Bobbin Case Maintenance
In a normal production setting, the bobbin case should be cleaned/checked
every 4 to 6
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 bobbin case will need to be replaced.
Cleaning the Bobbin Case
1. When the bobbin case is removed for cleaning, check the lever for wear.
2. Brush lint and dust out of the bobbin case with a small, soft-bristle brush.
3. Replace the bobbin in the bobbin case and test the tension.
Hook Assembly Maintenance
The hook assembly should be
cleaned every 4 to 6 hours
when the machine is used in a
normal production setting. 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 excess oil can drip off
the assembly.
Oiling the Hook Assembly
1. With all lint and dust removed from the hook assembly, place one small drop of clear
sewing machine oil in the raceway. A hypodermic oiler 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.
