Setup:
- Safety First: Ensure the trimmer is switched off and the spark plug is disconnected to prevent accidental starting.
- Disassemble Trimmer Head: Carefully follow your STIHL trimmer's manual to disassemble the AutoCut 25-2 head and remove the old spool and worn components.
- Install New Spring: Place the new helical spring into its correct position within the trimmer head assembly.
- Install New Cap: Fit the new base cover cap over the spool and spring, ensuring it clicks or locks securely into place as per the original.
- Reassemble Head: Reassemble the rest of the trimmer head according to your STIHL manual.
- Test: Reconnect the spark plug and test the bump-feed mechanism.
Care:
- Regularly clean debris from around the trimmer head.
- Inspect the cap and spool for damage during line changes.
- Avoid excessive force when bumping the head, as this can damage components.
