'4 There are two openings in the rim of the stitch width dial, one on the left and the other at the back (see arrows). These openings are the oil holes of the zigzag mechanism. Do not lubricate the bobbin winder. The raceway in the sewing hook is the most important oiling point. Put one drop of oil into the raceway each day you sew. From time to time, remove the needle plate and clean the machine feed with a soft brush Take a toothpick and remove accumulations of packed lint. Take out the bobbin case and the bobbin and clean the vicinity of the sewing hook. Before you begin to oil the mechanism under the arm top cover and at the needle-bar end of the machine, remove the dirt and lint which have accumulated on these parts. DR 6fl DR 610 23 / L
