4. Installation Instructions

This section outlines the general procedure for replacing a string trimmer head assembly. Specific steps may vary slightly depending on your trimmer model. Always refer to your trimmer's owner's manual for detailed instructions.

1. Prepare the Trimmer: Ensure the trimmer is turned off, the spark plug wire is disconnected (for gas models), or the battery is removed (for electric models). Place the trimmer on a stable, flat surface.
2. Remove Old Head (if applicable): Locate the locking mechanism or bolt that secures the existing trimmer head. This often involves inserting a small rod or screwdriver into a hole to lock the shaft, then unscrewing the head. Turn the old head counter-clockwise to loosen and remove it. Some models may require a specific wrench.
3. Clean the Shaft: Inspect the trimmer shaft for any debris, dirt, or old string fragments. Clean the area thoroughly to ensure a proper fit for the new head.
4. Install New Head: Align the new 000998265 String Trimmer Head Assembly with the trimmer shaft. Thread the new head onto the shaft by turning it clockwise until it is hand-tight. If your model requires a locking mechanism, engage it and tighten the head securely with a wrench if necessary, following your trimmer's manual for torque specifications. Do not overtighten.
5. Verify Installation: Gently tug on the installed head to ensure it is firmly attached and does not wobble.
6. Reconnect Power: Reconnect the spark plug wire or insert the battery pack.

Note: The 000998265 assembly typically includes the head and associated caps. String line is usually loaded separately into the head.

5. Operation

Once the new string head assembly is installed, refer to your trimmer's original owner's manual for instructions on loading string line and operating the trimmer safely and effectively.

• Ensure the string line is properly loaded and extends to the correct length before starting the trimmer.
• Always maintain a safe operating distance from others and objects.
• Follow all safety guidelines provided with your trimmer.

6. Maintenance

Regular maintenance of your string trimmer head assembly can extend its lifespan and ensure optimal performance.

• Clean Regularly: After each use, clean the trimmer head to remove grass clippings, dirt, and debris. This prevents buildup that can hinder string feeding or cause imbalance.
• Inspect for Damage: Periodically inspect the head assembly for cracks, wear, or other damage. Replace the head if any significant damage is observed.
• Check String Line: Ensure the string line is of the correct diameter and type recommended for your trimmer and head assembly. Replace worn or broken line promptly.
• Lubrication: Some trimmer heads may benefit from occasional lubrication of moving parts (e.g., spring mechanisms for bump feed). Consult your trimmer's manual for specific recommendations.

7. Troubleshooting

This section addresses common issues related to the string trimmer head assembly.

7.1 String Not Feeding

• Check String Load: Ensure the string is correctly wound and not tangled inside the head.
• Verify String Diameter: Using string that is too thick or too thin can cause feeding issues. Use the recommended diameter for your trimmer.
• Clean Head: Debris or grass buildup can obstruct the feeding mechanism. Clean the head thoroughly.
• Inspect for Damage: A damaged spool or cap can prevent proper feeding. Replace if damaged.

7.2 Excessive Vibration

• Unbalanced String: Unevenly cut or loaded string can cause vibration. Ensure both ends of the string are of equal length.
• Damaged Head: A cracked or broken head assembly can lead to imbalance and vibration. Replace if damaged.
• Loose Installation: Ensure the head is securely tightened onto the trimmer shaft according to installation instructions.
