Ok so pretty much when i got my Injecta it had some lube and the machine no instruction wich is sweet as >but i was wondering when to lube it <like everytime i use it ??after along long session?? once a month ? when it sticks??.its a pretty simple question but id rather ask then risk anything happening to the machine .It works so goodi love it and the results have really impressed me.Im working on some pieces at the moment wich are not finished but when they are i will post pictures.
