5. Setup
Before operating the strapping tool, ensure proper setup of the air supply and tool components.
5.1 Air Compressor Connection
- Ensure your air compressor is capable of providing an air pressure between 0.49-0.63Mpa (71-91 PSI). An air compressor is not included with this tool.
- Connect the air hose from your compressor to the gas nozzle on both the Pneumatic Strapping Tensioner and the Pneumatic Alloy Locking Machine. Use the provided air connector if necessary.
- Verify that all connections are secure to prevent air leaks.
- Set the air compressor regulator to the recommended operating pressure. Insufficient air pressure will negatively affect the strapping performance.

6. Operating Instructions
Follow these steps for safe and effective operation of the pneumatic steel strapping tool.
- Prepare the Strap and Seal:
Place an open metal seal onto the steel strapping. Bend the steel strapping approximately 50mm (2 inches) away from the seal, creating a loop for the tensioner.
- Position the Strapping:
Wrap the steel strapping around the package or item to be secured. Ensure the strapping is correctly aligned and positioned.
- Tension the Strapping (Using Pneumatic Strapping Tensioner):
Insert the strapping into the tensioner. Turn the tension rotating knob (tighten speed control) clockwise. Continue turning until the strapping is tightened to the desired tension, ensuring it is secure around the package. The tensioner will automatically feed the strapping.
- Seal the Strapping (Using Pneumatic Alloy Locking Machine):
Position the Pneumatic Alloy Locking Machine over the metal seal and the overlapped strapping. Press the lock trigger handle of the sealer firmly to complete the locking process. This will crimp the seal, securing the strap ends together.
- Cut the Strapping (Using Pneumatic Strapping Tensioner):
After sealing, tilt the tensioner upwards vertically. This action will cut the excess strapping. Then, turn the rotary knob on the tensioner to its stop position to release the tool from the strap.
- Inspect the Strapping:
Verify that the strap is tightly secured and the seal is properly crimped. If necessary, repeat the process or adjust tension for optimal security.

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pneumatic strapping tool. Always disconnect the air supply before performing any maintenance.
- Daily Cleaning: Wipe down the tools with a clean, dry cloth to remove dust, dirt, and debris.
- Lubrication: Apply a few drops of pneumatic tool oil into the air inlet of both tools daily or before each use. This lubricates internal components and prevents corrosion.
- Inspect Air Connections: Regularly check air hoses and connections for wear, damage, or leaks. Replace any damaged components immediately.
- Check Moving Parts: Inspect the feed wheel, cutting blade, and sealing jaws for wear or damage. Replace worn parts as needed.
- Storage: Store the tools in a clean, dry environment when not in use.
8. Troubleshooting
This section addresses common issues you might encounter and provides solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Insufficient Tensioning | Low air pressure; Worn feed wheel; Incorrect strap thickness. | Check air compressor pressure (0.49-0.63Mpa); Replace feed wheel; Ensure strap thickness is within 0.6-1.2mm range. |
| Poor Sealing/Crimping | Low air pressure; Worn sealing jaws; Incorrect seal type/size. | Verify air pressure; Inspect and replace sealing jaws if worn; Use appropriate metal seals for steel strapping. |
| Strap Not Cutting Cleanly | Dull or damaged cutting blade. | Inspect and replace the cutting blade on the tensioner. |
| Air Leaks | Loose connections; Damaged O-rings or seals. | Tighten all air connections; Inspect and replace O-rings or seals as needed. |
| Tool Not Operating | No air supply; Air pressure too low; Internal blockage. | Check air compressor and hose connection; Adjust air pressure; Consult support if internal blockage is suspected. |
