Installation & Setup

Proper installation is crucial for the safe and effective operation of your new trimmer head. Always refer to your trimmer/brushcutter's original instruction manual for specific safety precautions and detailed assembly steps.

Before You Begin:

• Ensure the trimmer/brushcutter engine is off and cool.
• Disconnect the spark plug wire to prevent accidental starting.
• Wear appropriate personal protective equipment (PPE), including gloves and eye protection.

Installation Steps:

1. Remove Old Trimmer Head: Secure the shaft to prevent rotation (often with a pin or tool through a hole). Unscrew the old trimmer head, typically by turning it clockwise (reverse thread).
2. Clean Shaft Threads: Ensure the shaft threads are clean and free of debris.
3. Select Correct Adapter: Identify and use the appropriate adapter or bolt provided with your new Speed Feed head that matches your trimmer's shaft.
4. Attach New Trimmer Head: Thread the new Speed Feed trimmer head onto the shaft. Turn counter-clockwise (standard thread) until it is securely tightened. Use a wrench if necessary, but do not overtighten.
5. Verify Security: Gently tug on the head to ensure it is firmly attached and does not wobble.

Operating Instructions

Once the trimmer head is installed, you can operate your trimmer/brushcutter as usual. The Speed Feed design simplifies line reloading.

Loading Trimmer Line:

1. Align Arrows: Align the arrows on the trimmer head with the eyelets.
2. Insert Line: Feed a new length of trimmer line (refer to your trimmer's manual for recommended diameter) through one eyelet and out the other until both ends are even.
3. Wind Line: Turn the knob or bump head in the direction indicated by the arrows to wind the line into the head. The line will automatically feed into the spool.
4. Trim Excess: Once the line is fully wound, trim any excess line to the appropriate length using the cutter on the guard.

General Operation Tips:

• Always wear appropriate safety gear, including eye protection, hearing protection, long pants, and sturdy footwear.
• Maintain a safe distance from others and objects while operating.
• Use a sweeping motion to cut grass and weeds.
• Avoid hitting hard surfaces, rocks, or metal objects, as this can damage the trimmer line and head.

Maintenance

Regular maintenance will extend the life of your trimmer head and ensure consistent performance.

After Each Use:

• Clean the Head: Remove any grass, dirt, or debris from the trimmer head. A stiff brush can be helpful.
• Inspect Line: Check the trimmer line for wear or damage. Replace if necessary.

Periodic Maintenance:

• Inspect for Damage: Periodically inspect the trimmer head for cracks, chips, or other signs of wear. Replace the head if it is significantly damaged.
• Check Adapters: Ensure all adapters and bolts are securely fastened and not stripped.
• Lubrication: Some trimmer heads may benefit from light lubrication of internal moving parts (if applicable and accessible). Refer to your trimmer's manual.
