MaintainingtheVRSystem
Organizedmaintenancepracticeswillincreasethelifeexpectancyofthecompressorsystemand
maintainoperationwithinthemanufacturedparameters.VMAChasrecommendedserviceintervalsfor
theirsystemthatisbasedonactualtestingandperformance.TheVRsystemrequiresregular
maintenancethatincludes:
•inspectingandreplacingthedrivebelt
•
changingsystemoil
•changingfilters
•cleaningfilterscreens
Duringthewarrantyperiodyoumust followthemaintenancescheduleandonlyuseoriginalVMAC
replacementpartstomaintainthesystemandthewarranty.Periodicmaintenanceservicekitsare
availablefromVMAC.
Themostcriticalaspectofcompressoroperationis
properairfiltration.Contaminationenteringthe
intakecancausesevere,rapiddamagetorollerbearings,gearsandrotorsinthecompressor.
Neveroperatethetruck,thecompressororevenallowthetrucktoremainpar kedwithoutthe
recommendedairfilterandcoverinstalledonthecompressor.

Performingapre‐serviceinspection
Inspectthesystemcarefullyandcheckthefollowing:
•lookforleaksatthecompressor,cooler,tank,filterandlinefittings
•checkthecompressorandbrackettomakesurethattheyaretightandsecure
•checkthecoolertomakesurethatitistightandsecure
•check
thetankbracketsandtankmountingtomakesurethattheyarenotloose
•checkallfastenersforevidenceofmotionorvibrationloosening
•examineallthelinesforevidenceofrubbing,chafingorotherenvironmentaldamage
•usingtheappropriatetools,checkallthelinefittingsto
makesurethattheyaretight
•checkelectricalconnectionsforsecurity

•checkallwiringforsecurityanddamage
•checkthecontrolunitstomakesurethattheyaresecure
Ifyoudiscoveranyproblems,performthenecessaryrepairstopreventfurtherdamage.Protectall
wiring,lines,connections
andfittingsasrequired.Tightenanyloosefastenersandreplaceanydamaged
