Step 1: To install the chair "stem" (arm assembly) measure and mark to the proper spacing as indicated on the approved layout drawings.

Step 2: Once all locations are marked, install the chair stems on the rail and tighten with a 13mm socket.

NOTE: It may be necessary to loosen the bolt to place it onto the rail, take care to not remove the bolt completely.

Step 1: Place the back on the seat, upholstery-to-upholstery. Take care to not snag the seat fabric with the back wings.

Step 2: If the back wings do not line up with the lower bolts loosen the steel wings using a torque wrench fitted with a 5mm Hex Socket or Allen wrench. Slide the wings in / out so they line up with the lower bolts taking care to make sure they are spaced evenly so the back is centered properly. Tighten the wings to 13 ft/lbs.

Step 3: With the wings resting on the lower bolts, rotate the back upward and line the upper holes in the back wing with the holes in the stems. Thread the pan head screws through the wings into the stems and tighten with the torque wrench to 13 ft/lbs.

Step 4: Tighten the lower bolts to 13 ft/lbs.

NOTE: To avoid stripping bolts, be careful to not over-tighten them. In addition, avoid pinching the wire harness that extends from the bottom of the back.
