Setup
Follow these steps to set up your A03 Manual Paste Liquid Filling Machine:

- Base Placement: Place the main machine body on a stable, flat, and level surface. Ensure there is enough space around the machine for operation and maintenance.
- Hopper Assembly: Attach the stainless steel hopper to the top of the main machine body. Ensure it is securely fastened to prevent leaks during filling.
- Nozzle Installation: Select the appropriate nozzle (4mm or 8mm) for your filling material and attach it to the filling outlet. Ensure it is tightened to prevent dripping.
- Initial Cleaning: Before first use, thoroughly clean all parts that will come into contact with the filling material using a suitable cleaning agent, especially the hopper and nozzles. Rinse thoroughly with clean water and dry.

Operating Instructions
Follow these steps for operating the A03 Manual Paste Liquid Filling Machine:
- Adjusting Filling Volume: Locate the filling volume regulator knob (often a screw or lever mechanism). Turn the knob to adjust the desired filling volume between 0-50ml. A test fill is recommended to calibrate the exact volume.
- Loading Material: Pour the liquid or paste material into the hopper. Ensure the material is free of large particles that could clog the nozzle.
- Positioning Container: Place the container (bottle, jar, etc.) to be filled directly under the filling nozzle.
- Initiating Fill: Pull down the manual operating lever firmly and smoothly. This action draws material from the hopper into the cylinder and then dispenses it through the nozzle into your container.
- Completing Fill: Release the lever. The machine will reset for the next fill cycle.
- Repeat: Repeat steps 3-5 for subsequent containers.

Important Safety Note:
- Always wear appropriate personal protective equipment (PPE) such as gloves and eye protection, especially when handling chemicals or hot liquids.
- Do not overfill the hopper.
- Ensure the machine is stable and cannot tip over during operation.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your A03 Filling Machine:
- Daily Cleaning: After each use, especially when changing materials, thoroughly clean the hopper, cylinder, and nozzles. Disassemble parts as needed for complete cleaning. Use warm soapy water for general cleaning, and appropriate solvents for specific materials if necessary. Rinse thoroughly and dry.
- Lubrication: Periodically apply food-grade lubricant to moving parts, such as the piston and lever mechanism, to ensure smooth operation.
- Seal Inspection: Regularly inspect the seal ring for wear and tear. Replace it if cracks or damage are visible to prevent leaks. A spare seal ring is included in the package.
- Storage: When not in use, store the machine in a clean, dry environment, away from direct sunlight and extreme temperatures.
