5. Replace the cover and the three screws except the one
over the "IN" tube fitting. Leave this screw loose enough
to turn tube fitting for adjustment. NOTE: To obtain
maximum tube life, the tube assembly must ride in the
center of the rollers. To center the tube assembly on the
rollers, set the feed rate dial on #10, turn the feeder on,
turn the "IN" tube fitting not more than 1/8 of a turn in the
direction which the tube must move. Observe the tube
assembly. It should move toward the center of the rollers.
If the tube moves further from the center of the rollers,
turn "IN" tube fitting in the opposite direction until the
tube centers. Turn the feeder off and tighten the tube
housing cover screws left loose.
