2.3 Machine Requirements Your Castle AT-8 Open Back Face Frame Assembly Table requires a minimum of 85 PSI air not to exceed 150 PSI. Supply Line should be a minimum of ¼” line. Install an air filter trap to reduce the potential for foreign particles and water from your air supply prior to entry into the machine. The filter should be mounted to the wall where your supply comes from and SHOULD NOT be mounted to your machine. 2.
3 Setting Up Your AT-8 Open Back Your Castle AT-8 Open Back Assembly Table is shipped knocked-down, with the legs bolted to a pallet and the frame and top inside. 3.1 Frame Assembly 1. Remove the clamp arm from the pallet by cutting the two zip ties. 2. Unbolt the legs on the narrow side of the pallet and open them to an almost parallel position. 3. Remove the packing envelope.
9. Position all three joining plates [G08513 & G08512] and bolt loosely in position using 3/8-16 x 1” bolts [F38161], 3/8 Nuts [F38168] and 3/8 washers [F03876]. 10. 11. Using the pictures as guide, clamp the joints at the top and bottom of the frame. Make these joints as flush as possible. Keep in mind that the bearings for the clamp arms are going to roll along this joint. 12. Tighten top and bottom joining plates first, then tighten all the plates.
13. Attach the legs and leg braces 14. To attach each leg you will need: a. (2) leg braces [G08516], b. (6) 5/16-18 x 7/8” hex head bolts [F51878] and c. (6) 5/16-18 hex nuts [F51628]. 15. Have someone hold the leg while you fasten it to the frame. The flat part of the angle iron should face the inside of the machine. 16. Attach the (2) leg support bracket using bolts supplied. Repeat this process for the other side. 17.
3.2 Fence Installation 1. Attach the fences using the ¼-20 Flat Head bolts [F44134], aluminum spacers [N00345 and N00346] and the ¼-20 Kep Nuts [F01422]. The side fence uses the small spacers and the bottom fence uses the larger spacers. Caution: When fastening the fences be sure to only tighten one bolt on each fence at the bottom left corner of the frame. You will tighten the rest later. CASTLE, INC AT‐8 OB OWNERS MANUAL V2.
3.3 Worktop Installation 1. Place the table top onto the frame, make sure the top is sitting as far left as it will go and flat on the bottom. 2. Starting with the top swing the left top onto the spline. 3. Push together tightly from right side CASTLE, INC AT‐8 OB OWNERS MANUAL V2.
4. Install draw bolts [F14312]. 5. Using the (30) #10 X 2-1/2” pan Phillips sheet metal screws [F10212] fasten the table down through the rear of the frame. 6. Place a sheet of plywood measuring AT LEAST 4’ x 8’ on the table, and rest it on the bottom fence. 7. Push up on the end of the fence opposite the end with the tight bolts until the fence is flush with the wood. Now tighten all of the bolts for the fences. CASTLE, INC AT‐8 OB OWNERS MANUAL V2.
3.4 Open Back Beam Installation 1. Locate the two yellow brackets. Begin by placing the two yellow beam brackets on the end of the top beam of the table. The yellow brackets are left and right hand. Tighten set screws to secure in place. Slide the top beam through yellow bracket on one side of the table. Slide it just too far to one side so you may slide the bracket on in the next step. 2. Put on the yellow arm top bracket with the “Castle” facing the front of the table. 3.
6. Install the stop bolts through the holes in the back side of the top beam. The stop bolts are necessary to keep the arm from sliding off the beam. 7. Stop Bolt Pack Includes: a. (2) ¼ x 5/8 Hex Head Cap Screw [F14585] b. (2) ¼ Kep Nut [F01422] c. (2) ¼ Hex Nut [F01423] CASTLE, INC AT‐8 OB OWNERS MANUAL V2.
