  If your Black & Decker Lawn Mower's motor stops while mowing, first, ensure the bail handle and switch lever are in the “off” position, and remove the Safety Key. Then, turn the mower over and check that the blade is free to turn. You might also try raising the cutting height of the wheels to the highest position and restarting the mower. Check if the battery has been fully charged by plugging in the charger and waiting for the green light. Also, the circuit breaker may have tripped, it resets automatically, but the re-set time could be as long as 1 minute. Try to slow down or raise the cut height.

  If your Black & Decker Lawn Mower runs but the cutting performance is unsatisfactory, ensure the battery has been fully charged. Also, make sure the bail handle and switch lever are in the “off” position, remove the Safety Key, and check the blade for sharpness, and the deck and discharge chute for clogging. If the wheel height adjustment may be set too low for grass condition, raise the cutting height.

  If your Black & Decker Lawn Mower is abnormally noisy and vibrates, ensure the bail handle and switch lever are in the “off” position, and remove the Safety Key. Turn the mower on its side and check the blade to ensure it hasn't been bent or damaged. If the blade is damaged, replace it with a Black & Decker replacement blade. If there is no visible damage to the blade and the mower still vibrates, return the mower to an authorized Black & Decker service depot.
