Think of it like this...varibles....if we were sewing on broadcloth all day, waiting for the 200,000 stitch timer to come up wouldn't be so bad. But, then consider sewing on fleece or caps with buckram linings and the dust and lint that is generated from sewing on these garments...it gets into the bobbin case area and soaks up the oil, drying it up...well you get the idea. A story...I put a brand new hook on a customers machine, oiled it and instructed them to oil it every morning or every four hours, just as Sharon has mentioned in her post. Six weeks later, the customer called and said their machine would not work..would not move, could't turn the Z-axis over by hand, etc. The customer lived 7 hours from us....so away we go on a tech call. We find that since we had left, this customer had let the machine sit idle, it was in the middle of the summer and the machine had not not been used. The oil had evaporated. Strike one. The rotary hook was frozen solid. They did not oil the hook on startup...when asked why...well the "timer" had not popped up yet. Strike two. They were sewing on fleece that was creating lint and dust. Strike three,and if there were a Strike four, it would have been the fact that it was a brand new, nice tight rotary hook. When looking at the total number of stitches that this rotary hook had on it since we left and it's last oiling, we saw that it was in the 170,000 stitch range. This is only one story. This same issue with dust and lint, dry heat and all the other varibles that come into play applies to the needle bars, reciprocator shaft,takeup lever cam disk or any other areas that are open to collect lint and dust and is open to the air. Auto lubrication was mentioned in a post above, the difference with that comparrision is that in an automobile, for the most part, we are dealing with sealed bearings and a crankcase that is sealed off from direct contact with the external environment. If they weren"t, they wouldn't last very long.....anyway...thought I would give just a couple of reasons why we do and say what we do.....they say experience is the best teacher, but in the embroidery world there are some things better off not having experienced....they are just too costly! But on the other hand, it may be good for us techs....gee....maybe giving out all this advice isn't such a good idea....hummmmm....
