1.3 Safety Precautions

• All personnel must read and understand this manual thoroughly before installation, operation, or maintenance.
• Isolate the power supply and relieve all system pressure before any disassembly or maintenance to prevent injury or equipment damage.
• Do not operate the pump beyond the rated maximum pressure, speed, or temperature limits to avoid failure, leaks, or hazards.
• Use only recommended hydraulic fluids and maintain fluid cleanliness to prevent premature wear and component blockage.
• Wear appropriate personal protective equipment (PPE) such as safety glasses and gloves when working on the system.

3. Installation Instructions

3.1 Mounting

• The pump can be flange-mounted (standard) or foot-mounted (F-option). The mounting surface must be rigid and flat to prevent housing distortion.
• Align the pump shaft with the drive shaft using a flexible coupling. Maximum misalignment: 0.1 mm radial, 0.05 mm axial, 1° angular.
• Tighten mounting bolts to the recommended torque: M8 (18-22 N·m), M10 (35-40 N·m), M12 (60-65 N·m).

3.2 Plumbing

• Inlet Line: Use a short, large-diameter, smooth-bore hose. Avoid elbows and restrictions. Ensure no air leaks.
• Outlet Line: Install a high-pressure hose or pipe with a pressure relief valve.
• Drain Line: Direct the case drain line back to the tank separately. Do not route it through a filter or valve.

3.3 Priming & Filling

• Fill the pump and inlet line with clean hydraulic fluid before startup.
• Rotate the shaft manually by hand to bleed air from the cartridge.
• Maintain proper oil level in the reservoir to prevent air ingestion.

4. Operation Guidelines

4.1 Startup

• Start the pump at low speed (≈600 rpm) with the system unloaded for 5-10 minutes to circulate fluid and purge air.
• Check for leaks, unusual noise, or vibration.
• Gradually increase speed and load to operating conditions.

4.2 Normal Operation

• Operate within the specified pressure and speed ranges.
• Monitor fluid temperature (max 82°C) and condition.
• Avoid prolonged operation at maximum pressure and low speed.

4.3 Shutdown

• Reduce speed and unload the system before stopping.
• For extended shutdowns, protect the pump from contamination and corrosion.

5. Maintenance & Troubleshooting

5.1 Maintenance Schedule

• Daily: Check fluid level and for leaks.
• Weekly: Inspect fluid condition; check for abnormal noise/vibration.
• Every 250 hrs: Change or clean inlet filter.
• Every 1000 hrs: Change hydraulic fluid and all filters.
• Every 2000 hrs: Inspect shaft seal and bearings.

5.2 Common Troubleshooting

5.3 Cartridge Replacement

1. Relieve pressure and disconnect hoses.
2. Remove the end cover bolts.
3. Extract the old cartridge.
4. Insert new cartridge, aligning keyways.
5. Reassemble and prime.

6. Storage & Handling

• Store in a clean, dry environment.
• Fill with preservative oil and seal ports if stored for over 3 months.
• Protect shafts and threads from damage.
