Hook Point
The eye of the needle should be just below the point of the hook(b,c). The eye should look like a teardrop
hanging from the point of the hook. If the eye is above or below, the needle bar may need adjusting. If the
needle bar is too high, the loop will be formed above the hook point : too low, and the loop will form below
the hook point. In both cases, skipped stitches will result. Needle bar height (a) rarely changes unless you
crash a hoop. If one needle on a head is skipping stitches, needle bar height is most likely the culprit. If all
are skipping, check the hook timing. Before you do anything change the needle, check the thread path and
clean the bobbin case.
Hook Point
0.1~0.3mm
The point of the hook should be directly behind the
needle. The gap between the point and the scarf of
the needle (indentation on the back of the shaft)
should be between 0.1 and 0.3 mm. A good test is to
run a piece of paper between the needle and point of
the hook. One piece of paper should fit with no
deflection. Two pieces of paper, however, should
deflect the needle. This measurement is important
because if the hook passes too close to the needle,
broken needles can result as well as broken thread
and damaged hooks. If the hook passes too far from
the needle, skipped stitches may result, as the hook
point may not penetrate each loop that is formed. lf it
is far enough away, there will be no stitches formed
at all.
