８-８. Setting the work clamp mode
Through the combination of DIP switches A-1 and A-2 on the operation panel, presser motions can be set as follows:
[Setting solenoid work clamp mode]
DIPA-1 DIPA-2
Pedal specifications
Raising the presser at the sewing end
- - Single pedal
Work clamp is raised automatically. (factory default
settings)
ON - Single pedal Work clamp is raised by pressing the pedal.
- ON Two pedals
Work clamp is raised automatically, then it is lowered by
pressing the pedal.
ON ON Two pedals
Work clamp is kept lifted while the work clamp pedal is
pressed.
[Setting pneumatic work clamp mode]
memo-42=0 (memo-3b=0: KE-436B, 436C) <initial value>
DIPA-1 DIPA-2
Pedal specifications
Raising the presser at the sewing end
- ON Single pedal Work clamp is raised automatically.
ON ON Single pedal Work clamp is raised by pressing the pedal.
- - Two pedals
Work clamp is raised automatically, then it is lowered by
pressing the pedal. (factory default settings)
ON - Two pedals
Work clamp is kept lifted while the work clamp pedal is
pressed.

specifications
Raising the presser at the sewing end
5 Two pedals
Left presser drops when presser pedal is at the 1st step, and right presser drops
when presser pedal is at the 2nd step.
Raising is carried out in the reverse order.
* Initial value for inner clamping specifications only
* Setting used when using the light work clamp function (Refer to “1-8-3. Light
work clamp”.)
6
Two pedals
Right presser drops when presser pedal is at the 1st step, and left presser drops
when presser pedal is at the 2nd step.
Raising is carried out in the reverse order.
7
Two pedals
The left/right operating sequence changes alternately for each item sewn when
using two-pedal operation.
Starts with right left.
8
Three pedals
(Option)
The left pedal is used to raise and lower the left presser, and the right (center) pedal
is used to raise and lower the right presser.
The start (right) pedal is used to start sewing.
Furthermore, when DIP switch A-2 is at ON, and if one presser is already lowered,
pressing the start pedal causes the other presser to be lowered and then sewing
starts.
9
Two pedals
When the presser pedal is depressed to the 1st step, both left and right pressers are
raised simultaneously.
When it is pressed to the 2nd step, sewing starts.
10
Two pedals
When the start pedal is depressed, both left and right pressers are lowered
simultaneously.
When the start pedal is released, sewing starts.
11
Three pedals
(Option)
The left pedal raises and lowers the left and right work clamps, and the right pedal
(center) detects the home position. The start (right) pedal is used to start sewing.
For the stepping foot specifications, both work clamps are lowered when DIP switch
A-2 is ON, and the stepping foot is also lowered at the same time.
12
Three pedals
(Option)
The left pedal raises and lowers the left work clamp, and the right pedal (center)
detects the home position. When the start pedal (right side) is depressed for a short
time (200 ms), the right work clamp is lowered, and when it is depressed for a longer
time the right work clamp is lowered and then sewing starts.
For the stepping foot specifications, the right work clamp is lowered when DIP switch
A-2 is ON, and the stepping foot is also lowered at the same time.
13 Two pedals
Two-pedal operation raises and lowers the left and right work clamps
simultaneously, and the stepping foot is lowered at the sewing start.
When memo-42 (memo-3b) has been used to make a special setting, DIP switches A-1 and A-2 function as follows.
When DIP switch A-1 is at ON, the work clamp are not raised automatically at the sewing end.
DIP switch A-2 is ignored except when memo-42 (memo-3b) = 8, 11, 12.
