D B430E Outline
• What is the LK3-8430E?
LK3-8430E is asewing machine with electronic elements added to aconventionallockstitch bartacking machine. This machine offers higher efficiency, simpler operation and more
functions than the conventionallockstitch bar tacking machine does. Nevertheless, this machine has a reasonable price. This machine has good performance.
(See the left graph.)
Nine different types
of bar tacking patterns and three different types of straight bar tacking patterns have all been pre- Function
programmed.
Decorative bar-tacking patterns can also be sewn in a 3Qx1 0 mm sewing area.
· The conventional clutch mechanism and parts like the feed cam, worm, worm wheel, change gear, and power cam
have been eliminated.
· Variable sewing speeds can be changed easily from the operation panel.
• Sewing patterns can also be changed easily from the operation panel.
• Sewing pattern size can be enlarged or reduced from the operation panel.
• Foot switch pedal pressure has been reduced.
New mechanism
This machine adopts the R-8 feed mechanism.
Composition
of simple and compact parts has
allowed the realization of extremely high
speed and a more quiet feed mechanism. As
well, this mechanism offers fewer irregular
stitches and excellent durability.
*TheE of LK3-B430E has three themes, Electronic, Excellence, and Economy.

• Improved maximum high speed sewing, and easy variable speed setting
• Simple to change sewing pattern
• Simple pattern size enlargement/reduction by switch operation
• Easy maintenance due to elimination of clutch and parts like worm, worm wheel and change gear
• Lower noise due to no clutch noise
· 2-step foot switch making operation and productivity more efficient
(2-pedal foot switch is prepared as an optional part.)
• Almost same price as mechanical sewing machines even with the above-mentioned features equipped

Comparing B430E with BAS series electronic pattern sewers:
B430E is more suitable when
• Main use is bar tacking and pattern size is within 30x1 0 mm.
• High speed sewing is required.
· Low-cost sewing machine is required
BAS series electronic pattern sewers are more suitable when
• Not only bar tacking butalso pattern sewing is required.
• Pattern size exceeds 30x10 mm.
• Additional functions such as programming, intermittent work clamp lifter, and two-step
work clamp lifterare required.

3. Improved work efficiency
• The pressure of the foot pedal has been reduced. Starting sewing or lifting the work clamp can be performed
with a light touch, reducing operator fatigue.
4. Low cost and high performance
• With almostthe same price as a mechanical sewing machine, high speed sewing has been realized with a maxi-
mum of up to 2,500 spm, offering higher performance and efficiency. (Compared with 8430, productivity is in-
creased approximately
6%.)
5. Low noise, low power consumption
• As there is no clutch noise, this machine provides a quiet and comfortable work environment.
• Work clamp lifter sensor has been added to work clamp lifter mechanism to counter impulse sound of work
clamp. The machine is quiet even though the work clamp operates and in spite of it having a solenoid drive.
· With the adoption of the invertor motor, the motor will be stopped while sewing machine is stopped.
6. Improved durability

· Each mechanism, like the feed and thread trimmer mechanisms, has been simplified. Both durability and liability so 1----l-----+--+---+--=---lfH---l---~
have been improved.
7. Common gauge parts
• Gauge parts like the work clamp and feed plate can be used on the LK3-B430, as well. (See page 1 0.)
8. Others
• Conventional subdivided specifications have been reduced to four specifications to facilitate understanding.
(See pages 8 and
9.)
• Safety mechanisms are installed on this machine. Operatorcan work safely and comfortably.
• Operation panel is designed for simplicity and easy understanding. With simple operation, work efficiency will
be further increased. (See page 6.)
• The machine head has· been lightened to 47kg, and it is positioned on the table top. Installation can be per-
formed easily.
• Air is no longer used.
• To prevent thread from getting dirty when sewing knitted materials, the exclusive large shuttle hook is equipped
as a standard part. (See page 1
0.)
• A switching regulator (for stabilizing power supply) has been adopted, and consequently sewing operations will
not usually be affected by voltage fluctuations. However, if the voltage drastically fluctuates, the machine will
stop and display an error code. (See page 15.)

B430E makes sewing operation efficient since the sewing pattern is changed easily by just pressing a button. Also, it offers flexibility to rearrange the process organization.
<Example>
Since a process that previously required two machines due to the different number of stitches can be performed on only one machine, the time taken to convey work pieces be-
tween the
two machines has been eliminated, thus increasing productivity.
It is more efficient to use a handy switch (optional part). See page 12 for handy switch.

• Program list
· There are twelve standard sewing patterns on the
LK3-B430E. Programs
Nos. 1-9 are identical to
those
of the LK3-B430. Programs Nos. 10-12 are
newly designed for the B430E.
• For each specification, sewing patterns are limited
as shown in the right table. (Any program is avail-
able
as long as the sewing pattern is within the
work clamp
and feed plate in size.)
These program numbers are equal to those for the
LK3-B430 lockstitch bar tacker.
• Programs No.1 0-12 are for straight tack stitches.
· If you want to sew a pattern other than one of the
standard
12 patterns, you can create your original
pattern using the BAS-PC/300. (See page 12.)
Consult with your local Brother Sales Office for
details.

· Handy switch
B430E can register up to 6 sewing patterns in addition to the standard sewing patterns, Nos.1-12.
These patterns are sewing patterns that are created by enlarging or reducing the size
of standard pat-
terns.
Using the handy switch, 6 patterns
can be retrieved from the registered patterns. l.t will be useful to in-
crease productivity since sewing patterns
can be changed with a workpiece lefton the machine.
Make sure that the sewing pattern
is within the dimensional limits of the work clamp and feed plate.
· Two-pedal foot switch
The single-pedal foot switch is standard equipment. With the two-pedal foot switch, one pedal is used
to liftthe presser foot, the other being for starting sewing.

• DIP switch
1. DIP switch on the circuit board in the control box
The DIP switch in the control box is used for setting functions that are least likely to have their mode changed.
Switch Motion when set to
ON
DIP B-1
First two stitches are sewn at a low speed of 260 spm.
DIP B-2
Last two stitches are sewn at a low speed of 260 spm.
DIP B-3
Last two stitches are sewn at a low speed of 400 spm regardless of the pattern.
SEE NOTE
DIP B-4
Last two stitches are sewn at a low speed of 700 spm regardless of the pattern. SEE NOTE
DIP B-5
This is used for checking circuit board. Be sure to set to OFF.
DIP B-6 Low speed sewing
is not performed at the start of sewing.
DIP B-7
-
DIP B-8
This is used for future specifications. Be sure to set to OFF.
NOTE: Last two stitches of sewing pattern No. 2, 3 or 6 will be sewn at 700 spm for denim specification;
otherthan those, about 400 spm will be set automatically.
2. DIP switch on operation panel

3. Setting work clamp motions
Through the combination of DIP switches A-1 and A-2 on the operation panel, work clamp motio ns ca n be set as follows:
DIP A-1 DIP A-2
--Single pedal Work clamp is raised automatically.
ON -Single pedal Work clamp is raised by pressing the pedal.
-
ON T wo pedals Work clamp is raised automat ica lly, then it is lowered by pressing the pedal.
ON ON Two pedals Work clamp is kept lifted while the pedal is pressed.
• Memory switch
Memory switch fun ct ions a re stored in the EEPROM chip on the main ci rcuit board.
These function settings are able to be
chan ged according to sewing requirements, however, most of
them are not oft
en u se d.
