You push the right sized insert into the piston and tighten it up so it spreads to grip the inside of the piston and then using the slide hammer bit that's at the top of the box in the picture, wind it into the insert and then you pull/bang it out. So simple it, as David says, makes you smile and generally as a rule, say under your breath........"thats such a good thing".
Really good bit of kit Matt, highly recommended, even the cheap shite ones are good and do the job with minimum fuss. I think there's a vid on Youtube on how it works but its really simple....
