High Viscosity Index/Low Pour Point Anti-wear Hydraulic
Fluid, ISO VG 46 Multigrade
Material Properties:
Viscosity, ASTM D445
Viscosity Index ASTM D2270
Pour Point, ASTM D97
FZG, Fail stage
Water content (new fluid):
Industry Specifications:
Vickers I-286-S, Vickers M-2950-S, Denison HF-0,
Vickers 35 VQ 25 (Eaton ATS373-C)
The proper hydraulic fluids must be specified for
mobile machinery (as opposed to industrial plant
usage), multiweight-type, with ZnDTP or ZDDP
anti-wear additive package (not an ashless-type fluid).
Note:
Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for
the hydraulic system fluid is available in 20 ml (2/3
fl oz) bottles. One bottle is sufficient for 15 to 22 L
(4 to 6 US gallons) of hydraulic fluid. Order Part No.

3.
Remove the hydraulic-tank cap and check the
fluid level on the dipstick
Note:
The fluid level should be between the
upper limit and the lower limit on the dipstick
(Figure
21).

4.
If the fluid level is low, add enough fluid to raise
it to the proper level.
5.
Install the tank cap.
6.
Wipe up any spilled fluid.
7.
Lower and latch the seat.
Checking the Tire Pressure
Make sure that the transport tires are inflated to 103
kPa (15 psi).
