5.2 Switching Modes (Blower/Vacuum/Mulcher)
The RB 40V 3-in-1 unit features a quick-shift mechanism for seamless transition between modes:
- Blower Mode: Ensure the mode switch is set to "Blowing". This mode is ideal for clearing leaves and debris from lawns, driveways, and patios. The maximum air speed is 52m/s (116 mph) with a maximum volume of 264m³/h.
- Vacuum/Mulcher Mode: Rotate the mode switch to "Vacuum". In this mode, the unit vacuums leaves and debris into the collection bag while simultaneously mulching them. The mulching ratio is 30:1, significantly reducing the volume of collected material. Maximum suction is 45.9m/s (350 CFM).
