usingthehexheadcapscrewatthecenterofthecompressorclutchassembly.
3.Atregularintervals,checktheoillevel
atthesight‐glassuntilitreachesthespecifiedlevel.
4.Replacethefillplugortheinletcontrol valve.
5.Performaquickinspectionofthesystemtomakesurethatalllinesareonandtightandthatthefilter

2.Starttheengineandallowittoreachoperatingtemperature.
3.Turnthecompressorswitchonthecontrolunittothe“ON”position,allowthesystemtopressurize
andreturnto
presetbaseidlespeed.
4.Turnthecompressorswitchonthecontrolunittothe“OFF”position.
5.Allowthesystemtosettleforfiveminutes,andthenchecktheoillevelthroughthesightglass.The
