SYMPTOM POSSIBLE CAUSE PROBABLE SOLUTION

Warning! Inspect the machine on a regular basis and use only quality parts. The manufacturer

recommends using original AMF Reece parts, especially needles, loopers, spreaders, and throat plates.

1. INTRODUCTION

The S211 electronically displays error messages, when worn or damaged parts are detected. If machine

problems occur and the error is not displayed, ensure correct needle installation and threading. The other

troubles are eliminated according to the detailed descriptions listed.

Adjustments Quick Reference List

Note: Required machine settings are variable according to the fabric and thread variations used. The type

of thread and fabric will affect the amount of wear on machine parts. The components marked in yellow

are set by manufacturer and do no require further adjustments. Changing the position of components

marked in yellow, without the approval of the manufacturer, may cancel the warranty.

To obtain the highest quality buttonhole maintain the following values:

- clearance between the needle and the loopers is 0.05 to 0.1 mm, (0.002 to0.004”)

- clearance between the needle and the needle support is 0.05 to 0.1 mm.

- the same distance of the left spreader tip and the right spreader tip when they pass the needle.

- left looper on the centre of the needle when the stroke is 3.4 mm from the lowest position.

- with the needle bar in the lowest position, the axial clearance is 0.25 mm, (0.010") when the pressure

power is 5N

- with the needle bar in the lowest position, the radial clearance is 0.05 mm, (0.002") when the pressure

power is 5N

- looper holder axial clearance is 0.05 to 0.1 mm, (0.002 to 0.004”).

- looper holder radial clearance is 0.1 to 0.2 mm (0.004 to 0.008”).

- looper holder angular clearance is 1.2 on the arm 28.5 mm when the pressure power is 5N.

- distance between the flags and sensors BQ1, BQ2, BQ3, BQ8 to 0.5 mm on the sensor BQ4 to

0.3 mm.

- air pressure regulator set to 0.45 MPa.

- BQ1 is activated when the needle bar raises 22 mm above the lowest position

- BQ8 is activated when the needle bar raises 32 mm above the lowest position
