Stitch Regulator – Methodical Check
1. Usually start with theory of how the Regulator works and what it will and wont do.
2. Check the mechanical things to make sure installed and connected correctly.
3. Have them unthread the machine all the way – place the spool on another table
and remove the bobbin case.
4. Make sure the regulator is activated correctly.
5. Make sure they are hitting select the 2
nd
time to fully activate the regulated mode.
6. Have them check if the machine will do about 3 or 4 stitches and stop in regulated
mode if the machine is not moved. (Have them hit start and not move)
7. Ask them how many stitches they think the machine will do if they just stop moving
in Regulated Mode (It will also be about 3 or 4). Make sure they understand why
the machine sews a few more stitches if they just stop moving the machine and
that if they want to stop fast they must hit the stop button.
8. Have them move slow like a snail from front to back and gradually speed up –
does the machine sound like it is responding to their increase and decrease in
speed? Ask them if it is responding?
9. Do the same check left to right. Can you hear the machine responding to their
speed? Ask them if it is responding.
10. Have them do a 10” circle – listen and determine if the machine responds to both
encoder wheels at the same time and respond to their speed? Ask them if it
responded.
11. Have them move too fast so the see and hear what the machine does when it
goes into “Overspeed Mode”.
If the machine will do these things then it will respond to the regulator.
