- 47 - Check the Knife Fore/Aft and Up/Down Positions. Adjust the height by moving the drive lever in its bearings. The fore/aft direction is adjusted using screw joint A, fig. 55. The up/down position is correct when the bottom surface of the first knife section brushes the cutting surface of the knife finger. The fore/aft position is correct when the knife tang and the joint fixing piece can move freely for the whole length of the stroke without brushing the edges of the groove or the heads of the locking screws on the knife finger. Make sure the knife moves lightly when turning the table auger drive pulley by hand with the table disengaged. Replacing and Aligning of a Knife Section Remove the knife section by knocking out the rivets according to Figs. 56 and 57. Rivet up a new knife section. Use a riveting core to tighten the section to knife tang 1 and shape rivet head 2, fig. 58. Tool R 127831. |
