ASSEMBLY

REFER TO PARTS LIST DIAGRAM

1. Unpack the product and check the contents. Should there be any damaged or missing parts, contact your supplier immediately. Take care to ensure safety when removing main frame from its packing, as the unit is very heavy.
2. Use the parts diagram as your guide to assembly. Lay all parts and assemblies out before beginning assembly. The following procedure is recommended.
3. Attach one base section (21) to the left frame post (20) and lower cross member (26) using bolts (25), washers (22), lock washers (23) and nuts (24). Attach two diagonal supports (60) between the post and base section using bolts (25), washers (22), lock washers (23), and nuts (24).
4. Attach the other base section (21) and the right frame post (20) to the lower cross member (26). Attach two diagonal supports (60) between the right post and base section using bolts (25), washers (22), lock washers (23), and nuts (24).
5. Put the press frame in an upright position, attach one upper crossbeam (10) to left and right posts (20) using bolts (9), washers (13), lock washers (12), and nuts (11).
6. Hook the under plate (7) onto the first cross beam and slide the other crossbeam sideways through the other hooks until it is in position in front of the posts. Attach to the posts with bolts (9), washers (13), lock washers (12) and nuts (11).
7. Screw the upper round nut (6) onto the ram (3), insert the ram into the hole in the under plate (7), then screw the lower round nut (8) onto the ram and attach the serrated saddle (5) to the ram.
8. Place the two halves of the press bed frame (18) back to back. Move them apart until the space between them is the same as the length of the four spacers (28). Align each spacer with the holes in the bed halves and insert a bolt (27) through both frames and the spacer. Secure the four bolts by using the washers (14), lock washers (15) and nuts (16).
9. Insert bed frame pins (19) into the holes in the posts at the same level. Hold the assembled bed frame diagonally between the posts. Turn it horizontally so that the ends are in contact with the posts and lower it onto the pins.
10. Attach the pump and air motor assemblies to the right post using bolts (29) and washers (14). Ensure that the air motor is below the pump. Insert the pumping handle (48) into the handle bracket (38).
11. Connect the hydraulic hose fitting (57) to the connection nut (58) and assemble the pressure gauge (1) to the pressure gauge connection nut and nylon ring (59) (2) which is on the top of the ram (3).
12. Tighten all nuts, bolts and screws.

INSTALLATION

DANGER! The press is top-heavy. If it requires moving after assembly or for relocation, use suitable slings around the top crossbeam, or lift direct with a forklift with the forks located under the top crossbeam. DO NOT use a pallet truck.

1. Securely attach the press to a flat, firm, level surface, taking into account any clearance required for workpieces.
2. Connect to an air supply as recommended in fig.1. The air supply must be capable of 108 to 120psi and 4cfm.
3. Purge hydraulic system. Before operating the press, the hydraulic system may require purging in order to eliminate any air that may have built up during transit.
4. Manual operation: open the release valve by turning it counter-clockwise. Pump several full strokes to eliminate any air in the system.
5. Air operating system: open the release valve by turning it counter-clockwise. Connect the air inlet fitting into the air supply hose lock fitting, then turn on the air valve letting the pump work for several times to eliminate any air in the system.

OPERATION

DANGER! This model is purpose designed to withstand greater loads than the hydraulic units can develop. For safety reasons, always ensure the workpiece and press tools are secured on the table and will not flex or suddenly “give way” causing danger to the operator or the component.

1. Place the arbor plate (17) on the press bed frame/table (18), then place the workpiece onto the arbor plate and align it beneath the ram as required.
   NOTE: care must be taken to ensure an arbor does not fall from the press work table. If necessary hold the configuration in position with clamps.

2. Close the release valve by turning it clockwise until it is firmly closed.

3. Connect the air inlet fitting to the workshop air supply hose lock fitting, turn on the air valve to let the pump work until the serrated saddle (5) nears the workpiece, then turn off the air valve. When air source is unavailable, pump the handle until the serrated saddle nears the workpiece.

4. Align workpiece and ram to ensure center-loading. Before applying any pressure to the workpiece, recheck the alignment with the ram and ensure that the workpiece and press tools are supported in such a way that they cannot flex.

   • WARNING! DO NOT apply off-centre loads.

5. Turn on the air valve or pump the handle to apply load onto the workpiece.

6. When work is done, turn off the air valve (or stop pumping the handle), and slowly and carefully remove the load from a workpiece by turning the release valve counter-clockwise in small increments.

7. Once ram has fully retracted, remove the workpiece from the press bed frame.

8. Disconnect the air inlet fitting from the air source.

NOTE: Always keep the piston retracted after use to avoid ram corrosion.

MAINTENANCE

NOTE: Maintenance and repair must only be carried out by a qualified personnel. Contact your Sealey stockist for details.

1. When the press is not in use, the hydraulic unit ram must be fully retracted to minimise corrosion. Remove the handle to inactivate the press.
2. Lubricate all moving parts at regular intervals.
3. Always keep the press clean, dry, and protected from harsh conditions.
4. Should you need to replace the oil, ensure the hydraulic unit ram is fully retracted. An excess of oil will render the press inoperative.
5. Use only appropriate Sealey hydraulic jack oil (Sealey Part Number: HJO500MLS/HJO5LS). DO NOT use brake fluid.
6. Purge the system to remove any air (see 5.4).
7. If press efficiency begins to drop, purge the system to eliminate any air from the hydraulic system (see 5.4).
8. Check your model parts information for spares.
