The movable needle guard 1 should hinder a deflection of the needle
into the path of the hook.
When the hook tip moves to the left and reaches the needle, the
needle guard automatically swings toward the needle. In this position
the needle must touch the needle guard.
The movement timing of the needle guard cannot be altered.
Caution Risk of Injury!
Before adjusting turn the machine off.
–
Turn the machine in the direction of run so far that the hook moves
to the left and has reached the needle.
–
Loosen the lock nut 3 and, with the threaded screw 2, set the
needle guard so close to the needle that it does not let itself be
pressed into the area of the hook.
The needle may not be deflected more than necessary.
The purpose of the needle-guard plate is to prevent the needle from
being deflected when it picks up the loop and to open the thread loop
behind the hook.
When the hook tip moves to the left and reaches the needle, it must
not be possible to press the needle against the direction of sewing.
–
Undo screw 6.
–
Adjust the needle-guard plate 4 so that the needle 5 passes freely
between the hook and the needle-guard plate.
–
Tighten screw 6.
