4.3 BCSS820 Hedge Trimmer Operation

• Starting: Insert a charged 20V battery. Press the safety switch (often a two-hand operation for safety) and then squeeze the trigger to start the hedge trimmer.
• Trimming: Use the appropriate blade (4-inch or 8-inch) for the task. The 3/8-inch cut capacity is suitable for detailed trimming around shrubs and cutting small branches or weeds. Maintain a steady, even motion.
• Interchangeable Blades: Blades can be swapped without tools for maximum versatility. Refer to the hedge trimmer's specific instructions for changing blades.

5. Maintenance

• Cleaning: After each use, ensure the battery is removed. Clean all tools with a damp cloth. Remove any grass, leaves, or debris from vents and cutting mechanisms.
• Blade Care (Hedge Trimmer): Regularly inspect blades for sharpness and damage. Sharpen or replace dull blades as needed. Apply a light coat of machine oil to the blades after cleaning to prevent rust.
• Trimmer Line Replacement (String Trimmer): When the trimmer line runs out, replace the spool with a new BLACK+DECKER compatible spool. The Auto Feed System is designed for specific line types and spools.
• Battery Storage: Store batteries in a cool, dry place away from direct sunlight and extreme temperatures. Do not store batteries in a discharged state for extended periods.

6. Troubleshooting

• Tool Not Starting: Ensure the battery is fully charged and correctly inserted. Check that all safety switches are engaged before pressing the trigger.
• String Trimmer Line Not Advancing: Verify the spool is correctly installed and the line is not tangled or jammed. The Auto Feed System should advance the line automatically. If not, the spool may need replacement.
• Reduced Power/Run Time: This typically indicates a low battery charge. Recharge the battery fully. If the issue persists with a fully charged battery, the battery or tool may require service.
• Hedge Trimmer Blades Jamming: Ensure the battery is removed. Clear any lodged branches or debris from between the blades. Avoid cutting branches thicker than the specified 3/8-inch capacity.
