3. Operation
The RIDGID WD1450 offers powerful suction for both wet and dry applications, as well as a blowing function.
3.1 Dry Vacuuming
Ensure the 3-layer fine dust filter is properly installed for dry debris collection. Connect the hose to the front inlet port. Use the utility nozzle for general cleaning, or the car nozzle for upholstery and tight spaces. The 6 peak HP motor provides strong suction for tough job site clean-up, including sawdust and other dry debris.

3.2 Wet Vacuuming
When vacuuming liquids, remove the dry filter. The vacuum is designed to pick up small amounts of liquid with the wet nozzle. The 14-gallon capacity allows for significant liquid collection. After wet use, empty the drum using the built-in drain plug.
3.3 Blowing Function
To use the blowing feature, connect the hose to the exhaust port located on the back of the motor head. The powerful exhaust airstream can be directed through the vac hose to blow debris from garages, decks, and sidewalks.
