4. Setup
Before beginning the strapping process, ensure you have the correct type and size of iron packing strap (16-19mm width, 0.5-1mm thickness) and appropriate seals.
- Prepare the Strap: Cut the iron packing strap to the required length, ensuring enough overlap for tensioning and sealing.
- Position the Strap: Wrap the strap around the item to be packaged. Ensure the strap is flat and not twisted. Overlap the two ends of the strap.
- Load into Tensioner: Insert the two overlapping ends of the strap into the tensioning tool. One end typically goes under the gripping mechanism, and the other through the winding mechanism. Refer to the tensioner's specific design for correct strap path.
5. Operating Instructions
Follow these steps to effectively strap your packages using the GeRRiT manual strapping tool and sealer.
- Step 1: Tension the Strap:
With the strap loaded into the tensioner, operate the tensioner's handle in a pumping motion. This will pull the strap tight around the package. Continue until the desired tension is achieved. The ergonomic and ratchet design of the handle assists in this process, minimizing effort.
- Step 2: Apply the Seal:
Once the strap is tensioned, place a metal seal over the overlapping straps, directly under the tensioner's cutting mechanism. Position the sealer tool over the metal seal and firmly press the handles together to crimp the seal. This creates a secure joint.
- Step 3: Cut the Strap:
After the seal is crimped, use the integrated cutting mechanism on the tensioner (or a separate cutter if not integrated) to cut the excess strap. Ensure the cut is clean and close to the seal.
- Step 4: Remove the Tool:
Carefully release the tensioner from the strap. The package is now securely strapped.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your strapping tool.
- Cleaning: After each use, wipe down the tool with a clean, dry cloth to remove any dust, dirt, or strap residue.
- Lubrication: Periodically apply a light machine oil to moving parts, such as gears, pivots, and cutting blades, to ensure smooth operation and prevent rust. Do not over-lubricate.
- Inspection: Regularly inspect the tool for signs of wear, damage, or loose components. Pay close attention to the gripping teeth, cutting blade, and handle mechanisms.
- Storage: Store the tool in a dry environment to prevent corrosion. Keep it in its original packaging or a protective case when not in use.
7. Troubleshooting
This section addresses common issues you might encounter during operation.
- Problem: Strap does not tension properly.
- Solution:
- Ensure the strap is correctly threaded through the tensioner.
- Check if the gripping teeth are worn or dirty. Clean or replace if necessary.
- Verify that the strap material and thickness are within the tool's specifications (16-19mm width, 0.5-1mm thickness).
- Problem: Seal is weak or fails.
- Solution:
- Ensure you are using the correct size and type of metal seals for your strap.
- Apply sufficient pressure to the sealer handles to fully crimp the seal.
- Inspect the sealer jaws for wear or damage.
- Problem: Strap slips after tensioning.
- Solution:
- Ensure the strap is not oily or greasy, which can reduce friction.
- Check the condition of the tensioner's gripping mechanism.
