Oiling a RW

As im still new to rotaries and I have a FLY and a 6v RW and a new slimline 12v RW on the way. I was just wondering what parts of the RW to oil ? do I just drop some two in one oil in the top bit and thats it ? or do I need to oil other parts as well ?

Many thanks for any elp.

Pretty much just the slide. That's the piston that moves up and down.

3In1 oil mate, drop it on the top of the machine mate and run for a bit , and a tiny drop on the bearings buddy and ya good to go

Thanks folks :) .
