4. Setup and Assembly

- Unfolding the Handles: Carefully unfold the main handle assembly from its folded storage position. Secure the handle sections using the quick-release levers or knobs provided. Ensure the handles are firmly locked in place.

- Attaching the Grass Collection Box: Assemble the grass collection box if it came in multiple pieces. Lift the rear flap of the mower and hook the grass collection box onto the designated slots at the back of the mower. Ensure it is securely seated.
- Inserting Batteries: This model requires two 18V Power X-Change batteries (not included). Open the battery compartment cover, typically located on top of the mower deck.

5. Operating Instructions
Before starting, ensure the grass collection box is properly attached and the batteries are fully charged and inserted.
- Adjusting Cutting Height: The mower offers 6 levels of cutting height adjustment. Locate the central cutting height adjustment lever, usually on the side of the mower deck. Move the lever to select your desired cutting height. Ensure it locks into position.
- Starting the Mower: To start the mower, first press and hold the safety button located on the handle. While holding the safety button, pull the bail lever (operator presence control) towards the handle. The motor will start. Release the safety button once the motor is running, but continue to hold the bail lever to keep the mower operating.
- Mowing Technique: Push the mower forward in overlapping rows. For best results, mow in straight lines. Avoid overloading the motor by attempting to cut excessively long or wet grass too quickly.
- Grass Collection: The 45-liter grass collection box features a fill indicator. When the indicator shows full, or when you notice a decrease in cutting performance, empty the grass box.
- Stopping the Mower: To stop the mower, simply release the bail lever. The motor will immediately shut off.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your lawn mower. Always disconnect the battery pack before performing any maintenance.
- Cleaning: After each use, clean the underside of the mower deck to remove grass clippings and debris. Use a brush or a damp cloth. Do not use a high-pressure washer directly on the motor or electrical components.
- 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. If necessary, have the blade sharpened or replaced by a qualified service technician.
- Grass Box Cleaning: Empty and clean the grass collection box regularly to prevent blockages and maintain airflow.
- Battery Care: Store batteries in a cool, dry place. Do not expose them to extreme temperatures. Charge batteries fully before long-term storage.
- Storage: Store the mower in a dry, protected area. The folding handles allow for compact storage.
