Safety Information
Always prioritize safety when working with power tools. While the TR255 is a consumable part, its installation and use are directly related to the operation of a trimmer or brushcutter. Adhere to the safety guidelines provided with your power tool.
- Eye Protection: Always wear safety glasses or goggles when operating a trimmer or brushcutter.
- Hand Protection: Wear sturdy gloves to protect your hands during installation and operation.
- Foot Protection: Wear appropriate footwear, such as work boots, to prevent injury.
- Hearing Protection: Use ear defenders or earplugs to protect against noise-induced hearing loss.
- Power Disconnection: Ensure the trimmer/brushcutter is turned off and disconnected from its power source (unplugged or battery removed) before attempting any installation, maintenance, or line replacement.
- Clear Area: Ensure the work area is clear of bystanders, pets, and debris before starting the trimmer.
- Inspect Equipment: Before each use, inspect the trimmer head and line for any damage or wear. Replace worn parts immediately.
Setup and Installation
The ALM TR255 is a pre-wound spool designed for easy replacement in compatible trimmer heads. Follow these general steps for installation. Refer to your trimmer's specific user manual for detailed instructions on accessing and replacing the spool.
- Prepare the Trimmer: Ensure the trimmer is turned off and disconnected from its power source.
- Access the Trimmer Head: Depending on your trimmer model, you may need to press tabs, twist, or unscrew parts of the trimmer head cover to expose the old spool.
- Remove Old Spool: Carefully remove the old, empty, or damaged line spool from the trimmer head.
- Insert New Spool: Place the new ALM TR255 spool into the trimmer head, ensuring the line ends are threaded through the eyelets on the trimmer head cover. Make sure the spool is seated correctly and securely.
- Reassemble Trimmer Head: Reattach the trimmer head cover, ensuring it clicks into place or is securely screwed back on.
- Check Line Length: Trim any excess line if it is too long, ensuring it does not exceed the cutting guard's limits.

Operating Instructions
The TR255 spool functions as the cutting component of your trimmer. Once installed, operate your trimmer according to its manufacturer's instructions. The line will automatically feed or can be manually advanced depending on your trimmer's design.
- Line Feeding: Most trimmers with this type of spool feature an automatic or bump-feed mechanism. Lightly tap the trimmer head on the ground while the motor is running to advance the line.
- Optimal Cutting: For best results, cut with the tip of the line. Avoid forcing the line into thick brush, as this can cause premature wear or breakage.
- Line Wear: The trimmer line will naturally wear down during use. Replace the spool when the line is depleted or if it becomes damaged beyond effective use.
Maintenance
Proper maintenance of your trimmer head and line spool ensures optimal performance and longevity.
- Clean Trimmer Head: Regularly clean grass and debris from the trimmer head, especially around the spool area, to prevent buildup that can impede line feeding.
- Store Properly: Store spare TR255 spools in a cool, dry place away from direct sunlight. Extreme temperatures can affect the line's flexibility and durability.
- Inspect for Damage: Before each use, inspect the spool and line for any cracks, fraying, or other signs of damage. Replace if necessary.
Troubleshooting
If you encounter issues with your trimmer line, consider the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Line not feeding | Tangled line, debris in head, incorrect spool installation, worn line. | Remove spool, untangle line, clean trimmer head, re-install spool correctly. Replace spool if line is too worn. |
| Line breaks frequently | Cutting against hard surfaces, old/brittle line, incorrect line diameter for trimmer, excessive force. | Avoid hitting hard objects. Ensure line is fresh. Use appropriate line for your trimmer. Reduce cutting force. |
| Trimmer head vibrates excessively | Improperly seated spool, damaged trimmer head. | Re-seat the spool. Inspect trimmer head for damage and replace if necessary. |
