Important Safety Information
Always prioritize safety when working with power tools. Adhere to the following guidelines:
- Always wear safety glasses to protect your eyes from debris.
- Wear long pants and sturdy shoes for personal protection.
- Ensure bystanders are kept away from the operating area while the trimmer is in use.
- Before performing any maintenance or changing parts, ensure the trimmer's power source (battery) is disconnected.
Setup: Spool and Cap Installation
Follow these steps to replace the string trimmer spool and cap:
- Disconnect Power: Before beginning, ensure your string trimmer is turned off and the battery pack is removed to prevent accidental startup.
- Remove Old Spool and Cap: Press the tabs on the side of the existing cap cover and pull it off. Carefully remove the old spool from the trimmer head.
- Prepare New Spool: Take a new Generep replacement spool. Locate the small hole on the spool and insert the end of the trimmer line into it.
- Insert New Spool: Align the new spool with the trimmer head. Ensure the line is threaded through the eyelet on the trimmer head. The automatic winding feature allows for quick changes.
- Attach New Cap Cover: Place the new cap cover over the spool, aligning the tabs with the slots on the trimmer head. Press firmly until it clicks into place, securing the spool.
- Verify Installation: Gently pull on the trimmer line to ensure it is properly seated and can feed freely.

Operating Guidelines
Once the new spool and cap are installed, you can resume using your string trimmer. The 0.065-inch high-strength copolymer nylon resin line is designed for effective cutting and durability. For best results, operate your trimmer according to its original manufacturer's instructions.

Maintenance
Proper maintenance ensures the longevity of your replacement spools and cap:
- Storage: Store unused spools in a cool, dry place away from direct sunlight to prevent the line from becoming brittle.
- Cleaning: Periodically clean the trimmer head and cap cover to remove accumulated grass and debris, which can impede line feeding.
- Inspection: Before each use, inspect the trimmer line for any signs of wear, fraying, or damage. Replace the spool if the line appears compromised.
Troubleshooting
Refer to the table below for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Trimmer line not feeding automatically. | Line is tangled or stuck inside the spool; debris in the trimmer head; incorrect spool installation. | Remove the cap and spool, untangle the line, clear any debris, and re-install the spool ensuring the line is properly threaded. |
| Line breaks frequently. | Line is worn, old, or brittle; hitting hard surfaces; incorrect trimming technique. | Replace with a new spool. Avoid hitting concrete, rocks, or fences. Use a sweeping motion to trim. |
| Cap cover does not fit securely. | Incorrect cap model; debris preventing proper seating; tabs are damaged. | Ensure you are using the correct cap model for your trimmer. Clean the area where the cap seats. Inspect tabs for damage. |
