3 - 36 S-40 • S-45 Part No. 102521October 2013Section 3 • Scheduled Maintenance ProceduresCHECKLIST C PROCEDURESC-2Grease the Platform OverloadMechanism (if equipped)Genie specifications require that this procedure beperformed every 500 hours or 6 months, whichevercomes first. Perform this procedure more often ifdusty conditions exist.Application of lubrication to the platform overloadmechanism is essential to safe machine operation.Continued use of an improperly greased platformoverload mechanism could result in the system notsensing an overloaded platform condition and willresult in component damage.1 Locate the grease fittings on each pivot pin ofthe platform overload assembly.2 Thoroughly pump grease into each greasefitting using a multi-purpose grease.Grease typeChevron Ultra-duty grease, EP NLGI 2 (lithium based)or equivalentC-3Test the Platform OverloadSystem (if equipped)Genie specifications require that this procedure beperformed every 500 hours or six months,whichever comes first.Testing the platform overload system regularly isessential to safe machine operation. Continued useof an improperly operating platform overloadsystem could result in the system not sensing anoverloaded platform condition. Machine stablitycould be compromised resulting in the machinetipping over.Note: Perform this procedure with the machine on afirm, level surface.1 Turn the key switch to platform control. Start theengine and level the platform.2 Determine the maximum platform capacity.Refer to the machine serial plate.3 Remove all weight, tools and accessories fromthe platform.Note: Failure to remove all weight, tools andaccessories from the platform will result in aninaccurate test.4 Using a suitable lifting device, place a testweight equal to that of the available capacity atone of the locations shown.Refer to Illustration 1.Result: The platform overload indicator lightsshould be off at both the ground and platformcontrols and the alarm should not sound.Result: The platform overload indicator lights areon and the alarm is sounding. Calibrate theplatform overload system. Refer to RepairProcedure 2-4,How to Calibrate the PlatformOverload System (if equipped).Property of American Airlines
