What tools should not be used with R410A if they were previously used with R22?

Do not use the following tools if they have been used with conventional refrigerant (R22): gauge manifold, charging hose, refrigerant leak detector, check valve, refrigerant charge spout, vacuum gauge, and refrigerant recovery equipment. R410A does not contain chloride, so leak detectors for older refrigerants will not detect an R410A leak. (Page 7)
