Is it not working or just making a lot of noise? They all grind and squeal somewhat not like they are silent.
Do you have another to compare it to? There are a lot of different theories for lubes here: Graphite, wd 40, oil, sewing machine oil, lard, spit etc.....They make noise but if they are not working correctly some "light lubrication" would be proper. Less is better in this case. Oil draws dirt and dust, wd 40 dries out, s/m oil same as above, lard cooks great in a cast iron skillet! And Buzz is the one with lubricating saliva. Everybody has their own opinion, so like the last crusade "choose wisely". But err on the side of caution, don't get too much junk on anything else.
