Setting The Cutting Width; Exchanging Needles - Silvercrest KH 4300 Instrucciones De Uso

Setting the cutting width

The appropriate cutting width is, from material to
material, variable. Each time test the seams and
adjust the cutting width as follows:
1. Turn the handwheel 6 towards yourself until the
needles are in the lowest position.
2. Open the front flap 8.
3. Press the lever PUSH f. The free arm 0 lowers
itself and the adjustment wheel for the cutting
width i can be seen.
4. Turn the djustment wheel for the cutting width i.
With this you move the lower blade p. Continue
turning it until the looper threads are lying at the
edge of the material. When you turn in the direc-
tion W (wide), the cutting width is broader.
When you turn in the direction N (narrow), the
cutting width is narrower.
Examples:
Select a narrower cutting width if the material edges
ruffle during sewing. For this, turn the adjustment
wheel for cutting width i to the right (N).
Select a larger cutting width if the yarn is being sewed
beyond the material edge. For this, turn the adjust-
ment wheel for cutting width i to the left (W).

Exchanging needles

Attention!
Before exchanging the needles, remove the power
plug. This prevents an unintended starting of the ma-
chine. If you do not, you run a risk of serious injury!
1. Turn the handwheel 6 towards yourself until the
needles are in the highest position.
2. Open the front flap 8 and lower the sewing
foot o.
3. Loosen the setscrew against the needle with the
Allen key from the accessories box and then re-
move the needle:
- upper left setscrew for the left needle
- lower right setscrew for the right needle.
4. Insert the new needle, with the flat side to the
rear, into the needle mounting. Ensure that the
needle is inserted as far as is possible. Secure
the needle by retightening its setscrew.
When the needles have been correctly fitted, the
left needle stands a little higher than the right needle.
If the needles have not been correctly inserted, stitches
will occasionally be left out when sewing.
This machine is equipped with needles of the type
H.Ax1 (Needle system 130H) (for household ma-
chines).
