Note 1 shows "Hydraulic tank oil capacity at level gauge center."
Engine Use oil that meets engine oil classification API CH4, CI4 or CG4.
2: Change engine oil every 250 hours if CG4 is used.
Transmission Use engine oil classification API CD or A.T.F. (Auto Transmission Fluid).
Never mix engine oil and A.T.F.
Hydraulic System Use industrial-type hydraulic oils which are certified by suppliers having anti-wear, anti-foam,
anti-rust and anti-oxidation additive properties for heavy duty use. Use of the wrong viscosity
of oil can cause improper operation of hydraulic functions or premature pump failure.
3. In a case that fire-resistant fluid is used in the hydraulic circuit, replace hydraulic pumps
Warning:
When operating in cold ambient temperatures (0 ºF/15 ºC or colder) ISO VG32 or equivalent
hydraulic oil use is recommended. When changing over to cold climate hydraulic oil (i.e. from
thicker ISO VG46 to thinner ISO VG32), brake system bleeding at each wheel hub will be
required to remove thicker oil and prevent delayed reaction of brake application and release.
Differential & Use class API CD engine oil with 5% "Antichatter" additive or friction modifier.
Planetary
Lubricating Grease Use multipurpose-type EP/MOLY grease for most applications.
NLGI NO.2 grease is suitable for most temperatures.
NLGI NO.1 or NO.0 grease for extremely low temperature.
Use lithium base grease for universal joints and a propeller shaft spline.
