Usage Features
The Arcan CP401 is designed for versatile use with several features that enhance its functionality and user experience:
- Adjustable Press Bed: The press bed can be moved up and down to accommodate different workpiece sizes and to optimize the ram's working range. This adjustability ensures that the workpiece can be positioned effectively for the 6.75-inch stroke.
- Air-Over-Hydraulic System: This dual-action system allows for quick initial ram movement using air pressure, followed by precise, high-force application via the hydraulic pump handle. This combination offers both speed and control during operation.
- Pressure Gauge: The press is equipped with a pressure gauge, allowing users to accurately measure the pressing force being applied. This is crucial for preventing over-pressing and ensuring consistent results.
- Press Plates: The inclusion of two press plates (1" x 3" x 14") provides stable support for various workpieces, distributing the load evenly and protecting the press bed.
- Pushing Adapter and Bearing Shield: These accessories (though not needed for assembly) are designed to enhance specific applications. The pushing adapter helps in applying force to smaller or irregularly shaped items, while the bearing shield is essential for safely pressing bearings on or off, protecting both the user and the workpiece.
- Safety Features: The manual emphasizes several safety instructions, including the importance of wearing safety goggles and protective clothing, ensuring proper load centering, and fully engaging bed pins. The breather valve on the pump must be open before operation to prevent damage from hydraulic fluid pressure.
Maintenance Features
The manual outlines several maintenance and inspection points to ensure the longevity and safe operation of the press:
- Pre-Use Inspection: Users are instructed to visually inspect the press before each use for signs of cracked welds, bent bed pins, loose or missing bolts, leaks, or any other structural damage. Any damaged or abnormally operating press must be removed from service immediately.
- Annual Inspection: An annual inspection by a manufacturer's authorized repair facility is recommended to ensure all components are in good working order and to replace any defective parts or warning labels.
- Hydraulic Fluid Levels: Maintaining proper hydraulic fluid levels is crucial for the pump's performance and longevity.
- Bolt Tightness: Regular checks for bolt tightness are advised, especially for the press feet and Z-bars, to ensure stability and prevent rocking.
- Breeding Air Procedure: A detailed procedure for bleeding air from the hydraulic system is provided, which is essential for maintaining optimal pump performance and preventing issues caused by air in the lines. This involves turning the valve handle, opening the petcock valve, and using an air hose to flow air into the pump while the air motor is operating.
- Replacement Parts List: A comprehensive replacement parts list is included, detailing all components of the press, pump, and ram, along with their part numbers and quantities. This facilitates easy ordering of replacement parts, ensuring that the press can be maintained and repaired with genuine components. Items marked with a star (*) are only available as part of a seal kit (RSCBP1217).
Overall, the Arcan CP401 is a robust and versatile shop press designed for demanding applications, with a strong emphasis on user safety and ease of maintenance.
