E - STANDARD MACHINE ADJUSTMENT
5. THE SEWING MECHANISM HEIGHT CONTROL
Before any other adjustment, we recommend to check, if the height of the sewing mechanism of the
loopers, spreaders and stitching plate is adjusted properly.
5.1. The height 6,5 mm of the sewing mechanism support ➊, from the surface for the anvil can be
readjusted by inserting or removing the washer ➋ under the bearing flange ➌. The support is
decreased, if the washer is added - in B direction, if the washer is removed, the support is
increased - in A direction. The washers are supplied with the thickness 0,1 (19.0019.6.405) or
0,2 mm (19.0019.6.404). The adjustment can be checked with the sliding gauge - 10 mm from
the top edge of anvil base to ∅ of the bung .
5.2. After inserting the stitching plate, it is necessary to check the distances between the top edges
and the top surface of the clamp plates ➎. This distance is adjusted at the factory with
the screw ➏ under the stitching plate for 0,1 — 0,15 mm. The screwis secured with the
LOCTITE 243.
5.3. For above mentioned distances, the factory provides the height of the fitting plates surface ➒
from the surface to the anvil ➓ in lange 33,5 -0,2 mm.
