Question 46Motor Plants - 1st Asst/Chief70% to pass
Before any auxiliary diesel engine hydraulic starting system is opened for servicing or repair, you must _______________.
AI Explanation
The correct answer is A) bleed off all hydraulic pressure from the system.
Before servicing or repairing an auxiliary diesel engine hydraulic starting system, it is crucial to bleed off all hydraulic pressure from the system. This is a safety precaution to prevent accidental release of pressurized hydraulic fluid, which could cause injury. Releasing the pressure ensures that the system is depressurized and can be safely worked on.
The other options are incorrect because they do not address the primary safety concern of depressurizing the hydraulic system. Placing control levers in the 'HOLD' position (B) or blocking hydraulic hoses (C) do not necessarily eliminate the pressure in the system. Ensuring the fluid reservoir is full (D) is important but does not directly address the need to depressurize the system before servicing.
