Engine
Use oil that meets engine oil classification API CH4 or CG4.
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.
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.
