5. Operating Instructions
5.1. Charging the Battery
Before first use, fully charge the battery using the provided system charger. The charger has LED indicators to show the charging status. A full charge typically takes approximately 1 hour for the 3.0 Ah battery.
5.2. Adjusting Cutting Height
The lawnmower features a 3-stage axial cutting height adjustment, ranging from 30 mm to 70 mm. To adjust, locate the adjustment levers near the wheels. Pull the lever outwards and move it to the desired height setting. Ensure all four wheels are set to the same height for an even cut.

5.3. Starting the Lawnmower
To start the lawnmower, press and hold the safety button on the handle, then pull the switch lever towards the handle. The motor will start. Release the safety button once the motor is running. To stop, release the switch lever.
5.4. Mowing Technique
For best results, mow in straight, overlapping lines. Avoid mowing wet grass, as it can clog the mower and lead to an uneven cut. For very tall grass, it is recommended to make two passes, setting the cutting height higher for the first pass and then lowering it for the second.

6. Maintenance
6.1. Cleaning
After each use, remove the battery and clean the mower. Use a brush or cloth to remove grass clippings from the cutting deck, wheels, and grass collection basket. Do not use water to clean the motor housing or electrical components.
6.2. Blade Care
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.
6.3. Battery Storage
Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures. For long-term storage, ensure the battery is partially charged (around 50%) to prolong its lifespan.
6.4. Storage of Lawnmower
The folding shaft allows for space-saving storage. Clean the mower thoroughly before storing it in a dry, protected area. Ensure the grass collection basket is empty.
