Installation; Power Table - Brother LK3-B438E MKII Instruction Manual

3. INSTALLATION

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.

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.
