This Water-Fed polisher allows you to sand down your pots. It comes with a 4″ aluminium velcro backer pad – so you can stick your sanding pads to it easily.

Compressed air should be dry and cool, as high-moisture air will lead to internal rusting that could cause machine failure.
the air pressure should normally be maintained at 90PSI~116PSI(0.62MPa~0.8MPa).
Always supply adequate water during operation.
To avoid machinery failure during operation, make sure the machine is filled with 10# oil before operation.
When putting your grinder away, especially if it will be not used for a period of time, the machine should be well oiled and turned on for almost five seconds without bearing a load before turning it off. This is important to avoid rusting.
