4. Configuració
Before riveting, select and install the correct nosepiece for your rivet size.
- Identify Rivet Size: Determine the diameter of the rivet you intend to use. The Beta 1741 U supports 2.4mm, 3.2mm, 4.0mm, and 4.8mm rivets.
- Select Nosepiece: Choose the nosepiece that matches your rivet diameter. The nosepieces are typically stored on the handle of the tool.
- Remove Current Nosepiece (if applicable): Unscrew the currently installed nosepiece from the plier head.
- Install Correct Nosepiece: Screw the selected nosepiece firmly into the plier head until it is hand-tight. Ensure it is securely seated.
5. Instruccions de funcionament
Follow these steps to effectively use the riveting plier:
- Preparació de la peça de treball: Drill a hole in the materials to be joined that matches the rivet diameter. Ensure the hole is clean and free of burrs.
- Inserir rivet: Place the rivet through the prepared holes in the workpiece.
- Load Rivet into Plier: Insert the rivet mandrel (the pin) into the nosepiece of the riveting plier until the rivet head rests against the nosepiece.
- Position Plier: Place the rivet head firmly against the workpiece surface.
- Adjust Force (if necessary): The Beta 1741 U features an adjustable force mechanism. Rotate the knurled ring near the nosepiece to increase (+) or decrease (-) the pulling force. Adjusting the force can help achieve a consistent set for different rivet materials and thicknesses.
- Operate Plier: Squeeze the handles of the plier together firmly and steadily. You may need to squeeze multiple times until the rivet mandrel snaps off.
- Release Handles: Once the mandrel snaps, release the handles. The spent mandrel will be collected in the tool's internal collector.
- Inspect Rivet: Verify that the rivet is securely set and flush with the workpiece surface.

6. Manteniment
Regular maintenance ensures the longevity and optimal performance of your riveting plier.
- Netejar regularment: After each use, wipe down the tool with a clean, dry cloth to remove dust, debris, and metal shavings.
- Empty Mandrel Collector: Periodically empty the spent rivet mandrels from the collector. This prevents jamming and ensures smooth operation.
- Lubricació: Apply a small amount of light machine oil to moving parts and pivot points occasionally to ensure smooth action.
- Inspect Nosepieces: Check nosepieces for wear or damage. Replace them if they are worn or if rivets are not seating properly.
- Emmagatzematge: Store the plier in a dry environment to prevent rust. Use the handle lock to keep the handles closed for compact and safe storage.
