Loading Instructions:
- Always refer to your specific staple gun's instruction manual for precise loading procedures.

4. Storage and Care
Proper storage of your Arrow T50 staples ensures their longevity and optimal performance.
- Keep Dry: Store staples in a cool, dry place to prevent rust and corrosion. Moisture can compromise the integrity of the staples and lead to misfires or damage to your stapler.
- Original Packaging: Keep staples in their original packaging until ready for use to protect them from dust and environmental elements.
- Avoid Bending: Do not store staples where they might be bent or damaged, as this can cause feeding issues in your staple gun.

- Inspect the staple strip for any bends or damage. Replace damaged strips.
- Clean the staple gun's magazine and firing mechanism according to its manual.
- Staples Bending/Not Penetrating:
- Verify that the material you are stapling into is not too hard for the staple length.
- Ensure you are applying sufficient and even pressure to the staple gun.
- Check if the staple gun's spring mechanism is functioning correctly (refer to stapler manual).
- Ensure staples are not rusted or corroded.
- Staple Gun Jamming:
- Remove any jammed staples carefully, following your staple gun's safety instructions.
- Use only genuine Arrow T50 staples or other high-quality, compatible staples to minimize jams.
- Avoid mixing different types or sizes of staples in the magazine.
