3. Guillotine Pipe Saw Autofeed Supplement Set Up and Operation Supplemental Instructions Guillotine Pipe Saw Autofeed System NOTE This supplement replaces the instructions on pages 16 17 of the Guillotine Pipe Saw manual part no 03 MAN 01 Revision 3 The Guillotine autofeed is a hydraulic system that automati cally operates the feed drive from the saw s cutting motion drive The autofeed hydraulic system is self contained and is separate from the saw s hydraulic power source The autofeed is driven by a cam wheel on the saw s rotating shaft The cam on the wheel strikes a feed plunger on the autofeed system driving a hydraulic cylinder that rotates the saw s feed screw Figure 1 is a photo of the system The components of the autofeed system are illustrated in Figure 2 Figure 1 The photograph shows the autofeed system on the Guillotine saw The feed handle has been removed for autofeed operation In This Chapter AUTOFEED SYSTEM COMPONENTS AUTOFEED DRIVE SPECIFICATIONS CHARGING THE HYDRAULIC SYSTEM OPERATION E H Wachs Company Part No 03 SUP O1 Rev 0 1105 Set Up and Operation Guillotine Pipe Saw Autofeed Supplement The components are listed here by Ay the reference num bers in Figure 2 These num bers also correspond to the bill of materials in the Guillo tine user manual If you have the printed version of this supplement you will find that the final page
