LK3-B430E-, B431E-, B432E-, B433E- Mark II

Machine installation should only be carried

out by a qualified technician.

Contact your Brother dealer or a qualified

electrician for any electrical work that may

need to be done.

The sewing machine head weighs more than

47 kg. The installation should be carried out

by two or more people.

Do not connect the power cord until installa-

tion is complete, otherwise the machine may

operate if the foot switch is depressed by mis-

take, which could result in injury.

Hold the machine head with both hands when

tilting it back or returning it to its original posi-

tion. Furthermore, after tilting back the ma-

chine 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.

All cords should be secured at least 25 mm

away from any moving parts. Furthermore,

do not excessively bend the cable or se-

cure it too firmly staples, otherwise there is

the danger that fire or electric shocks could

occur.

Be sure to connect the ground. If the ground

connection is not secure, you run the risk

of receiving a serious electric shock, and

problems with correct operation may also

occur.

Install the belt covers to the machine head

and motor.

CAUTION

3. INSTALLATION

3-1 . Power table

•

Use the power table which has been specially

designed for each sewing machines.

*

If using a commercially-available table, process

it as shown in the illustration below.

NOTE:

The thickness of the table should be at least 40 mm, and it should be strong enough to bear the weight and vibration of

the sewing machine.

If the distance A between the insides of the legs is less than 740 mm, move the control box installation position closer

to the motor (B = 247 mm).

Check that the control box is at least 10 mm away from the leg. If the control box and leg are touching, it could cause the

sewing machine to operate incorrectly.
