Reference - Cleaning And Oiling

One of the most important parts of maintaining your machine is proper cleaning and oiling. Below are tips to fol-
low, but more complete instructions for your specific model can be found in your machine's manual.
It is recommended that you clean and oil every other bobbin, or every 3-4 hours of actual sewing time. If you
notice your machine sounding louder than usual, then it is time to clean and oil.
G en er al C lea ning Steps
• Turn the machine off and disconnect it from the power supply system.
• Clean the display using a soft slightly damp microfiber cloth.
• Remove the needle. (It is recommended that you change your needle every 4-6
hours of sewing time.)
• Remove the stitch plate.
• Clean the hook race with a brush and remove all lint and threads, using the brush
included with your machine..
O i l i n g th e N eedle Bar
If the needle bar lacks lubrication, the needle bar might not move smoothly.
If the machine is used often, the needle bar should be oiled every 6 months.
• Turn the machine off and disconnect it from the power supply.
• Remove the plug (1) and remove the screw (2).
• Remove the face cover (3). After removing the face cover, be careful of the
moving parts.
• Put one drop of oil on the needle bar movement mechanism, including nee-
dle bar crank rod/needle bar bracket and needle bar supporter (add the oil
on the area marked by arrow).
• Remove the presser foot.
• Turn the handwheel a few times and remove excess oil with a cloth.
• After oiling, the face cover must be remounted before plugging in the
machine. Never reconnect the machine or make it run with the place cover
removed.
