How do I correctly operate my Portable Vacuum Cleaner?

Start your engine and plug the vacuum's plug into your 12V DC socket. Push switch to turn the vacuum on or of. Direct the nozzle of the vacuum onto the area you wish to clean. To empty the dust tank, press the dust tank release button to detach the tank from the vacuum. Then simply pull out the HEPA filter and empty the dust tank. Place the filter back into the dust tank and press firmly to ensure a secure fit. Place the dust tank back onto the vacuum until it "clicks" firmly into position. Turn off and unplug when not in use.
