At the start of each shift, what should be placed into the air intake of a pneumatic tool?

Grease
Oil
Lubricant
Water

The correct answer is: Lubricant

At the start of each shift, it is essential to place a suitable lubricant into the air intake of a pneumatic tool to ensure smooth operation and longevity of the tool. Lubricants designed for pneumatic tools typically contain specific additives that help reduce friction, prevent wear, and protect internal components from corrosion. Using an appropriate lubricant helps maintain the tool's efficiency and can improve its performance by ensuring that moving parts operate seamlessly. Additionally, this practice can minimize operational issues caused by inadequate lubrication, such as sticking or increased wear on the components. While grease and oil are often used in various machinery applications, they may not have the same properties needed for pneumatic tools that rely on air pressure for operation. Water, on the other hand, can lead to rust and damage internal parts. Therefore, lubricant is the most fitting choice to maintain pneumatic tools effectively.
