USING THE AUTOFEED The mechanical autofeed mechanism works the same for all configurations of the Goliath Guillotine. Use this procedure to engage and disengage the autofeed when cutting with the saw. The autofeed is driven from the cam wheel that moves the saw bow for cutting.
Goliath Guillotine Pipe Saw Trip pin Cam wheel Feed screw Chapter 5: Operating Instructions Feed worm Feed shaft Feed worm gear Figure 5-13. The photo shows the feed drive components. When the autofeed is disengaged, the feed screw turns freely and does not move the bow. Engaging the autofeed locks the feed screw, allowing the feed worm gear to index the bow into the workpiece with each revolution of the wheel cam. The feed rate is approximately 0.008” per saw cycle.
Chapter 5: Operating Instructions Goliath Guillotine Pipe Saw Secondary trip pin Primary trip pin Figure 5-14. To double the feed rate, use a pliers to pull the secondary trip pin down until it snaps into place. Slide it back up into the cam wheel to set the feed rate back to the standard speed. 1. Make sure the autofeed is disengaged when starting the saw motion. The feed lockout pin will be pushed in to disengage the feed. Figure 5-15.
