Hi my name is***** will be glad to try to help you out. I don't believe pilot pressure is adjustable on this machine but your main pressures are adjustable. Usually when you have low pilot pressure is the result of a potential pump problem or problem with the control valve. If any further help is needed, please grab me the machine serial number and I will see what I have for specifications for any further help if needed when I get back to the shop. It's a pleasure to help anyway I can.
