2. Safety Instructions

Operating a hydraulic press brake involves significant risks. Strict adherence to safety protocols is mandatory to prevent injury to personnel and damage to equipment. Always follow local safety regulations and company policies.

• Read the Manual: Ensure all operators have read and understood this entire manual before operating the machine.
• Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety glasses, steel-toed boots, and hearing protection. Gloves should be worn when handling materials but removed when operating controls to prevent entanglement.
• Machine Guarding: Never operate the press brake with safety guards removed or bypassed. Regularly inspect guards for damage.
• Lockout/Tagout: Always follow Lockout/Tagout procedures before performing any maintenance, adjustments, or clearing jams.
• Work Area: Keep the work area clean, well-lit, and free from obstructions. Ensure adequate space around the machine for safe operation and material handling.
• Emergency Stop: Familiarize yourself with the location and operation of all emergency stop buttons. Test them regularly.
• Authorized Personnel: Only trained and authorized personnel should operate or maintain the press brake.
• Material Handling: Use proper lifting techniques and equipment when handling heavy or large materials.

3. Setup

Proper installation and setup are critical for the safe and accurate operation of the press brake. Consult the machine's foundation drawings for specific requirements.

1. Foundation: Ensure the machine is installed on a level, stable concrete foundation capable of supporting its weight and dynamic loads.
2. Leveling: Use precision levels to ensure the machine frame is perfectly level. Adjust leveling pads as necessary.
3. Power Connection: Connect the machine to the appropriate electrical supply as specified on the machine's nameplate. Ensure proper grounding.
4. Hydraulic Fluid: Fill the hydraulic reservoir with the recommended hydraulic fluid to the specified level. Refer to the machine's data plate for fluid type and capacity.
5. Tooling Installation: Install the upper punch and lower die securely according to the bending application. Ensure tooling is clean, free of damage, and correctly aligned.
6. Safety Device Checks: Verify that all safety devices, including light curtains, foot pedals, and emergency stops, are functioning correctly.
7. Initial Test Run: Perform a no-load test run to check for smooth operation, proper ram movement, and absence of unusual noises.

4. Operating Instructions

This section outlines the general procedures for operating the Cincinnati Cost Breaker Hydraulic Press Brake. Specific bending operations may require additional steps or programming.

4.1 Pre-Operation Checks

• Inspect the machine for any visible damage or loose components.
• Check hydraulic fluid level and ensure no leaks are present.
• Verify tooling is correctly installed and secured.
• Clear the work area of any debris or unnecessary items.
• Ensure all safety guards are in place and functional.

4.2 Basic Operation Sequence

1. Power On: Turn on the main power switch. The control panel should illuminate.
2. Select Mode: Choose the desired operating mode (e.g., Manual, Jog, Automatic) from the control panel.
3. Set Parameters: Input bending parameters such as bend angle, back gauge position, and ram speed into the control system.
4. Material Placement: Carefully position the material on the lower die, ensuring it is flush against the back gauge.
5. Initiate Bend: Activate the ram descent using the foot pedal or two-hand control. Maintain a safe distance from the bending area.
6. Ram Return: The ram will automatically return to the top dead center after completing the bend, or it can be manually returned depending on the mode.
7. Remove Part: Once the ram is fully retracted, safely remove the bent part.

4.3 Emergency Stop Procedure

In case of an emergency, immediately press any red emergency stop button. This will cut power to the machine's moving parts. To reset, twist or pull the button to release it, then follow the control panel's instructions to restart the machine.
