I have the mini mac pump and last night it started to stick. As I use it it grates a little. I seem to remember some info about it needing regreasing but couldn't find it on the site. Anyone have any tips thanks rob

Sounds like you need to undo the two top screws and the minimalist amount of Vaseline around the inside of the tube. If you put too much it will not work and slip.

Brill thanks graham!

Also, I once found a balloon had gotten sucked down into mine.  It was quick to unscrew and take the top off.  I also reapplied the Vaseline.  Works like new!
