Do you have any sandcarving equipment maintenance pointers?
The best advice I can give for maintaining your sandcarving machine is to treat it like your automobile. Do you change your oil in your car? Then you will want to purge, or clean, the system with high-pressure air, and possibly change out your abrasive every few years. Do you change your air filters in your car to have cleaner air and exhaust? Then you will want to change your dust collector filter to have a cleaner machine.
