9.1 Clearance of the Transport Clamps to the Folder Sole

50
There must be a specific clearance between the outer edges 2 of the
folder sole and the inner edges 1 of the transport clamps. By
medium-weight ready-to-wear material it must be e.g. 1 to 1.5 mm.
The clearance is necessary in order to assure uniform piping widths on
both sides and an unimpaired transport of the material.
Both transport clamps are set by turning the Allan screws 7.
The scale plates 5 serve as setting aids.
Caution Risk of Injury !
Turn the main switch off.
Set the transport clamps only with the main switch turned off.
–
Turn the Allan screw 7 for setting the clearance. To turn use the
Allan key 8 to be found in the accessories pack.
–
The scale plates 5 are aligned at the factory as follows:
When the pointer 6 indicates the marking " I " , the correct
clearance is set for medium-weight material when sewing pocket
openings with piping on both sides.
The second marking indicates the clearance for sewing a greater
piping width or a pocket opening piped on one side.
–
By stepping forward and back on the left pedal conduct test runs
with the transport carriage.
The transport clamps must pass the guide plates 4 and the thread
catcher 3 unimpaired.
ATTENTION !
The markings on the scale plates 5 are matched with the needle
spacing of the machine head.
When inserting needle holders for different needle spacings, the scale
plates 5 must also be replaced.
