Capthe fittings on the slave cylinder.Bodily injury hazard. Sprayinghydraulic oil can penetrate andburn skin. Loosen hydraulicconnections very slowly to allowthe oil pressure to dissipategradually. Do not allow oil tosquirt or spray.5 Pull the slave cylinder hydraulic hoses out ofthe protective sheath.6 Tag and disconnect the wiring from thejib boom/platform rotate manifold.7 Remove the cable clamp from the platformrotator.8 Remove the cable cover from the side of the jibboom.9 Tag, disconnect and plug the hydraulic hosesfrom the jib boom/platform rotate manifold.Cap the fittings on the jib boom/platform rotatemanifold.Bodily injury hazard.
