5-6. Needle up/down compensation switch

1
5-7. ON/OFF switch
• When the material edge sensor, which is optionally available, is connected to the operation panel, the ON/
OFF switch of the material edge sensor becomes effective.
• If the material edge sensor is specified, the sewing machine will automatically stop running or perform thread
trimming when the sensor detects the material edge.
Cau tion
If the material edge sensor is used in combination with the operation panel, carefully read
the Instruction Manual for the material edge sensor beforehand.

5-8. Automatic thread trimming switch

• This switch is used to automatically actuate the thread trimmer in a process where the sewing machine
automatically stops or when the material edge sensor is used.
(if the automatic reverse stitching (for end) is specified, the thread trimmer will actuate after the sewing machine
completes the automatic reverse stitching (for end).)

5-9. One-shot automatic stitching switch

• This switch is used, in the step pattern , or in the process where the material edge sensor is specified, to make
the sewing machine automatically perform sewing at the specified speed until the end of the process is
reached only by driving the sewing machine once.

5-10. Thread trimming prohibition switch

• This switch is used to temporarily make the thread trimming function inoperative.
The other performance of sewing machine is not affected by this switch.
(If the automatic reverse stitching (for end) is specified, the sewing machine will perform the automatic reverse
stitching at the end of sewing.)
• If the automatic thread trimming switch
the machine will not perform thread trimming but stop with its needle up.

5-11. Key lock

• In order to prevent the specified data on the number of stitches or the processes (A, B, C and D, or step
information) from changing by mistake, the setting switch can be locked. (Even with the setting key locked,
the pattern to be sewn and the value on the bobbin thread counter can be changed.)
• For the setting procedure, refer to 5-13 Setting for functions and set function No. 17, Key lock function (key
lock is effective with setting of "1").
Every time needle up/down compensation switch
pressed, the needle goes up when it is in its lowest position
or comes down when it is in its highest position. This
compensates the stitch by a half of the predetermined stitch
length.
Note, however, that the machine does not run continuously
at a low speed even if you keep the switch held pressed.
Also, note that the needle up/down compensation switch is
inoperative after turning the handwheel by hand.
Thread trimming is operative only at the time of stitch
compensation after depressing the front part of the pedal once.
