Final answer:
The specific air pressure required in the air tank while loading MHU-204/M and MHU-196/M lift trailers is not noted in the question or resources, but will be in the equipment's technical specifications or manual. For reference, a car tire maintains a pressure of 2.20 x 105 Pa (around 32 psi) to work correctly under heavy loads.
Step-by-step explanation:
The specific air pressure to be maintained in the air tank before loading with the MHU-204/M and MHU-196/M lift trailers isn't provided in the question, nor found in the provided references. Usually, specific air pressure requirements for such equipment will be found in their technical specifications or operation manuals. However, based on general principles, it's important that the air pressure is kept within safe and operative levels that match the design of the equipment being used.
For example, consider a car tire, which typically contains air at a pressure of about 2.20 x 105 Pa (approximately 32 psi). This pressure is significantly greater than normal atmospheric pressure (which is virtually referred to as 'zero gauge pressure'). The reason for such a pressure being maintained is to allow the tire to maintain its shape and function properly, even under the heavy load of the vehicle. Similar principles would apply to maintaining air pressure in the air tank when loading MHU-204/M and MHU-196/M lift trailers.
