INTRODUCTION Oliver’s Size Right model # 1 PD utilize a cogged timing belt, designed to accurately size seed by width (using round hole cylinders) or by thickness (using slotted hole cylinders). The following instructions apply to Oliver’s Size Right #1 PD. The drawings in this manual are representative of the Size Right #1 PD.
INSTALLATION 1. Remove the Sizer from the shipping crate. Check and remove any packing material & spare parts from the machine. 2. Place the Sizer in a desired location, allowing a minimum of two feet on each side for the removal of cylinders. NOTE: Make sure the Sizer is level across its width.
BASIC OPERATION 1. All seed should be cleaned prior to sizing. 2. Dispense seed into the feed hopper located on the top of the machine (See Diagram 1-A). 3. As the cylinder (See Diagram 1-B) rotates, smaller seed (“thrus”) drops through the cylinder openings (See Diagram 1-C) as the larger seed (“overs”) continues down the length of the cylinder, discharging over the end (See Diagram 1-D).

START-UP Before turning the machine on, make sure the cylinder is locked into place and there is a tight fit between the intake hub and the felt seal. Make sure all doors are in place and locked with the special key. This key prevents access to the cylinders while the machine is operating.
