5.0 Features and Terminology

Model HP-35A shown as representative; other models may vary

Figure 1

6.0 Assembly

Refer to Figure 1 for identification.

1. Use a lifting device, such as a hoist or forklift with straps, to position machine upright.

2. Bolt the fram e brackets to the main frame with the provided screws and hex nuts. Finger tighten only.

3. The press should be placed within a well-lit area, upon a level floor, preferably concrete. Lower the press onto the floor, allowing it to stabilize on the brackets. Fully tighten t he hex nuts on the frame brackets.

4. The hex filler plug (see part s breakdown: item #17 for HP-5A; #8A for HP-15A; #8D for HP35A) was installed for shipping purposes. Remove this and replace it with the provided vented plug.

5. Place the end of the pump handle into the handle socket, and secure it with the screw.

7.0 Operation

Refer to Figure 1 for identification.

1. Remove all items from bed plates.

6. If desired, slide ram assembly laterally (15and 35-ton models only) by mounting the hand crank onto the lateral shaft and rotating it. Do not attempt to slide ram during operation.

7. The handwheel can be used to rapidly adjust the ram extension screw into or out of the plunger.

Note: The length of ram screw extending out of the piston should be kept as short as possible. Raise the table rather than extend the screw to its travel limit.

8. Close valve by rotating release valve handle clockwise as far as it will turn.

9. Pump the handle to lower the ram until it makes light contact with workpiece. Align the workpiece to ensure that desired contact point is directly beneath the press head. Slowly pump handle again until load begins to be applied to workpiece.

10. Remove your hand from workpiece area and step toward the side of the press (do not sta nd directly in front of workpiece). Continue slowly pumping to complete the operation.

11. When operation is complete, slowly retract ram by incrementally turning release valve handle counter-clockwise.

2. Remove table holding pins. (Support the table frame on the HP-5A.)

3. Raise or lower table fram e to desired position, so that when workpiece is m ounted, it will be close to the ram press head.

Model HP-5A: Raise or lower table frame by hand.

Models HP-15A,-35A: Rotate crank handle to raise or lower table frame.

4. Re-insert table holding pins. Pins must be fully engaged through front and back holes of the frame.

5. Place workpiece onto bed plates.

Make sure workpiece is

center-loaded and secure before pressing, a nd that table holding pins are properly inserted. Some objects may have a tendency to pop out or explode under pressure. Exercise proper precautions.

8.0 Maintenance

• Keep the press clean, and periodically lubricate joints and moving parts with light oil.

• Inspect the press before each use, for signs of damage, bent pins, missing or loose bolts, cracked welds, oil leaks, abnormal operation, and the like. Make repairs o r replacements as needed before putting the machine back into service.

• Periodically remove filler plug (#17/HP-5A; #8A/HP-15A; #8D/HP-35A) to check that hydraulic cylinder is filled with oil. Top off as needed with good quality hydraulic oil. Reins ert filler plug.

• Flush and replace the oil in the hydraulic cylinder approximately every 2 years. Ref er to section 4.0 Specifications for oil capacity for your particular model.
