Before use:
Check the hoses, connectors, and media reservoir. If you need to add blasting media, or change to another type, clear the hopper before starting the machine.
Pull and release the cleaning mallets two or three times.
Check the desiccant before each use. Water or oil in the lines will lead to powder 'clumping up'.
After use:
Check all hoses and connections. Make sure pressure gauge drops to 0. Clean the glass lid with a soft cloth.
