A Happy Machine is a Clean Machine
Every December there is a phenomenon of hope that almost all of us enjoy. It is the New Year’s Resolution. Whether large or small, achievable or not, most resolutions shrivel from existence by April Fools’ Day. Don’t despair, here is one that is easy to commit to and easy to keep. Keep your sewing machine clean!
Here’s how to do it.
Clean the lint out of the bobbin chamber after every sewing session. If the machine has a vertical (front or end loading) bobbin case, sweep with a small brush or vacuum it. If it is a horizontal, top loading, bobbin case, vacuum it thoroughly. This style of bobbin is prone to collect debris between the rotating hook and the feed dog yoke. Under no circumstances should a bobbin chamber be blown out.
We recently had a service customer who told us that at a prior service, the technician “just blew air into the bobbin and charged me”. Upon removing the covers, we found all that dirt, sitting on the bearings, control mechanisms and circuit board.
Change the needle frequently; about every eight hours of stitching. Figure one hour of actual sewing time for every eight to ten hours in front of the machine. Needles will get dull, or bent into a “micro-hook” after time. Also, the eye will get worn. Considering that the same length of thread passes through the eye about eighty times during sewing, that’s a lot of abrasion on the eye. Thread breakage or a popping sound indicates it’s time to change that needle.
A drop of oil on the hook race at time of needle change will make the machine run quieter and happier. This pertains to front loading bobbins where the metal hook runs in a metal race. With drop-in bobbins, the carrier is usually an inexpensive composite material and is designed to wear out over time.
Use fresh thread. If your thread comes on a wooden spool, use it for homemade toys, not for sewing. Wooden spools are antiques and so is the thread on them. And if you need to change bobbin thread, use an empty spool. Don’t wind new thread over existing thread. Of you have to, strip out the spool. The minor time and expense of doing that far exceeds the grief and misery of a major jam.
Mind your tensions. Thread looping underneath is almost always caused by improper upper tensions. Before you bundle up the machine and bring it in, call us and we will walk you through an adjustment procedure. But be prepared, the first thing we will ask is, “Did you raise the presser foot before you threaded the machine?” TNT
