thanks Rod...it is two different places but both affected by how often and how long the machine is used. The service tech that did the overhaul on our Amaya last month went over with us what to oil, when to do it, and then talked about our 'normal' routine use of the machine. He said that just letting it sit without use...which can be sometimes a week or more...is just as bad as using it for 24 hours straight! We hadn't thought that oil would evaporate-it does. He explained how some of his customers have a regular schedule of cleaning and oiling besides that called for by the program. Those that use them all day every day, start the morning off with a cleaning, checking needles, oiling and checking bobbin, and a couple extra drops of oil where we do when in use. Others, like us that let it sit for long periods, he recommended starting off the same way-if it has set for a week of unuse, clean and oil everything-even if just an extra drop or two on the needle bar and reciprocator-and then follow recommended guidelines as it is used. Typical for us, like today-is a quick one or two 'retail' jobs-then it sits until I get a commercial order-last week for two days we did sweatshirts for a swim team-15-20 sweats, front and back-two days. Then a quick 2 crewneck sweats for a 'retail' order..then it sat all week until this morning for an 'emergency' fleece vest award for a group. Not a single other job scheduled for it...yet! So if it sits, I would get the oil bottle out by the end of the week and 'touch up' where needed. Just did the 4 mil. oil job at the end of the sweatshirt run-so I leave that alone for awhile, otherwise I would 'top it off'. The service tech was great about walking through our normal routine and set up a 'tailored' maintainence routine for us to prevent any further problems like he found. So if you can get a service tech out-do the same-sit down and go over when and how you use the machine and what he would recommend for 'preventative' maintainence based on your use! Well worth it! He came out FREE because we renewed the warranty contract-and will be over once a year, everytime we renew. Roland
