Setup and Installation
- Unpacking: Carefully unpack all components. Inspect for any shipping damage. Report any damage immediately to the carrier and supplier.
- Placement: Position the press on a flat, level, and sturdy surface capable of supporting its weight (766 lbs). Ensure adequate clearance around the machine for safe operation and maintenance.
- Anchoring: Securely anchor the press to the floor using appropriate fasteners to prevent movement during operation.
- Electrical Connection: Connect the 110 Volt single-phase motor to a dedicated 32 Amp circuit. Ensure all electrical connections comply with local codes and regulations.
- Hydraulic Fluid Check: Verify the hydraulic oil level in the 5L reservoir. Top up with recommended hydraulic fluid if necessary.
- Foot Pedal Connection: Connect the foot pedal control unit to the main press unit.

Operating Instructions
- Pre-Operation Check: Before each use, inspect the press for any visible damage, leaks, or loose connections. Ensure all safety guards are in place.
- Power On: Turn on the main power switch. The motor should start.
- Adjust Pressure/Speed: Use the control knob on the motorized pump unit to set the desired pressure and speed for the pressing operation. Refer to the pressure gauge (Figure 5) for accurate readings.
- Position Workpiece: Place the workpiece securely on the press bed. Ensure it is stable and properly aligned.
- Initiate Pressing: Depress the foot pedal to lower the ram. The ram will descend at 8.8 mm/s.
- Release Pressing: Release the foot pedal to retract the ram. The ram will return at 12.5 mm/s.
- Emergency Stop: In case of an emergency, press the red emergency stop button located on the control panel or foot pedal.
- Power Off: After use, turn off the main power switch.
