Decided to grease the kingpins this morning. When away from my compressor I have a very nice grase pistol that takes cartridges. The socket at the end of the flexible tube pops on the nipples quite easily and grips well. It never pops off by itself and never leaks.
That is the problem. It goes on the nipple easily enough but doesn't want to come off. The bottom one can be prised off with a screw driver blade but when on the top nipple there is not a point to lever against and it requires a lot of tugging to get it off.
I now have two nicely skinned knuckles
Note to self: Next time wear the gloves you knew that you should have been wearing in the first place
