b. Preparation. Before removal of any electrical, hydraulic, or air system components, ensure system component
is not energized or pressurized. Disconnect battery ground cables. Relieve air system pressure. Before removal of
fasteners (nuts, locknuts) remove any paint on threads to prevent binding of fastener.
