6.6 Using the timing gauge
6.5 Distance between the needle and the looper
The distance
L
between the looper tip and the center of
the right needle differs according to the needle distance
when the needles are at the lowest points and the looper
① is at the extreme right.
Refer to Table 5 and loosen the screw ② of the looper
holder to adjust the distance.
The distance
L
can be adjusted easily by using the timing
gauge (No. 95220).
The gauge is a special order part. Place an order with our
agents or directly with us, if needed.

distance.
Move the looper to the extreme right. Keep fitting the
right needle into the V-shaped groove according to the
needle distance, and fit the looper tip to the gauge. Then,
tighten the screw ② securely.
