Two pedals Presser is kept lifted while the presser pedal is pressed.
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 "14-3.
Light work clamp".)
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.
The left/right operating sequence changes alternately for each item sewn
when using two-pedal operation.
Starts with right
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.
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.
When the start pedal is depressed, both left and right pressers are
lowered simultaneously.
When the start pedal is released, sewing starts.
