3 - 10 Genie Z-60/34 Part No. 75861November 2003Section 3 • Scheduled Maintenance ProceduresREV AA-8Test the Oscillate Axle(if equipped)Proper axle oscillation is essential to safe machineoperation. If the axle oscillation system is notoperating correctly, the stability of the machine iscompromised and it may tip over.1 Start the engine from the platform controls.2 Drive the right steer tire up onto a 6 inch /15.2 cm block or curb.Result: The three remaining tires should stay infirm contact with the ground and the chassisshould remain level at all times.3 Drive the left steer tire up onto a 6 inch /15.2 cm block or curb.Result: The three remaining tires should stay infirm contact with the ground and the chassisshould remain level at all times.If the chassis does not remainlevel during test, refer to RepairProcedure 8-6, How to Set Up theDirectional Valve Linkage.4 Drive both steer tires up onto a 6 inch /15.2 cm block or curb.Result: The non-steer tires should stay in firmcontact with the ground.A-7Check the High PressureHydraulic Filter ConditionIndicator (if equipped)Maintaining the high pressure hydraulic filter ingood condition is essential to good systemperformance and safe machine operation. The filtercondition indicator will show when the hydraulic flowis bypassing a clogged filter. If the filter is notfrequently checked and replaced, impurities willremain in the hydraulic system and causecomponent damage.1 Open the engine side turntable cover.2 Start the engine from the ground controls.3 Change the engine idle to high rpm (rabbitsymbol).4 Visually inspect the filter condition indicator.Result: The filter condition indicator should beoperating with the plunger in the green area. Ifthe indicator displays the plunger in the redarea, this indicates that the hydraulic filter isbeing bypassed and the filter should bereplaced. See B-21, Replace the HydraulicFilters.CHECKLIST A PROCEDURES
