T180 A/C R134A capacity?

[Max Power]

Can anyoe tell me what the recommended amount of R134A is for a 2006 T180? This thing has 240 hours on it and there is a leak already. I'm going to add die but I need to know how much R134A to add. I saw somewhere that a S185 uses 2.2Lbs. Is the T180 the same?

My T180 manual, p 80-100-6 says the A/C system holds 2.0 lbs of R134A refrigerant. ---RC
