4. Setup

4.1 Connecting to Air Supply

1. Ensure the air compressor is off and the air hose is disconnected from the compressor.
2. Connect the air hose to the tool's swivel plug.
3. Set the air compressor pressure between 70-120 PSI (4.8-8.3 bar). Do not exceed 120 PSI.
4. Connect the air hose to the compressor and turn on the compressor.
5. Check for air leaks. If leaks are present, disconnect the air supply and tighten connections.

4.2 Loading Fasteners

The TN51P1P uses 15 gauge angled finish nails, ranging from 1-1/4" to 2-1/2" in length.

1. Disconnect the air supply from the tool.
2. Pull back the pusher assembly until it locks into place.
3. Insert a strip of 15 gauge angled finish nails into the magazine, ensuring the nail points are facing down and the collation angle matches the tool's magazine.
4. Release the pusher assembly, allowing it to push the nails forward until they are seated correctly.
5. Reconnect the air supply.

4.3 Adjusting Depth of Drive

The tool features a tool-free depth adjustment mechanism.

1. Disconnect the air supply from the tool.
2. Locate the depth adjustment dial or lever near the nose of the tool.
3. Rotate the dial or move the lever to increase or decrease the depth of the nail drive. Test on a scrap piece of material to achieve the desired depth.
4. Reconnect the air supply.

4.4 Selecting Firing Mode

The selectable trigger allows you to choose between two firing modes:

• Sequential Actuation: The trigger must be pressed for each fastener. The contact element must be depressed against the workpiece before the trigger is pulled. This mode offers precise fastener placement.
• Contact Actuation (Bump Fire): The tool will fire a fastener each time the contact element is depressed against the workpiece while the trigger is held down. This mode is suitable for rapid fastening.

To switch modes, locate the selector switch on the trigger assembly and move it to the desired position.

5. Operating Instructions

1. Ensure all safety precautions are followed and the tool is properly set up.
2. Hold the tool firmly with both hands.
3. Place the nose of the tool firmly against the workpiece where the fastener is to be driven.
4. For sequential mode, depress the contact element against the workpiece, then pull the trigger. For contact mode, hold the trigger and depress the contact element against the workpiece.
5. After driving a fastener, lift the tool from the workpiece.

5.1 Dry Fire Lockout

The dry fire lockout feature prevents the tool from operating when the magazine is empty. This protects the tool from unnecessary wear. When the tool stops firing, it indicates that the magazine needs to be reloaded with fasteners.

5.2 Clearing Jams

If a fastener jam occurs:

1. Immediately disconnect the air supply from the tool.
2. Locate the quick clear latch near the nose of the tool.
3. Open the latch to expose the fastener channel.
4. Carefully remove the jammed fastener using pliers if necessary. Do not force it.
5. Close the quick clear latch securely.
6. Reconnect the air supply and test the tool on a scrap piece.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your Senco TN51P1P nailer.

• Oil-Less Design: This tool features an oil-less design, meaning routine lubrication of the internal components is not required. Do not add oil to the air inlet.
• Daily Cleaning: Keep the tool clean and free of debris. Wipe down the exterior with a clean, dry cloth.
• Inspect Air Filter: Periodically check the air inlet filter for clogs and clean if necessary.
• Check Fastener Channel: Ensure the fastener channel is clear of any residue or small debris that could cause jams.
• Store Properly: When not in use, store the tool in a dry, secure location, disconnected from the air supply.

7. Troubleshooting

If you encounter issues with your Senco TN51P1P nailer, refer to the following common troubleshooting steps:

• Tool Not Firing:

  • Ensure magazine is loaded with fasteners (dry fire lockout engaged if empty).
  • Verify the contact element is fully depressed against the workpiece.
  • Check for jammed fasteners.
• Nails Not Driving Fully:
  • Increase air pressure within the recommended range.
  • Adjust the depth of drive setting.
  • Ensure the correct length and gauge of fasteners are being used.
• Nails Jamming Frequently:
