Lubricant Specifications
Lubricant Information
Certain abbreviations follow Society of Automotive
Engineers (SAE) J754 nomenclature and some
classifications follow SAE J183 abbreviations.
The MIL specifications are U.S.A. Military Specifications.
The recommended oil viscosities can be found in the
Lubricant Viscosities chart in this publication.
Grease is classified by the National Lubricating Grease
Institute (NLGI) based on ASTM D217-68 Worked
Penetration characteristics which are given a defined
consistency number.
Engine Oil (DEO and EO)
The following oil specifications provide guidelines for the
selection of commercial products :
• Gasoline/LP-Gas Engine : API SJ
• TIER I Diesel Engine (DB58 E/G)
: API CD Grade or higher, ACEA E2
• TIER II Diesel Engine (DB58S E/G)
: API CH-4 Grade, ACEA E5
NOTICE
Failure to follow the oil recommendations can
cause shortened engine lift due to carbon deposits
or excessive wear.
Consult the EMA Lubricating Oils Data Book for a listing
of oil brands.
NOTE: The percentage of sulfur in the fuel will affect
the engine oil recommendations. For fuel sulfur
effects, the Infrared Analysis or the ASTM
D2896 procedure can be used to evaluate the
residual neutralization properties of an engine
oil. The sulfur products formation depends on
the fuel sulfur content, oil formulation,
crankcase blowby, engine operating conditions
and ambient temperature.
Hydraulic Oil (HYDO)
The following commercial classifications can be used in
the hydraulic system.
z ISO 6743/4 HM
z AFNOR NFE 48-603 HM
z DIN 51524 TEIL 2 H-LP
z HAGGLUNDS DENISON HFO-HF2
z CINCINNATI P68,69,70
Viscosity : ISO VG 32
Industrial premium hydraulic oils that have passed the
Vickers vane pump test (35VQ25). These oils should
have antiwear, antifoam, antirust and antioxidation
additives for heavy duty use as stated by the oil supplier.
ISO viscosity grade of 32 would normally be selected.
NOTICE
Make-up oil added to the hydraulic tanks must mix
with the oil already in the systems. Use only
petroleum products unless the systems are
equipped for use with special products. If the
hydraulic oil becomes cloudy, water or air is
entering the system. Water or air in the system will
cause pump failure. Drain the fluid, retighten all
hydraulic suction line clamps, purge and refill the
system. Consult your DOOSAN Lift Truck dealer for
purging instructions.
