Troubleshooting
This section addresses common issues encountered while operating the Black and Decker GH900, offering practical solutions for restoring optimal performance and extending the tool’s lifespan.
Trimmer Runs Slowly
If your Black and Decker GH900 trimmer is running slower than usual, several factors could be the cause. First, ensure the trimmer is unplugged before performing any maintenance. A common issue is a restricted spool housing. Check if the spool housing can rotate freely; if not, carefully clean any debris or grass clippings that may be hindering its movement.
Also, verify that the cutting line does not extend more than approximately 5-3/8 inches (136mm) from the spool. Excessive line length can strain the motor and reduce cutting efficiency. If the line is too long, manually adjust it.
Furthermore, inspect the power cord for any damage that might restrict power flow. If the cord is damaged, it should be replaced by a qualified technician. If the problem persists after checking these components, consider consulting a professional for further assistance. Regular maintenance is also key to ensure the longevity of the trimmer.
Line Feeding Issues
Experiencing problems with line feeding on your Black and Decker GH900 is a common issue, often related to spool management. To resolve this, first ensure the trimmer is unplugged. Check the spool for proper winding; the line should be neatly and evenly wound, without overlapping or tangling. If the line is improperly wound, rewind it carefully, ensuring each layer is tight.
Inspect the spool housing for debris or obstructions that might prevent the line from feeding smoothly. Clean the housing thoroughly. Verify that you are using the correct type and diameter of line (0.065 in) specified for the GH900, as using incorrect line can cause feeding problems.
Also, check the automatic feed system (AFS) mechanism. Ensure it is free from dirt and moves without restriction. If the AFS is damaged, replacement parts may be required. Finally, consider replacing the spool if it is worn or damaged. Proper maintenance and using compatible parts are essential for reliable line feeding.
Maintenance and Care
Proper maintenance ensures the longevity and optimal performance of your Black and Decker GH900. Regular cleaning and correct storage are crucial for keeping your trimmer in excellent condition.
Cleaning the Trimmer
To ensure your Black and Decker GH900 trimmer operates efficiently and safely, regular cleaning is essential. Before you begin any cleaning, always unplug the trimmer from the power source to prevent accidental starts and potential injuries. Use a brush or dry cloth to remove grass clippings, dirt, and debris from the trimmer head, motor housing, and air vents.
Pay special attention to the spool housing, as accumulated debris can hinder the line feeding mechanism. Carefully clean the spool housing, ensuring it rotates freely. If necessary, use a mild detergent and a damp cloth to wipe away stubborn dirt. Avoid using excessive water, which could damage the electrical components.
After cleaning, inspect the cutting line and replace it if it’s worn or damaged. Allow all parts to dry completely before reassembling the trimmer. Regular cleaning not only improves performance but also extends the lifespan of your GH900.
Storing the Trimmer
Proper storage of your Black and Decker GH900 trimmer is crucial for maintaining its condition and extending its lifespan. Before storing, thoroughly clean the trimmer to remove any grass, dirt, or debris, following the cleaning instructions. Ensure the trimmer is completely dry to prevent rust or corrosion.
Store the trimmer in a dry, well-ventilated area, away from extreme temperatures and direct sunlight. Ideally, hang the trimmer on a wall using the provided storage hook or a similar device. This prevents the trimmer head from resting on the ground, which can damage the cutting line and the spool mechanism.
If hanging is not possible, store the trimmer horizontally on a shelf or workbench, ensuring it is stable and won’t fall. Protect the cutting line by wrapping it with a cloth or tape. Before long-term storage, consider removing the spool to prevent the line from becoming brittle or tangled. Finally, unplug the trimmer and store it in a safe place, away from children and pets.
