   • While holding the safety button, pull the bail switch lever towards the handle.
   • Release the safety button once the motor starts.

3. Stopping the Mower: Release the bail switch lever. The blade will stop rotating within a few seconds.

7. Maintenance

Regular maintenance ensures optimal performance and extends the life of your lawn mower.

• Cleaning: After each use, disconnect the battery and clean the mower deck and exterior with a damp cloth. Remove any accumulated grass clippings from the underside of the deck and around the blade. Do not use water jets or harsh chemicals.
• Blade Inspection: Regularly inspect the cutting blade for sharpness and damage. A dull or damaged blade can lead to poor cutting performance and strain the motor. Replace or sharpen the blade as needed. Always wear heavy-duty gloves when handling the blade.
• Storage: Store the mower in a dry, well-ventilated area. Ensure the handle is folded for compact storage if desired. Remove batteries before long-term storage.
