9. Lubrication (Machine Maintenance)
NOTE! It is important to clean the machine before oiling. Keep all areas of the machine clean of
built–up lint and dust. (Lubrication is required on the hook assembly and sewing head.)
Different parts of the machine requires different types of lubricants and different lubrication
frequencies and it is very important to follow these instructions in order to keep the machine
running properly.
Bobbin Case Maintenance
In a normal production setting, the bobbin case should be cleaned every four hours. Brush
lint and dust out of the bobbin case. Failure to keep the bobbin case clean can cause tension
problems. If tension is adjusted without first removing dust and lint, the tension spring on
the bobbin case can be bent too far and the case will need to be replaced.
Cleaning the Bobbin case
1. When the case is removed for cleaning, check the shaft for wear.
2. Brush lint and dust out of the case with a small soft-bristle brush.
3. Replace the bobbin in the case and check and adjust tension.
Hook Assembly Maintenance
The hook assembly should be cleaned every four hours of normal machine operation. The
hook assembly should be oiled every 4 to 6 hours.
Cleaning the Hook Assembly
1. Remove the bobbin case from the hook assembly.
2. Brush any lint or dust from the hook assembly with a small stiff-bristle brush. If you
can’t remove all the lint/dust with a brush, use compressed air to blow the hook
assembly clean.
*It is best to oil at the end of the day, when the machine will be idle so any excess oil can
drip off the assembly.
Oiling the Hook Assembly
1. With all lint and dust removed from the hook assembly, place one drop of clear sewing
machine oil in the raceway. A hypodermic oilier works best because it offers greater
control over how much oil is dispensed.
2. Sew off the machine on practice cloth to prevent oil stains on production goods.
