Counterbalance - Pressure Chart

RD0019

Introduction

This chart shows the correct pressures for the counterbalance tank. Measure the pressure at the top of Z-Axis travel for VMCs and at the top of Y-Axis travel for HMCs. Pressure that is 50 psi (3 bar) higher than the value in the chart is permitted. But pressure that is lower than the value in the chart is not permitted.
