4. Operating Instructions
The WORX WG509 offers three primary functions: blowing, vacuuming, and mulching. Switching between modes is quick and intuitive.
4.1 Switching Modes
To switch between blower and vacuum/mulcher modes, locate the large knob or lever on the side of the unit. Rotate or slide it to the desired setting. Ensure the mechanism clicks into place before operation.

4.2 Blower Operation
In blower mode, the tool delivers up to 350 CFM (Cubic Feet Per Minute) of air volume and 210 MPH (Miles Per Hour) air speed. Use this mode to clear leaves and debris from hard surfaces or to gather them into piles.
- Direct the nozzle towards the debris you wish to move.
- Utilize the variable speed control to adjust airflow for different tasks, from light sweeping to heavy debris removal.

4.3 Vacuum and Mulcher Operation
In vacuum mode, the tool collects leaves and debris, which are then mulched by the metal impeller at an efficient 18:1 ratio before being deposited into the collection bag. This significantly reduces the volume of yard waste.
- Ensure the collection bag is securely attached.
- Guide the vacuum nozzle over the leaves and debris.
- The tool can reach into narrow spaces, such as under patio furniture, for thorough cleaning.
- The design allows for comfortable one-handed operation.
