13. Setting the lateral clearance to the left needle
Requirement:
When the lower overedge looper 2 is at its left point of reversal, the gap to the needle “R1” must be 2.8 -
3.1 mm (fig. 24).
Check:
● Turn the handwheel in the normal direction until the looper is at its left point of reversal.
● Check the clearance using the adjustment gauge (measurement D).
Note:
The looper-to-needle clearance can be offset when the screw 5 is loosened.
For this reason the screw 5 may only be loosened slightly.
Setting:
● Turn the handwheel in the normal direction until the looper is at its left point of reversal.
● Slightly loosen screw 5 on looper lever 6.
● Set the lateral clearance of 2.8 mm by moving the looper lever 6.
● Tighten screw 5.
Test:
● As described under “Check”.
● After having set the lateral clearance, the
looper-to-needle clearance must be reset and/or
controlled as described in section 12 of the
adjustment and repair instructions.
