Needle protection
Standard checking
The needle protection 1 avoids that the needle 4 is deflected into the
path of the hook tip 5.
Before the hook tip 5 reaches the needle, the needle point must abut
on the needle protection 1.
It must not be possible to push the needle into the path of the hook
tip 5.
When the hook tip is at the level of the middle of the needle, there
must be a distance of 0.1 mm between the hollow groove of the needle
and the hook tip 5.
Caution: Danger of injury !
