5. Operating Instructions
Once assembled and the battery is inserted, the YARD FORCE 24V Cordless Weeder Cultivator is ready for use. Always ensure you are in a stable position before starting.
- Weeding: Gently guide the cultivator over areas with weeds. The thin blades will entangle and remove weeds from their roots. For dense or tall weeds, make multiple passes or pre-cut them.
- Tilling: For tilling, apply slight downward pressure and move the cultivator across the soil. The powerful motor will break up compacted soil into a soft, fluffy texture suitable for planting. For deeper tilling, make repeated passes over the same area.
- Adjusting Depth: The depth of tilling can be controlled by the amount of downward pressure applied and the number of passes. The tool is designed for effective tilling of the upper soil layers in gardens and soft ground.
