Replacement of parts should only be carried out by a 
qualified technician. 

Use only the proper replacement parts as specified 
by Brother. 

Turn off the power switch and disconnect the power 
cord before replacing any parts. 
The machine may operate if the treadle is depressed 
by mistake, which could result in injury. 

 
 

 

 

Use both hands to hold the machine head when 
tilting it back or returning it to its original position. If 
only one hand is used, the weight of the machine 
head may cause your hand to slip, and your hand 
may get caught. 
Be sure to wear protective goggles and gloves when 
handling the lubricating oil and grease, so that they 
do not get into your eyes or onto your skin, otherwise 
inflammation can result. 
Furthermore, do not drink the oil or eat the grease 
under any circumstances, as they can cause 
vomiting and diarrhea. 
Keep the oil out of the reach of children.
