The symptoms you are describing are usually related to a pump flow problem. Anytime you have to operate a separate function to increase flow to another function towards a pump control problem or problem with the pump itself. Check inside your hydraulic filter and your suction screen for any signs of fine metal or debris that would confirm an internal mechanical component failure occurring. It will look like glitter in the oil and filter if present. If this is clean, have your pump flows and pressures tested and confirmed whether or not they are within factory specifications. If your pumps check out okay, you could have problems within your control valve or relief valve cartridges. Check inside you control valve and relief valve cartridges for any debris or damaged O-rings cause them to malfunction or stick. It's a pleasure to help anyway I can.
