Adjustment
If the straightness of the color change feed screw exceeds 0.010” [0.25mm] it must be replaced follow-
ing procedures shown in this manual.
Color Change Housing Location
Measurement
1. The measurement of the color change housing location is done in reference to the top inside edge
of the upper v-rail.
2. The squareness of the location is the difference between the perpendicular measurement of the
distance from the left front and right front edges of the color change housing base to the inside
edge of the v-rail.
3. The location of the color change housing assembly should be no more than 0.010” [0.25mm] out
of square (difference between the left- and right-side measurements).
Adjustment
1. To adjust the location of the color change housing assembly, loosen the screws on the base of the
assembly just enough so that you can move the assembly.
2. Position the assembly to obtain the required squareness and then re-measure the color change
housing location. After adjusting the squareness of the color change housing it needs to be
checked that the take-up lever drive gear still clears all 16 take-up levers. Should this not be the
case the drive gear needs to be readjusted.
3. When the location is square to less than 0.010” [0.25mm], tighten the mounting screws to torque
specifications.
Bobbin Tension
Measurement
Using a Gauge pull the thread slowly until the bobbin starts feeding this should happen between 22 to
25grms/force or 220 to 250mN. This is tighter than the tension typically set for bobbins on other embroi-
dery machines.
The following procedures below approximates this tension specification for technicians who do not have
thread tension measurement devices in the field and should be used to check bobbin tension on the machine.
