1. Put on the disposable gloves. Open the white plastic tube and slide the ink roller out of the container onto a plastic bag or paper towel. Insert the hollow tube into the axle hole in the roller. The tube should fit so it is approximately flush with both ends of the ink roller.

2. Attach one acorn nut, finger-tight, to one end of the roller axle. Slip the free end on the axle through one of the handle bracket assembly arms until it protrudes about 1/2 inch. Slip a washer over the end of the axle.

3. Slide the roller onto the axle. Slide the axle through the roller until the threaded end is visible. Slip the remaining washer over the end of the axle. Note that the washer goes between the roller and the handle assembly arm.

4. Slide the axle through the second handle bracket assembly arm. Attach the remaining acorn nut to the end of the axle. Tighten both acorn nuts. Place the vinyl caps over the acorn nuts.

5. Prepare the roller for use by gently wiping the roller surface with one of the towelettes provided to remove areas of excess ink. Dispose of all packing materials and remove gloves. Use the remaining towelette to clean hands as necessary.