3.6 Connecting Air NOTE: Standard AT Upper Brackets are shown in this illustration. Air connection is the same for both machines. 1. The air regulator on the upper bracket is rotated 180 degrees for its protection in shipping. 2. To rotate the regulator and gauge, loosen the nut located on the outside of the bracket (shown) and rotate. 3. Use the ¼” OD X .17 ID x 16” Black Tube [P14170] included to connect air from the regulator to the push-in fitting at the top of the arm. 4.
5. To set the Air Pressure, pull the yellow knob on the regulator out and turn the knob until the pressure measures 85 PSI on the gauge. CASTLE, INC AT‐8 OB OWNERS MANUAL V2.
4 Operating Instructions Warning: Always wear eye protection when operating pneumatic equipment. 4.1 Cylinder Actuation To operate the clamp cylinder locate the black lever with the rubber stopper. Moving this lever back and forth will clamp and release the cylinder. Your Assembly Table beam arm is fitted with (5) ports for air fittings and can accommodate an optional fifth clamp cylinder. CASTLE, INC AT‐8 OB OWNERS MANUAL V2.
4.2 Screw Bowl Holder The Screw Bowl is held in place by the red lever on the Clamp Arm Bottom Bracket. Pull the lever down to release the bowl and push it up to hold the bowl in place. 4.3 Optional Screw Gun Airline Your Castle Assembly Table comes with a 3/8” AT Gun Hose Assembly [C08000]. To attach the Air Screw Gun (optional) remove the red plug from the regulator and connect the AT Air Gun Hose Assembly. Next, thread the hose through the aluminum arm.
5 Maintenance Note: Contact a Castle, Inc service technician for proper service information. It is suggested that the table top be periodically cleaned of excess glue and/or dust. The Poly Foot Pads are subject to wear over time and should be replaced. If you notice a considerable slow down in the speed of the cylinder actuation, the cylinder may need to be rebuilt using the AT Cylinder Rebuild Kits (Part #K08004).
6 Trouble Shooting Guide 6.1 Adjusting the Arm Bearings Your Assembly Table Arm rides on two sets of bearings; one at the bottom bracket and one at the upper bracket. If the arm becomes loose or rides on the beam roughly, these bearing sets may need to be tightened. This procedure is performed best with two people. 1. Loosen the four bolts in the top bracket that hold the arm in place while someone holds the bottom bracket firmly in place against the table. UPPER BRACKET ARM BOLTS BEARING NUTS 2.
6. If the bearings were loose, the tightening procedure could change the arm positioning. Test the positioning of the arm by rolling it along the beam. It should roll smoothly the whole way and be parallel to the tabletop. 6.2 Aligning the Arm When your Castle Assembly Table is set up or reassembled after relocation, the arm must be aligned to ensure proper operation. Note: This procedure requires two people. 1.
6.3 Tightening Bracket Bolts The bottom bracket is held to the aluminium clamp bar by two bolts. If either of these bolts is loose or slightly tweaked out of shape, the pneumatic seal won’t hold. It is important that these bolts be tight. LOWER BRACKET BOLT BRACKET ARM SEAL Warning: Bottom Bracket bolts are tapped directly into the aluminium. If they are overtightened they may strip out the arm. 1. Check that the bolts on the bottom bracket are tight. 2.
6.5 Tightening the PEM Nut Note: This procedure requires two people to remove the arm assembly from the table. The cylinder lever is held against the body of the cylinder with a PEM nut. If you notice that the cylinder lever has come loose or that your clamp cylinder does not hold pressure the PEM nut may have come loose. This nut can be tightened by first removing the cylinder and then tightening up the nut. 1. Turn off the air and remove the airline for the cylinder with the loose lever.
1. Turn off the air and remove the airline for the cylinder to be rebuilt. The line is connected to the cylinder by a push-in fitting. Push the outer ring in as you pull the airline out. 2. Loosen the tension screw on the side of the Cylinder Channel. 3. Remove the (4) Wear Strip screws on each side of the Cylinder Channel and remove the complete assembly from the arm. 4. With the cylinder off the arm remove the Snap Ring (#2) on Appendix A 5. Remove the piston (#1). 6.
