6. Operating Instructions
Once the air supply is connected and staples are loaded, you can begin operation.
- Connect Air Supply: Reconnect the air hose to the stapler.
- Position the Tool: Place the nose of the stapler firmly against the workpiece where you want to drive a staple. The tool features a safety switch that prevents firing unless the nose is depressed against a surface.
- Fire the Stapler: Squeeze the trigger to drive a staple. The tool operates in a single sequential firing mode, meaning you must release the trigger and re-depress the nose for each staple.
- Adjust Depth (if applicable): If your model includes a depth adjustment, refer to the tool's specific markings to set the desired staple depth.
- Swivel Exhaust: The swivel exhaust system directs air away from the user for comfort.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pneumatic stapler.
- Disconnect Air Supply: Always disconnect the air supply before performing any maintenance.
- Lubrication: Apply a few drops of pneumatic tool oil (not included) into the air inlet before each use or after prolonged storage. This lubricates internal components.
- Cleaning: Keep the tool clean and free of dust and debris. Use a clean, dry cloth. Do not use solvents that could damage plastic parts.
- Check for Wear: Periodically inspect the tool for worn or damaged parts. Replace any damaged components immediately.
- Air Filter: Ensure your air compressor has a functioning air filter to prevent moisture and debris from entering the tool.
