Operating Instructions
Dry Vacuuming
Ensure the cartridge filter is clean and properly installed. Plug the power cord into a grounded outlet. Flip the large ON/OFF switch to the "ON" position to begin vacuuming dry debris. The powerful 4 HP motor provides strong suction for various materials.
Wet Vacuuming
For wet pickup, the cartridge filter can be removed. The vacuum features a safety buoy technology that automatically shuts off suction when the liquid level reaches its maximum capacity, preventing overflow and motor damage. To empty liquids, use the built-in oversized drain port located at the bottom of the tank.

Blower Function
The rear blowing port allows the vacuum to function as a powerful blower. Simply attach the hose to the blower port to clear leaves, grass clippings, or other light debris from outdoor areas or workshops.

Maintenance
Emptying the Tank
For dry debris, unlatch the durable lid latches and carefully lift the motor head off the tank. Dispose of collected debris. For liquids, remove the drain cap from the oversized drain port at the bottom of the tank to allow liquids to flow out. Replace the cap securely after emptying.

Filter Care
The cartridge filter is washable and reusable. To clean, remove the filter and tap off loose debris. For thorough cleaning, rinse under running water. Allow the filter to air dry completely before reinstallation to maintain optimal performance and prevent mold growth.
