Before servicing a pneumatic tool, what is the first action that must be taken?

• A. Check the tool for wear
• B. Disconnect the air supply
• C. Wear safety goggles
• D. Read the operating manual

Answer: (B)

Before servicing a pneumatic tool, the first action that must be taken is to disconnect the air supply. This is crucial for ensuring safety during maintenance or repair work. When the air supply is disconnected, it prevents the tool from accidentally engaging or operating while a person is working on it. Not taking this step can lead to serious injuries, as pneumatic tools can be powerful and operate unexpectedly if there is still air pressure within the system. The other actions, while important in their own right, should follow the disconnection of the air supply. Checking the tool for wear, for example, is an important maintenance step, but it should only be done once the risk of accidental operation is removed. Wearing safety goggles is always a recommended safety practice, but it does not address the immediate risk associated with the tool being powered. Reading the operating manual is critical for understanding the tool’s features and safe operation but should not be the first step before servicing. Therefore, disconnecting the air supply is the essential first action to prioritize safety.
