-
Loosen rear jam nut (Figure 25).
-
Adjust forward jam nut to compression spring to 112 mm (4-7/16 inches).
-
Tighten jam rear nut.
-
Repeat steps 3 through 5 at the other side of the machine.
-
Measure the distance between center points of the belt-roller shafts at each side of machine to ensure that the measurements are equal (Figure 26).
Equal distance measures approximately 895 mm (35-1/4 inches).
Replacing the Conveyor Belt
Preparing to Machine
-
Empty the hopper.
