machine. . . , „
. Raise the needle bar to the highest position and remove the
needle and presser foot. , , *

. Clean lint and dust from the bottom of the needle plate and the
feed dogs with a lint brush.
• Turn the hand wheel slowly and be sure to clean all areas.
• Replace the removed plate.
Check the needle plate area, if there are scratches and rnarks
around the needle hole opening, your machine is not being clean^
ed properly. Always remove the needle plate and clean the feed
dogs periodically. Improper and lack of cleaning will cause an ac­
cumulation of lint which hampers the feeding mechanism this in
turn will cause the operator to impatiently pull or push the cloth
causing the needle to bend and strike the plate, foot or hook
causing a slip in the timing mechanism. Continuous striking will
cause defects making it necessary to call a serviceman.
