Setup and Installation
Before installing the new spool, ensure your MacAllister MGT600 grass trimmer is switched off and disconnected from its power source to prevent accidental operation. Always wear appropriate safety gear, including gloves and eye protection, during installation.
- Remove the Trimmer Head Cap: Locate the trimmer head at the bottom of your grass trimmer. Depending on your model, you may need to press release tabs or twist the cap counter-clockwise to remove it.
- Remove the Old Spool: Carefully lift out the old or empty spool from the trimmer head. Dispose of the old spool and any remaining line responsibly.
- Prepare the New Spool: The ALM FL289 spool comes pre-wound with two lines. Ensure the ends of both lines are free and can be fed through the eyelets of the trimmer head.

- Insert the New Spool: Align the new ALM FL289 spool with the housing in the trimmer head. Ensure the spool sits correctly and the line ends are threaded through the designated eyelets on the trimmer head.

- Replace the Trimmer Head Cap: Once the spool is correctly seated and the lines are threaded, replace the trimmer head cap. Ensure it clicks into place or is securely twisted to prevent it from detaching during operation.
- Check Line Length: Trim any excess line extending from the eyelets to the recommended length for your trimmer model, typically using the built-in line cutter on the guard.
Operating Instructions
The ALM FL289 spool and line are designed for automatic line feeding systems found in compatible MacAllister MGT600 grass trimmers.
- Automatic Line Feed: During operation, the trimmer's automatic feed mechanism will dispense new line as needed when the existing line wears down or breaks. This typically occurs by tapping the trimmer head on the ground while the motor is running. Refer to your grass trimmer's main instruction manual for specific line feeding procedures.
- Line Management: The spool is designed to manage two lines simultaneously, providing efficient cutting performance.
Maintenance
Proper maintenance ensures the longevity and performance of your ALM spool and line.
- Storage: Store unused spools in a cool, dry place away from direct sunlight and extreme temperatures. This helps prevent the trimmer line from becoming brittle.
- Inspection: Before each use, inspect the line for any signs of wear, fraying, or damage. Replace the spool if the line is severely damaged or if the spool itself is cracked.
- Cleaning: Periodically clean the trimmer head area to remove any accumulated grass clippings or debris that might impede line feeding.
Troubleshooting
If you encounter issues with your ALM spool and line, consider the following:
- Line Not Feeding:
- Ensure the spool is correctly seated in the trimmer head.
- Check for tangled or crossed lines on the spool.
- Verify that the line is not jammed in the eyelets.
- The line might be fused together due to heat; try unwinding a small section and re-feeding.
- Line Breaking Frequently:
- The line may be old or brittle. Ensure proper storage.
- You might be cutting against hard surfaces (e.g., concrete, rocks).
- The line diameter (1.5mm) is specific; ensure it's suitable for your trimmer's power.
- Spool Does Not Fit:
- Confirm your trimmer model is MacAllister MGT600. This spool (FL289) is specifically designed for this model.
- Double-check the orientation of the spool during installation.
