I work in a shop that has a Nardini 1440 (green color). The lathe is new to us and we are having trouble figuring out the controls. The manual is, of course, useless. Of greatest concern is that we can't get the carriage or the cross slide to travel automatically in both directions. They only go in one. The lever governing this doesn't seem to be working. Could the problem be low oil? It is very low on oil (we have some on order). If not, some suggestions would be greatly appreciated. It also has a lot of backlash. Is there a video or a publication that details how to tighten the gibs? I'd love to correspond with anyone who can help out a newbie, as the boss is not a machinist. Thanks.
