Checktheconnectionbetweenthealuminiumoorboardsandtheoorsystemfortightnessoftheoorbolts.
Thischeckmusttakeplaceaftertherstloading/unloading,afterapproximately10timesloading/unloading
andafteramonth.Iftheboltmountingoftheoorplanksisnotcorrect,adifferencewilloccurintheforces
transmittedtotheoorsystembytheoorplanks,whichinturncanleadtodamagetothedriveunit.
