3. Setup

3.1 Connecting to Air Compressor

The VEVOR MCN55 requires an air compressor with a capacity of 15+ gallons and an operating pressure range of 70-120 PSI. Ensure your compressor meets these requirements.

1. Attach the air hose to the air hose connector on the nailer.
2. Set the air compressor pressure regulator to the recommended operating pressure (70-120 PSI). Start with a lower pressure and adjust as needed for proper nail depth.
3. Check all connections for leaks before operation.

3.2 Loading Nails

The MCN55 uses wire-collated coil nails. Ensure you are using the correct nail type and size (1 to 2-1/4 inches in length).

1. Disconnect the air supply from the nailer.
2. Open the side-loading magazine cover.
3. Place the coil of nails into the magazine, ensuring the nails are properly aligned with the feed mechanism.
4. Adjust the nail length setting inside the magazine if applicable, to match the length of your nails.
5. Close the magazine cover securely.

3.3 Nail Length Adjustment (Video Demonstration)

This video demonstrates the process of adjusting the nail length setting within the magazine, which is crucial for proper nail feeding and operation. While the video features a CN70 model, the adjustment mechanism is similar for the MCN55.

4. Operating Instructions

4.1 Firing Modes

The MCN55 Coil Siding Nailer operates in a bumper firing mode, allowing for rapid, sequential nailing.

• Bumper Firing: Hold the trigger and press the contact trip against the workpiece to drive a nail. This allows for quick, repetitive nailing.
• Single Sequential Firing: For precise placement, press the contact trip against the workpiece, then pull the trigger to drive a nail. Release the trigger and lift the tool from the workpiece to reset for the next nail.

4.2 Driving Nails

1. Ensure the air supply is connected and the pressure is set correctly.
2. Position the nailer firmly against the workpiece at the desired location.
3. Depending on the selected firing mode, either press the contact trip and pull the trigger (single sequential) or hold the trigger and bump the contact trip against the surface (bumper firing).
4. Observe the nail depth. Adjust air pressure or the depth adjustment mechanism (if available on your model) to achieve the desired flush or countersunk finish.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your VEVOR MCN55 Coil Siding Nailer.

• Lubrication: Apply a few drops of pneumatic tool oil into the air inlet before each use or after every few hours of continuous operation. This lubricates internal components and prevents wear.
• Cleaning: Keep the tool clean and free of debris. Regularly clean the magazine and nosepiece to prevent jams.
• Inspection: Periodically inspect the tool for worn or damaged parts. Replace any worn components immediately. Check for loose fasteners and tighten them as necessary.
• Air Filter: Ensure your air compressor has a functioning air filter to prevent moisture and contaminants from entering the nailer.
• Storage: When not in use, disconnect the air supply and store the tool in a clean, dry place away from direct sunlight and extreme temperatures.
