4. Installation

Follow these steps to replace the spool housing on your BLACK+DECKER string trimmer:

1. Prepare the Trimmer: Ensure the trimmer is disconnected from its power source. Place the trimmer on a stable, flat surface.
2. Remove Old Spool Housing: Locate the screw that secures the existing spool housing to the trimmer shaft. Use an appropriate screwdriver to remove this screw. Gently wiggle and pull the old housing off the shaft.
3. Clean Shaft Area: Clean any debris, dirt, or old line fragments from the trimmer shaft and the area where the housing attaches.
4. Align New Spool Housing: Carefully align the molded shape of the new 90529876 spool housing with the corresponding shape on the trimmer shaft. This alignment is crucial for the housing to seat properly and for the screw hole to match. You may need to rotate the housing slightly until it slides down onto the shaft.
5. Secure Housing: Once the housing is correctly aligned and seated, reinsert the screw removed in step 2. Tighten the screw firmly but do not overtighten, as this could strip the threads or damage the housing.
6. Install Line Spool (Sold Separately): If you are also replacing the line spool, install it into the new housing according to your trimmer's specific instructions. Ensure the line is properly threaded through the metal eyelets.
7. Test Functionality: Reconnect the trimmer to its power source and briefly test its operation in a safe, open area to ensure the housing is secure and the line feeds correctly.

5. Operating Considerations

The 90529876 Spool Housing is designed to work with your trimmer's automatic line feed system. When the trimmer is in operation, the housing facilitates the release of additional trimmer line as needed. For optimal performance:

• Ensure the correct type and diameter of trimmer line are used with your specific BLACK+DECKER model.
• Avoid striking hard surfaces excessively, as this can prematurely wear the housing and the line.
• If your trimmer uses a 'tap and feed' mechanism, gently tap the housing on the ground while the trimmer is running to advance the line. If it has an automatic feed, the housing works in conjunction with internal mechanisms to feed line when the trigger is released and re-engaged.

6. Maintenance

Regular maintenance of your spool housing can extend its lifespan and ensure consistent performance.

• Cleaning: Periodically clean the spool housing to remove grass clippings, dirt, and debris. Use a brush or cloth; avoid harsh chemicals.
• Inspection: Regularly inspect the housing for cracks, excessive wear, or damage, especially around the metal line exit points. Replace the housing if significant wear or damage is observed.
• Line Management: Ensure the trimmer line is wound correctly within the spool (sold separately) to prevent tangles and ensure smooth feeding through the housing.
