Fig. 38: Setting the lifting gap
Setting steps
1. Loosen the screw (3).
2. Push the cover (2) downwards.
3. Loosen the setscrew (1).
4. Set the spool housing lifter such that the gap between the nose of the
spool housing and the recess in the throat plate is just big enough to
allow the needle thread to slip through without a problem.
While doing so, ensure that the gap is not so big that the middle part of
the hook swings to and fro, hitting the recess in the throat plate.
5. Tighten the setscrew (1).
6. Push the cover (2) upwards.
7. Tighten the screw (3).
11.2 Setting the point in time of opening
Proper setting
The spool housing lifter starts to open exactly at that point when the hook
tip is located below the spool housing lifter after the loop is taken up.
In 1-needle machines, this happens when the handwheel position is
(1) - Setscrew
(2) - Cover
(3) - Screw
(4) - Spool housing lifter
WARNING
