Regular cleaning, oiling and care of the machine ensure satisfactory sewing and a long life for the machine. When not in use, keep machine covered to prevent dust from settling on it.
Always remove lint deposit, dust and thread bits before oiling any part of the machine. Use a small dry brush or old tooth brush and a soft cloth to remove dust and lint. Use a pointed instrument like a needle to pick out bits of thread and lint that cannot be brushed out. To clean the feed dog, remove the needle plate of the machine and brush off all lint deposits and dirt sticking to the feed mechanism. To clean the shuttle race remove the two screws holding the shuttle race assembly to the machine, take out the shuttle race and wipe its groove free of dirt, fluff and broken bits of thread. Some times loose thread wind around the pivot of the treadle and make the machine hard to run. Remove thread bits which are caught in the wheel and all lint and dust sticking to the treadle parts.
It is necessary to oil and lubricate the machine periodically. If the machine is used every day, oil it once a week. If you use it infrequently, then oiling once a month is sufficient. To oil thoroughly remove the upper thread, needle plate, slide plate, face plate, bobbin case, needle and presser foot. Read the instructions manual for location of parts that need application of oil.
Applying machine oil to all oiling holes and joints where one parts rub against another. One drop of oil is enough for each point. While oiling turn the flywheel back and forth to help the oil flow to the moving parts. It is essential to oil the shuttle race. After oiling the points on the head of the machine, tilt the machine head back to oil the parts on the under side. On a treadle machine, the belt will have to be released before tilting the machine head back. Do not forget to oil the pivots of the treadle. When the machine has been thoroughly oiled, wipe away excess oil and run it slowly for several minutes on a waste piece of material. Place a scrap of fabric under the presser foot and lower the needle before closing. The fabric will absorb the excess oil that will drain down through the machine and will prevent formation of oil spots on the fabric.
If the machine becomes gummed with oil, put a drop of kerosene in each oil hole and at joints and run it rapidly for several minutes. Then wipe off the oil that oozes out with a soft cloth and reoil the machine. It will need a second oiling within a few hours after this treatment. The motor of electric sewing machine needs periodic greasing done by a qualified service agent.
