    Works well, I like the ability to control the speed and number of pumps if you choose to do so. I added a LockNlube pressure return valve on mine to make it easier to release off the fitting when they get too much pressure.

    Die Fettpresse ist super, gerade die Einstellung der zweiten Stufe ist super, wenn man große Wellen hat, in denen mal eine halbe Kartusche verschwindet. Ruck Zuck ist eine Kartusche leer. Für Lager nehme ich dann die erste Stufe. Super ist auch die Einstellung der Stöße die gemacht werden sollen. Nach den eingestellten Stößen hört sie automatisch auf.
