12. STANDARD 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.

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

If the power switch needs to be left on when carrying

out some adjustment, be extremely careful to

observe all safety precautions.

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.

Never touch the knife on the face plate when

opening the thread takeup guard cover, otherwise

injury may result.

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.

When removing the needle plate, auxiliary needle

plate and knife unit, use a screwdriver that matches

the size of the screw heads.

If a screwdriver with a size that does not match is

used, it may damage the screw heads and cause

personal injury or damage to the sewing articles.

touch the thread wiper.

1. Loosen the two screws (2).

2. Move the switch installation plate (3) to move the

actuator (1) to the desired position.
