Daily Maintenance
With the machine running, spray the hook area generously with WD
40 to flush out lint particles that may be inside the hook race. The
“race” is the area between the bobbin basket (the dark part of the
hook assembly where the bobbin case nestles in) and the hook (the
silver part that moves around the bobbin basket in a counter-
clockwise motion)—see Photo A on previous page. Allow the
machine to run 10-15 seconds to throw off the excess WD 40.
SAFETY NOTE: Do not use a rag to remove lint from the
area while the machine is running!
Keep your hands away from the rotating hook assembly
while the machine is running!
Stop the machine by tapping the toggle button on any handle again.
