Maintenance

Regular maintenance ensures the longevity and optimal performance of your BLACK+DECKER tools. Always disconnect the tool from the power source before performing any maintenance.

General Maintenance

• Cleaning: After each use, clean the exterior of the tools with a damp cloth. Do not use strong detergents or solvents. Keep ventilation openings free of debris.
• Cord Inspection: Regularly inspect the power cord and extension cord for any signs of damage, cuts, or fraying. Replace damaged cords immediately.
• Storage: Store tools in a dry, secure place out of reach of children. Protect blades and cutting lines from damage during storage.

BEHT150 Hedge Trimmer Blade Care

• Blade Cleaning: Remove sap and debris from the blades after each use. A stiff brush can be used.
• Blade Lubrication: Periodically lubricate the blades with a light machine oil or blade lubricant to reduce friction and prevent rust. Apply a thin film along the cutting edge.
• Blade Sharpening: If the blades become dull, they can be sharpened by a qualified service technician. Do not attempt to sharpen them yourself unless you have proper training and tools.

  3. Remove the empty spool.
  4. Insert the new pre-wound spool, ensuring the line is threaded through the eyelet.
