There's a man working a bicycle wheel with various tools.  He starts off by turning the axle of the wheel with a pair of tongs to position the axle in the center.  Then he fixes the center nut and uses a wrench to loosen it.  Then he uses his hands to remove the axle out.  He uses another tool to unscrew a washer out of the axle.  Then he uses a tool with a magnetic end to remove tiny metal particles out of the axle.  After that he cleans the inside rim of the greasy axle with his finger.  Then he takes the washer and cleans it further to fix it back into the axle.
