Changing Hydraulic Oil/Fluid in a 2007 Bobcat T300 questions.

Is there a drain plug or does the Hyd. Fluid have to be pumped out?

How many Gallons does it hold?

Starting to have some Hydraulic Low Charge/Pressure issues so we figure start with oil then, check pressure, sensors, and so on before sending it to the dealer.

Thanks in advance!!
