    6 a. Adjusting the Motor Belt Tension NOTE: The motor belt tension need not be tightened as tightly as the main timing belt (see 6 c.) Check the belt tension for tautness by pressing it with the index finger (see Figure 6.1). Proper belt tension provides for some belt flexibility under light finger pressure, but should not be so tight as to bind the machine.

    6 b. Adjusting Transmission Gear Lash (play) Check the transmission gear lash, between the metal transmission gear and the delrin hook shaft gear. NOTE: Do not adjust this unless you are sure it needs adjusting. This will affect the timing of the machine. There should be little or no lash between the two gears.

  • Page 21: Adjusting The Timing Belt Tension

    6 c. Adjusting the Timing Belt Tension Check the timing belt for tautness by holding the transmission pulley and rocking the hand wheel. You should not be able to feel play between the belt teeth and the transmission timing pulley teeth. NOTE: if you tighten the belt too much you will create a bind or extra noise in the machine.

    8. Needle Position, Check, & Adjustment Tools required: 2mm, 3mm handle allen The needle position adjustment is the most important of all adjustments in the machine. Needle Position provides the foundation for which all other settings are made. Once the needle position has been completed, great care must be maintained to keep this setting.

  • Page 25: Adjustment Of The Loop Lift And Needle Distance

    9. Adjustment of the Loop Lift and Needle Distance “Loop Lift” is a universal hook and timing term for all lock stitch sewing machines. When the needle lifts a specified distance from the BDC (bottom dead center), the hook point is set to coincide with the needle as shown in figures 9.4 and 9.5 Tools required: (loop lift clamp, part no.
  • Page 26 9 Adjustment of the Loop Lift and Needle Distance Continued Rotating basket down - Note: With the bobbin case basket in the normal position, the basket needle guard deflects the needle and makes it difficult to accurately adjust the needle distance between the hook point and the back of the needle scarf.

    11. Adjustment of the Stop Finger Tools required: (2.5mm handle allen) Check: The engagement of the Stop Finger and throat of the bobbin case support basket must have a clearance of 0.8mm to 1.0mm. (This clearance ensures that adequate space exists for thread escapement during the sewing process).
