5. Operating Instructions
This section details the steps for operating your LOYALHEARTDY filling machine.
5.1. Adjusting Filling Volume
The machine features a filling ruler design for precise volume adjustment.
- Locate the filling ruler and adjustment mechanism on the side of the pneumatic cylinder.
- Turn the adjustment knob to set the desired filling volume between 50ml and 500ml. The ruler provides a visual guide for the piston's travel distance, which corresponds to the filling volume.
- Perform a test fill to verify the accuracy of the set volume and make fine adjustments as needed.

5.2. Filling Process
- Ensure the hopper is clean and securely attached.
- Pour the liquid or paste product into the hopper.
- Turn on the main power switch.
- Place the container to be filled under the nozzle.
- Press the foot pedal to initiate a filling cycle. The machine will draw product from the hopper and dispense the pre-set volume into the container.
- Release the foot pedal. The anti-drip nozzle will prevent further dripping.
- Repeat the process for subsequent containers.
