It features a 44cm cutting width and offers multiple cutting height adjustments to suit various lawn conditions. The mower is equipped with a grass bag for collecting clippings, and a grass bag full indicator to alert the user when it needs emptying.

Maintenance Features:
- Regular Cleaning: The underbody and cutting blade should be kept clean and free of debris. Clippings should be removed from the discharge chute.
- Blade Maintenance: Nuts and bolts should be checked regularly. The cutting blade should be lubricated after each use to prolong its lifespan. Worn or damaged blades should be replaced with genuine manufacturer parts. The manual provides instructions for replacing the cutting blade, including tightening specifications (16 Nm min, 20 Nm max). It is recommended to replace the cutting device after 50 hours of mowing or 2 years, whichever comes first.
- Battery Care: Batteries should be protected from moisture and water and stored within a temperature range of 5°C to 45°C, away from direct sunlight. They should be cleaned regularly with a soft, dry brush. To prolong battery life, it is recommended to charge the battery every six months during extended periods of non-use.
- Storage: When not in use, the mower should be stored out of reach of children. For reduced storage space, the upper handle can be folded down by unscrewing the wing nuts. The product should be protected from dust, ideally using its original packaging or a suitable cover.
