Block 9 is dedicated to detailing critical information related to the lubrication system of a piece of equipment, including its operational status, any irregularities, and maintenance actions taken. This is crucial for ensuring that machinery components are adequately lubricated, which directly impacts their performance and lifespan.

Understanding the function of the lubrication system is vital for maintaining equipment reliability and efficiency. This block plays a key role in monitoring lubricants, noting temperature ranges, and observing any contamination, all of which contribute to the overall health of the equipment.
