Section 3 • Scheduled Maintenance Procedures3 - 10 S-100 • S-105 • S-120 • S-125 Part No. 102916June 2011REV BaA-6Check the Hydraulic FilterCondition IndicatorsGenie requires that this procedure be performeddaily.Note: Perform this procedure after the machinereaches operating temperature. The amount of timethis takes will vary, depending on ambient airtemperature.Maintaining the hydraulic filters in good condition isessential to good system performance and safemachine operation. The filter condition indicatorswill show when the hydraulic flow is bypassing aclogged filter. If the filters are not frequentlychecked and replaced, impurities will remain in thehydraulic system and cause component damage.Note: There are four hydraulic filters on themachine: one tank return filter, one mediumpressure filter and two high pressure filters. All thefilters have condition indicators on them, except themedium pressure filter.1 Start the engine from the ground controls.2 Press and release the engine idle select buttonto change the engine rpm to high idle.Tank return filterNote: The tank return filter indicator needle mayoperate in the red area when hydraulic oil is below50° F / 10° C.Note: If the return filter indicator needle is notoperating in the green area after performingprevious daily procedures, continue running engineuntil hydraulic oil temperature is at least50° F / 10° C.3 Open the ground control side turntable cover andinspect the filter condition indicator gauge.a filter condition indicator gaugeResult: The needle on the gauge should beoperating in the green area. If the needle is inthe red area, this indicates that the hydraulicfilter is being bypassed and the filter needs tobe replaced. See D-11,Replace the HydraulicFilter Elements.CHECKLIST A PROCEDURES
