Lubricant Specifications
Lubricant Information
Some classifications and abbreviations we use in
this section follow S.A.E. (Society of automotive
Engineers) J754 nomenclature and others follow
S.A.E. J183.
All MIL specifications are U.S.A. Military.
Recommended oil viscosities are given in the
“Lubricant Viscosities” chart later in this section
of the manual.
Greases are classified according to the National
Lubricating Grease Institute (NLGI) based on ASTM
D217-68 worked Penetration characteristics which
give a defined consistency number.
Chain and Linkage Oils (DEO or
EO)
Use following engine oils are recommended for use
on chains and linkages.
European oil specification CCMC D3.
API Specification CD, CD/SF, CE
Military specifications MIL-L-2104D or E
Hydraulic Oils (HYDO)
The following commercial classifications can be
used in the hydraulic system.
ISO 6743/4 HM
AFNOR NFE 48-603 HM
DIN 51524 TEIL 2 H-LP
HAGGLUNDS DENISON HFO-HF2
CINCINNATI P68, 69, 70
Viscosity : ISO VG 32
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
Correct Hydraulic Oil should be used to achieve
maximum life and performance from hydraulic
system components. The following hydraulic Oil is
recommended in most hydraulic and hydrostatic
systems.
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.
