Maintenance and inspection of the sewing machine 

should only be carried out by a qualified technician. 
Ask your Brother dealer or a qualified electrician to 

carry out any maintenance and inspection of the 

electrical system. 
Turn off the power switch and disconnect the power 

cord from the wall outlet at the following times, 

otherwise the machine may operate if the foot 

switch is depressed by mistake, which could result 

in injury. 

• When carrying out inspection, adjustment and 

maintenance 

• When replacing consumable parts such as the 

rotary hook 

Hold the machine head with both hands when tilting 

it back or returning it to its original position. 

Furthermore, after tilting back the machine head, do 

not push the face plate side or the pulley side from 

above, as this could cause the machine head to 

topple over, which may result in personal injury or 

damage to the machine. 
If the power switch needs to be left on when carrying 

out some adjustment, be extremely careful to 

observe all safety precautions. 
If any safety devices have been removed, be 

absolutely sure to re-install them to their original 

positions and check that they operate correctly 

before using the machine.
