ADJUSTMENTS
CAUTION
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.
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.
Secure the table so that it will not move when tilting
back the machine head. If the table moves, it may
crush your feet or cause other injuries.
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.
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 treadle 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 and knife
Always be sure to turn off the power switch and then
wait one minute before opening the motor cover. If
you touch the surface of the motor or the motor
bracket, it may cause burns.
If the power switch needs to be left on when carrying
out some adjustment, be extremely careful to
observe all safety precautions.
13-1. Adjusting the safety switch position
The standard position for the safety switch (1) is when the
distance (b) between part (a) of the safety switch plate (2)
and the table is set to 13.5 mm as shown in Figure [A].
If the processing method for the table results in distance (b)
being too wide, it may adversely affect the operation of the
safety switch (1).
<Adjustment method>
If distance (b) is greater than 13.5 mm, use the two screws
(3) to adjust the vertical position of the safety switch plate (2)
as shown in Figure [B].
