General Safety Information

Always prioritize safety when working with power tools and their accessories. Failure to follow these instructions may result in injury or property damage.

• Disconnect Power: Always disconnect the string trimmer from its power source (unplug or remove battery) before performing any maintenance, cleaning, or installing/removing parts.
• Wear Eye Protection: Always wear appropriate eye protection, such as safety glasses or goggles, when operating or maintaining a string trimmer.
• Wear Gloves: Protective gloves are recommended when handling trimmer line and spools to prevent cuts or abrasions.
• Inspect for Damage: Before each use, inspect the trimmer head and spool for any signs of damage or wear. Replace damaged parts immediately.
• Use Correct Parts: Only use genuine BLACK+DECKER replacement parts, such as the DF-080 spool, to ensure proper fit and performance.

Setup: Spool Installation

Follow these steps to correctly install the BLACK+DECKER DF-080 replacement spool into your compatible string trimmer.

1. Disconnect Power Source: Ensure the string trimmer is unplugged from the electrical outlet or the battery pack is removed.
2. Release Cover: Locate and release the tabs on the trimmer head cover (often referred to as the spool cap). Gently remove the cover.
3. Clear Debris and Remove Old Spool: Carefully remove any broken line, dirt, or debris from the trimmer head area. Then, lift out the old spool.
4. Prepare New Spool: Take the new DF-080 spool out of its packaging. Locate the two ends of the trimmer line secured in the slots on the spool. Gently pull them free. Hold the end of the line taught to prevent it from unraveling.
5. Insert Line Ends and Place Spool: Thread the ends of the new line through the eyelets in the spool hub of the trimmer head. Ensure the spool is placed onto the hub with the arrow side facing up, aligning it correctly. Approximately 5.5 inches (139.7 mm) of line should extend out of each eyelet.
6. Secure Spool: Press the spool down firmly and rotate it until it drops securely into place. When correctly seated, the spool should turn a few degrees left and right freely.
7. Snap Cap and Test: Snap the spool cap back into place, ensuring it is fully secured. Hold the tool with the cutting head facing down. Connect the power source (plug in or insert battery) and turn the tool on briefly. The nylon line should automatically cut to the proper length.

Operating Instructions

The DF-080 spool is designed for BLACK+DECKER auto-feed string trimmers, utilizing centrifugal force to automatically advance the cutting line as needed. Proper operation ensures efficient trimming and extends the life of the line.

• Automatic Line Feed: Your trimmer's auto-feed mechanism will automatically dispense more line when the existing line wears down or breaks. There is no need to manually bump the head.
• Avoid Hard Surfaces: To maximize line life and prevent premature breakage, avoid direct contact with hard surfaces such as concrete, rocks, fences, and trees. Trim around these objects carefully.
• Optimal Cutting Technique: Use the tip of the line to cut. Swing the trimmer in a wide, sweeping motion, allowing the line to do the work.

Maintenance

Regular maintenance of your trimmer head and spool area will ensure consistent performance.

• Clean Trimmer Head: Periodically, with the power disconnected, remove the spool cap and spool. Clean out any accumulated grass, dirt, or debris from the trimmer head housing. This prevents interference with the line feed mechanism.
• Inspect Spool and Eyelets: Check the spool for cracks or damage. Ensure the line eyelets on the trimmer head are clear and not worn excessively.
• Storage: Store replacement spools in a cool, dry place away from direct sunlight to maintain line integrity.

Troubleshooting

If you encounter issues with your trimmer line, consider the following common solutions:

• Line Not Feeding:
  • Ensure the spool is correctly seated and the cap is securely fastened.
  • Check for tangled line within the spool. If tangled, remove the spool and manually untangle the line, ensuring it is wound neatly.
  • Clean any debris from the trimmer head that might be obstructing the line feed mechanism.
• Line Breaking Frequently:
  • Review operating technique to avoid hitting hard surfaces.
  • Ensure the line is not old or brittle. Store spools in a cool, dry environment.
  • Verify that the trimmer's cutting blade (if present) is clean and sharp, as a dull blade can cause line to break prematurely.
