Setup and Assembly
Before operating the machine, ensure proper setup and connection to an air supply.
- Unpacking: Carefully remove the strapping machine from its packaging. Inspect for any signs of damage during transit.
- Air Supply Connection: Connect the air supply pipe to the air connector on the machine. Ensure the connection is secure and leak-free. The required working pressure is 0.5-0.7Mpa (72-100psi), with an ideal pressure of 0.63Mpa. The air pump joint is constructed from high-quality alloy material.
- Strap Loading: Prepare the PET or PP strapping material. Ensure the strap width is between 13mm and 19mm and thickness is between 0.5mm and 1.5mm.
- Initial Inspection: Verify that all moving parts are free and clear, and that the cutting device and tensioner are functioning correctly.

Operating Instructions
Follow these steps for effective strapping using the pneumatic baler.
- How to Bind:
Bundle the article with the packaging belt. Hold the lapped part with your left hand, leaving approximately 300mm of tail. Pull the remaining part out with your right hand.

Figure 4: Step-by-step illustration of preparing the strap around the package.
- Place Packaging Belt:
Hold the handle and tightener with your right hand to ensure the maximum opening dimension between the take-up pulley and the tightening toothed plate. Insert both the upper and lower parts of the packaging belt into the packaging machine. Note: The lapped part of the packaging belt must be separated by the blade of the blade holder. Release the tightener (the take-up pulley clips the packaging belt tightly).
- Tighten the Packaging Belt:
Press the tightening button (located on the right side) with the thumb of your right hand until the packaging belt is fully tight.
- Vibration and Cutting (Fusion):
Press the fusion button (red button) with the thumb of your right hand until the packaging belt is fused and cut off. Note: Continue pressing the fusion button until the vibration timer stops automatically (fusion time: 2-5 seconds).

- Take Down the Packaging Machine:
Press the handle and tightener tightly with your right hand. Press the rewinding button with the little finger of your right hand until the belt is released from the take-up pulley. Press the handle and tightener tightly, then remove the tool from the packaging belt. Note: Do not remove the packaging machine until the packaging belt is released.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your strapping machine.
- Cleaning: Regularly clean the machine, especially the strapping path, tensioning wheels, and cutting blades, to prevent build-up of dust and strap residue. Use a dry cloth or compressed air.
- Lubrication: Apply a few drops of pneumatic tool oil to the air inlet daily or before each use to lubricate internal components and prevent corrosion.
- Blade Inspection: Periodically inspect the cutting blades for wear or damage. Replace worn blades to ensure clean and efficient cuts. The heavy cutting device is designed for 0.5-1.5mm thick belts, while the friction cutting device is for 0.5-0.7mm thick PET belts.
- Air Filter: Check and clean the air filter regularly to ensure a clean air supply to the machine.
- Storage: When not in use, store the machine in a clean, dry place, disconnected from the air supply.
Troubleshooting
This section provides solutions to common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine not tensioning strap properly | Low air pressure; Worn tensioning wheels; Incorrect strap thickness. | Check air supply and pressure (0.5-0.7Mpa); Inspect and clean/replace tensioning wheels; Ensure strap thickness is within 0.5-1.5mm. |
| Strap not fusing or welding poorly | Incorrect fusion time setting; Contaminated welding surface; Worn friction plate. | Adjust fusion time (2-5s); Clean welding surfaces; Inspect and replace friction plate if worn. |
| Strap not cutting cleanly | Dull or damaged cutting blade; Strap material too thick for friction cut. | Inspect and replace cutting blade; Ensure strap thickness is appropriate for the cutting device used (heavy for 0.5-1.5mm, friction for 0.5-0.7mm). |
| Air leakage | Loose air connection; Damaged O-rings or seals. | Tighten air connections; Inspect and replace O-rings or seals as needed. |
