Hydraulic System Management Guide

PreventionControlcontaminationduring generalmaintenanceEarlier we discussed the importance offollowing recommended oil and filterchange intervals. A few other preventiontips include:Perform daily inspectionsWhen performing the daily inspections,check for leaks and promptly fix any youfind. Look especially for worn cylinderwiper seals and pitted rods that may begiving dirt and other contaminants a freepass into the system.Keep hydraulic tanks filledAlways keep the hydraulic tank between“Full” and “Add.” Insufficient fluid levelsare the leading cause of pump cavitation,leading to pump failure and contaminationof the entire system. Low fluid levels canalso result in high oil temperatures,causing oil to degrade.Maintain valvesMaintain oil cooler and relief valvesproperly. Relief valve settings should beadjusted only by our trained technicians.If a pressure loss is detected, it’simportant to find its source and repair it.Replace worn fan beltsInspect fan belts, radiators and oilcoolers regularly. Maintaining fan speedand cleaning debris from radiators andoil coolers will help keep the systemoperating at acceptable temperatures.10
