Ned > 2Explanation / Answer
Answer: Turn off presses 2, 4 and 5, then shut valves D and F.
Explanation:
Servicing press 2 and 5 can be done after turning them off. Since their lubricating systems have to be diassembled, the supply of lubricating oil to both of them must be cut.
To stop the supply of oil to press 2, valve D must be shut.
Oil supply to press 5 can be stopped by closing the valve F. However, if valve F is shut, the supply of oil to press 4 will be stopped as well. So, with valve F shut, press 4 cannot be operated and therefore must be turned off (before valve F is shut).
