ADJUSTING THE REAR PULLER DEVICE
14-1 Manual lever and position of the stopper
To position or remove the fabric, raise manual lever
A. With the manual lever lowered, hold stopper B
so that the clearance between the upper and lower
pullers is 0.5mm. Then tighten nut C.
14-2 To adjust the puller pressure
The puller pressure should be as light as possible,
yet be sufficient to feed the fabric smoothly.
To increase the pressure, turn adjusting knob D
clockwise. To decrease the pressure, turn adjusting
knob D counterclockwise. Fasten the lock nut E
after adjusting.

by changing of the movement amount of the upper
roller in order to meet the sewing fabric and the
sewing conditions. To decrease the amount, loosen
nut F and move it up. To increase the amount,
loosen nut F and move it down.
If the feeding amount is too large or small, remove
the rubber plug G and loosen the nut H.
