 the machine over on its back. Remove the thumb nut from the
 screw (E, Fig. 36) at the centre of the large cover plate under-
 neath the bed of the machine and remove the cover plate. Apply
oil to the oil holes and bearings indicated by the arrows in Fig. 36,
 and occasionally apply a small quantity of Singer Motor Lubri-
 cant to the teeth of the gears (D, Fig. 36), then replace the bed
 cover plate and fasten it as before with the thumb nut, being
 careful not to turn the thumb nut too tightly.
