it is securely fastened and does not wobble.

Compatibility Note: This attachment is designed for universal fit with most major brands including Ryobi, Toro, Weed Eater, Troy Bilt, Murray, and Poulan Pro trimmers.

5. Operating Instructions

Follow these steps for effective and safe operation of your edger attachment.

1. Pre-Operation Check:
   • Ensure all safety gear (eye protection, hearing protection, gloves) is worn.
   • Verify the edger attachment is securely fastened to the power head.
   • Inspect the blade for damage or excessive wear.
   • Clear the work area of any obstacles, debris, or bystanders.
2. Adjusting Cutting Depth:
   • Loosen the depth adjustment knob or lever on the edger head.
   • Raise or lower the guide wheel to achieve the desired cutting depth for the blade.
   • Tighten the depth adjustment knob or lever firmly to secure the guide wheel in position. Ensure the guide wheel can still rotate freely after tightening.
3. Starting the Edger:
   • Place the edger blade slightly above the area to be edged.
   • Start the power head according to its manufacturer's instructions. Allow the blade to reach full speed before engaging the ground.
4. Edging Technique:
   • Guide the edger along the desired edge, keeping the guide wheel on the paved surface or firm ground.
   • Maintain a steady, controlled pace. Do not force the edger.
   • Overlap passes slightly to ensure a clean, continuous edge.
   • The rubber flap is designed to protect against debris; however, always be aware of the direction of thrown material.
5. Stopping the Edger:
   • Release the trigger or turn off the power head.
   • Wait for the blade to come to a complete stop before setting the unit down or performing any adjustments.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your edger attachment.

• Cleaning: After each use, disconnect the power head and clean any grass, dirt, or debris from the edger head, blade, and guide wheel. Use a stiff brush or cloth. Do not use water directly on electrical components.
• Blade Inspection and Reversal:
  • Periodically inspect the 8-inch serrated blade for wear, nicks, or damage.
  • When one side of the blade becomes dull, the blade can be reversed to utilize the fresh cutting edges on the other side.
  • To reverse or replace the blade, ensure the power head is off and disconnected. Use appropriate tools to loosen the blade retaining nut, carefully remove the blade, flip it or replace it, and then re-secure the nut firmly. Refer to your power head's manual for specific blade removal instructions if necessary.
• Storage: Store the edger attachment in a clean, dry place, away from children and direct sunlight.
