a. Handling of Disassembled Parts.
A parts tray or suitable re-

This is especially important where
is assembled by a technician other than the one who disassembled it.

assemblies are to be removed by rubbing down with crocus cloth. Be
sure to remove filings from threads by brushing with a camel's hair
