What safety precaution must be taken when removing a wheel from an axle?

• A. Ensure the wheel is securely fastened
• B. Verify that the tire is completely deflated before removing a wheel from an axle or before wheel disassembly
• C. Use special tools for wheel removal
• D. Check for corrosion on the axle

Answer: (B)

When removing a wheel from an axle, it is crucial to verify that the tire is completely deflated before proceeding with the disassembly. This is essential because an improperly deflated tire can lead to an unexpected release of pressure, which poses risks of injury due to sudden bursts or flying debris. A fully deflated tire will prevent this hazardous situation, allowing the mechanic to handle the wheel safely and without the risk of a tire explosion. Other safety precautions, such as ensuring the wheel is securely fastened or checking for corrosion on the axle, are important maintenance steps but do not address the immediate risks associated with tire pressure during wheel removal. Using the appropriate tools is also a standard practice to ensure efficient and safe operations, but it does not mitigate the potential danger posed by a pressurized tire. Hence, verifying the tire’s complete deflation is the key safety precaution to minimize risk and ensure safe handling.
