Operation Manual

Mounting the cutting block at the top or bottom ?

The mounting of the cutting block

and the cutting knife

is dependent on the

sub-class with its sewing device (E no.) for cutting "before" or "after sewing":

A. Sewing device for "cutting before sewing":

–

Cutting block at bottom and cutting knife at top

–

The material is supported by the cutting block during the cutting procedure.

In this way an unwanted pressing down of the edges of the buttonhole slit by thick

material (as in configuration b) is avoided.

Attention !

With the cutting knife mounted at the top the waste pipe 3

for collection of cutting waste must be mounted on the

cutter bar 4.

B. Sewing device for "cutting after sewing":

–

Cutting block at the top and cutting knife below

–

The sewn buttonhole seam glides down the slim sides of the cutting knife without

resistance during the cutting procedure.

In this way an unwanted deformation through pressure exerted on the buttonhole

seam (as with configuration a) is avoided.

C. Sewing device for "cutting before and after sewing":

–

Cutting block at the top and cutting knife below

–

Exception:

With the setting "cutting before sewing" and at the same time processing of thick

material the reverse configuration (cutting block at the bottom and cutting knife

above) is to be chosen.

In this way an unwanted pressing down of the edges of the buttonhole slit (as with

configuration b) is avoided.

ATTENTION !

For the change-over from "cutting before sewing" to

"cutting after sewing" it is essential to obderve Chapter

2.19.
