Accumulator pre-charge pressure

Having the pressure of the nitrogen gas pre-charged to the correct level is critical to proper operation. This is determined by the amount of hydraulic pressure set at the pump to control the hydraulic cylinders. The pre-charge level of the accumulator should be set to 65% of this.
