2. Grass Box Assembly:

   Assemble the two halves of the grass collection box if they are separate. Then, securely attach the assembled grass box to the rear of the mower. Ensure it clicks into place correctly to prevent grass clippings from escaping.

3. Cutting Height Adjustment:

   Before starting, adjust the cutting height to suit your lawn conditions. The BEMW451-QS offers 3 cutting heights: 23 mm, 43 mm, and 63 mm.

Operating Instructions

Follow these guidelines for effective and safe operation of your electric lawn mower.

1. Connecting to Power:

   Plug the mower's power cord into a suitable outdoor-rated extension cord, ensuring the extension cord is rated for the mower's power requirements (1200W). Connect the extension cord to a grounded outdoor power outlet.

2. Starting the Mower:

   To start the mower, press and hold the safety button, then squeeze the bail lever towards the handle. Release the safety button once the motor starts. The E-DRIVE technology ensures high and consistent torque, even in taller or wet grass.

3. Mowing Technique:

   Mow in overlapping rows, slightly overlapping the previous pass to ensure even coverage. For best results, mow when the grass is dry. The EDGEMAX system allows for efficient mowing close to borders and obstacles.

4. Stopping the Mower:

Maintenance

Regular maintenance ensures the longevity and optimal performance of your BLACK+DECKER lawn mower. Always disconnect the power supply before performing any maintenance.

• Cleaning: After each use, clean the mower deck and grass box. Remove any accumulated grass clippings from the underside of the deck using a brush or scraper. Do not use water jets or high-pressure cleaners directly on the motor or electrical components.
• Blade Care: The new design blade with fins ensures optimal grinding and chopping, reducing jamming. Periodically inspect the blade for sharpness and damage. A dull or damaged blade can affect cutting performance and put strain on the motor. If necessary, have the blade sharpened or replaced by a qualified service center.
• Grass Box Emptying: Empty the grass box regularly, especially when it is full, to maintain efficient grass collection and prevent clogging.
• Storage: Store the mower in a dry, well-ventilated area, away from direct sunlight and moisture. The handle can be folded for compact storage.
