4.11 Loop stitching with economy 25/40
- Fig. 4.12 -
- Move the main slide bar -22- so that the axle -51- on the right side of the stitching head is acces-
sible. Do this using the hexagon socket screw key -5-, size 5 from the tool-set. Insert it in the cylin-
drical screw at the back of the drive motor and turn in the direction of the arrow, pushing the fan
lever -7- simultaneously.
- Relieve the roller tappet -52- with the holding clip -53-.
When changing the benders for "loop-stitching", it is essential to replace coarse.
- Pivot the leaf spring -19- and remove the finger guard -20-.
- Fine benders are required for loop-stitching. Remove coarse benders, right and left, and replace
them with fine benders, left -55- and right -56-. Loosen the hexagon socket set screw -57- in front
of the main slide bar using the round screw hook -54-, then pull out the axle -51- laterally.
- Now remove the shoe tongue backwards.
- Introduce shoe tongue -58- for loop-stitching from behind, push the axle -51- in again and
retighten the hexagon socket set screw -57-.
- Insert the driver -59- for loop-stitching and the switch finger -25-. Ensure that the switch finger is
screwed into the upper thread by the driver.
- Tighten both benders, left -55- and right -56-, securely. Both benders are now located close to the
lateral surfaces of the main slide bar -22-.
- Before switching the machine on, please turn the motor once by hand for a final check, than
relieve the roller tappet -52- with the holding clip-53-.
