Why does my Black+Decker CLM5448PC Lawn Mower motor stop while mowing?
- A
  Amanda DennisAug 3, 2025
  If the Black+Decker Lawn Mower's motor stops while mowing, several factors could be at play. First, turn the mower off by releasing the bail handle, remove the safety key and battery pack, and ensure the blade can turn freely. Next, try raising the cutting height. Also, check the battery cavity for debris and proper connection. Verify the battery is fully charged by pressing the state of charge button. To prevent overloading, reduce your cutting pace or increase the cut height.

What to do if Black+Decker Lawn Mower is not picking up clippings with bag?
- A
  Adam HerreraAug 13, 2025
  If your Black+Decker Lawn Mower isn't picking up clippings with the bag, the chute might be clogged. Turn the mower off, unplug it, and clear any grass clippings from the chute. Also, raising the cutting height of the wheels to shorten the length of the cut can help. Finally, remember to empty the bag more often, as a full bag can hinder pickup.

  If your Black+Decker Lawn Mower runs but the cutting performance is unsatisfactory, turn the mower off, unplug it, and check the blade sharpness and for any clogging in the deck and discharge chute. Keeping the blade sharp is essential. Also, ensure the wheel height adjustment isn't set too low for the grass conditions; raising the cutting height may improve performance.

  If your Black+Decker Lawn Mower is abnormally noisy and vibrates, immediately turn it off and unplug it. Inspect the blade for any bending or damage; replace it with a BLACK+DECKER replacement blade if needed. If the underside of the deck is damaged, return the mower to a BLACK+DECKER Authorized service center. If there's no visible blade damage, disassemble the blade assembly as described in the “Removing and installing blade” section, remove any debris, clean each piece, and reassemble.
