12.10.HYDRAULICOILLEVELCHECK
Checktheoillevelonindicator;theoilmustbehalfwayupthelevelindicator.If
thisisnotthecase,topupthroughtherelativecap.Forthecharacteristicsofthe

.CHECKINGFORLEAK SINTHEHYDRAULICSYSTEM
Visuallycheckallhoses,connectionsandallothercomponentsinthehydraulic
system,inordertoidentifyanypossibleleaks.Leaksfromhosescannormallybe
resolvedbytighteningthefittings.Leaksfromgaskets(Orings,sealing ringsetc.)
cannotbe eliminatedbysimplytightening,asgask
etsusuallyleakbecausethey
aredamagedorhavebecomehard.Thecorrecttightnesscanonlyberestoredby
replacingthegasket.
12.12.CHECKINGTHECONDITIONOFTHEFILTERCARTRIDGE
Thecartridgemustbereplacedoneveryoilchangeandaccordingtotheintervals
specifiedinthemaintenancetable.
Thecheckmustbecarriedoutwiththemachi
neandthestabilisersinthere‐
stingpositiononflatground.
