You can buy a pointed nipple at an auto parts store that fits over a grease gun nozzle for the pedal crank and variator mini zerk fittings. First use a small pointy nail to clean the orifice and see that the spring loaded tiny ball will go in and out. Then just 1 pump into the variator so it doesnt get into the starter shoes, after the gun is primed. I use an old toothbrush and coat the inside of the chains lightly with grease and then wipe with a rag to take off the excess. That minimizes the grease on the rims.
