The operator should be particularly attentive to the operating oil pressure when the equipment is under load. This is crucial because operating under load increases the demand on the machinery, which can lead to fluctuations in oil pressure. Maintaining adequate oil pressure is essential for proper lubrication of engine components, and insufficient pressure can result in inadequate lubrication, leading to increased friction, overheating, and potential damage to the equipment. Monitoring oil pressure during these conditions helps ensure the equipment operates efficiently and safely, preventing breakdowns or failures that can occur from oil pressure issues.

While it's also important to monitor oil pressure during other times, such as when starting the equipment or during routine maintenance, the risk of oil pressure problems is heightened when the machine is actively working under load. This scenario puts the most stress on the system, making it essential for the operator to pay close attention to the oil pressure readings at those times.
