Tips

For best results, ensure the workpiece is clean and free of debris before clamping. The swivelling pressure plate adapts to uneven surfaces, but using protective pads can prevent marks on delicate materials. Regularly lubricate the spindle thread to maintain smooth operation and extend the clamp's lifespan.
