3. Operating Instructions
The Arrow Fastener AOP0557A stapler offers dual-mode stapling for both fixed and temporary applications.
Fixed Stapling
For permanent fastening, ensure the anvil (the metal plate at the bottom of the stapler) is set to the fixed position. In this mode, the staple legs will bend inward, securely binding the papers together. Simply insert the papers between the stapler jaws and press the handles together firmly.
Temporary Stapling
To enable temporary stapling, rotate the anvil 180 degrees. In this position, the staple legs will bend outward, allowing for easy removal of the staple without tearing the paper. This mode is ideal for temporary document organization or craft projects where staples may need to be removed later.

5. Troubleshooting
If you encounter any issues with your Arrow Fastener AOP0557A Metal Plier Stapler, consider the following common troubleshooting steps:
- Staples not feeding: Ensure the staple rail is fully loaded with compatible staples and is securely closed. Check for any bent staples in the rail.
