Maintenance and inspection of the sewing
machine should only be carried out by a quali-
fied 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 carring out inspection, adjustment and
maintenance
· When replacing consumable parts such as the
rotary hook and knife
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.
