11. Looper height
Before adjusting the looping stroke as well as the needle bar height
and particularly after needle breakage it is necessary to check the
correct looper height.
Use gauge 2 for checking the looper height.
Caution: Danger of injury !
Switch the main switch off.
Adjust the height of the looper only with the machine switched off.
Standard checking
When the gauge is put on the looper turrets, please observe the
following:
–
The drill-hole 1 of the gauge must be on top right.
–
The tip of the left looper must be under the edge 3 of the gauge.
–
The tip of the right looper must be under the edge 4 of the gauge.
–
The looper points must just abut on the gauge.
–
Remove the thread trimmer 9, the throat plate 10, the spreader
stops 5 and 8 as well as the spreaders 6 and 7 from the looper
turrets.
–
Bring the needle bar in position “up” by turning the handwheel.
–
Put the gauge 2 on the looper turret with the loopers inserted in the
looper turrets as far as it will go.
–
In this position the rules mentioned above must be fulfilled.
Correction
–
Adjust the correct looper height by slight alignment of the loopers.
