Power tongs are essential for makeup and breakout operations of drill pipes, casing, and tubing in oilfield drilling. To maintain peak performance, a preventative maintenance schedule is required, focusing on lubrication of moving parts every 24 hours of operation and regular inspection of hydraulic seals and jaw dies. Using high-quality hydraulic oil and maintaining system pressure within the manufacturer's specified range (typically 2000-3000 PSI) will extend the equipment's lifespan and ensure consistent torque delivery.
