Has anyone had experince taking one of these apart?
If so then maybe you can share some information on how to, as Water and crap has gotten into the Sander and instead of just throwing it away as It costed over £100, I thought I'd strip it and clean it all out just to see if she works.
No idea how that particular item comes to bits, but air tools are usually very simple and very reliable. Empty out what guck will run out. Use blow gun to get rid of as much as possible of the rest. Good squirt of WD 40 or similar and let soak. Connect to airline and see if there's any sign of movement. If there is, then fill up with light machine oil.
Beware -- if it starts running -- and the chances are high that it will -- then make sure it's inside a polythene bag with the end fastened tightly around the airline. The oil will go everywhere ............
