    Appendices APPENDIX B: Jacq3G Lubrication Schedule This document provides information regarding lubricating the Jacq3G mechanisms. The points described below are intended for yearly lubrication. However, the one year periodicity is subject to the unique conditions that each loom encounters. For example, a loom in constant usage should be lubricated more often, perhaps even once per quarter.

  • Page 58: Appendix C: Jacq3G Module Troubleshooting And Adjusting Guide

    Appendices APPENDIX C: Jacq3G Module Troubleshooting and Adjusting Guide This document provides information regarding troubleshooting and adjustment of the Jacq3G hook modules. The points covered in this document address a very large percentage of potential issues and adjustments that the user may encounter. However, not all potential concerns are addressed by this guide.
  • Page 59 Appendices APPENDIX C: Jacq3G Module Troubleshooting and Adjusting Guide (continued) Test #1: Observe the solenoid plunger without power to the loom. Tap on the plunger. Does it spring out quickly and easily? Does it stick in or move sluggishly? If it does not spring out easily, then you have a misalignment issue. Proceed to Test 1a. Test #1a: Check plunger action of the hooks surrounding.
  • Page 60 Appendices APPENDIX C: Jacq3G Module Troubleshooting and Adjusting Guide (continued) Test #7: Observe the misbehaving hook in action. Is it frequently crossing over/under with a neighboring hook? Does it have abnormal movement side-side or front-back as it slides up and down through the guides? If so, it or possibly the adjacent hook is bad. Test #8: Observe the hook in action and listen carefully.
  • Page 61 Appendices APPENDIX C: Jacq3G Module Troubleshooting and Adjusting Guide (continued) Bad hook: Replace the bad hook. CAUTION: Make sure you do not accidentally drop the plunger spring onto the printed circuit boards while it is powered or you risk shorting the printed circuit board. Bad plunger spring: Replace the bad plunger spring.
  • Page 62 Appendices APPENDIX C: Jacq3G Module Troubleshooting and Adjusting Guide (continued) Lubrication: See Jacq3G Lubrication Schedule document. Knife alignment: 1) Knife angle: If the angle of a knife is observably different from the neighboring modules it must be remedied before any further loom use. Failure to do so will cause bearing failure.
