Lubricating the machine 
  
How often you need to lubricate the machine depends 
on how often you use it and where you keep it. The 
following general guidelines assume that you will be 
sewing several times a week. But it you use your 
machine more frequently, lubricate it more often than 
the guidelines suggest.
 
  
Approximately once a year, lubricate all moving 
connections as shown, to ensure freedom of 
movement and to protect metal parts from excessive 
wear.
 
  
To determine which connectors move and need 
lubrication, turn the handwheel slowly, by hand, while 
face plate is removed.
 
  
When lubricating, apply only SINGER* oil at the points 
shown. SlNGER*oil is specially prepared and does not 
contain harmful deposits that can interfere with the 
smooth action of precision parts.
