Handling Precautions
Avoid touching the working surface of the gauge with bare hands to prevent rust formation
Regularly inspect for damage, rust, or deformation
If rust appears, soak in gasoline, carefully wipe clean, and apply anti-rust oil
Never store working surfaces of two gauges together to prevent adhesion
After use, thoroughly clean and store in dry conditions
