High Viscosity Index/Low Pour Point
Anti-wear Hydraulic Fluid, ISO VG 46
Material Properties:
Viscosity, ASTM D445
Viscosity Index ASTM
D2270
Pour Point, ASTM D97
Industry Specifications:
Important:
The ISO VG 46 Multigrade fluid
has been found to offer optimal performance
in a wide-range of temperature conditions.
For operation in consistently high ambient
temperatures, 18°C (65°F) to 49°C (120°F),
ISO VG 68 hydraulic fluid may offer improved
performance.
Premium Biodegradable Hydraulic Fluid-Mobil
EAL EnviroSyn 46H
Important:
Mobil EAL EnviroSyn 46H is the only
synthetic biodegradable fluid approved by Toro.
This fluid is compatible with the elastomers used
in Toro hydraulic systems and is suitable for a
wide-range of temperature conditions. This fluid is
compatible with conventional mineral oils, but for
maximum biodegradability and performance the
hydraulic system should be thoroughly flushed of
conventional fluid. The oil is available in 19 L (5
US gallons) containers or 55 gallon drums from
your Mobil Distributor.
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 oz)
bottles. 1 bottle is sufficient for 15 to 22 L (4 to 6 US
gallons) of hydraulic fluid. Order Part No. 44-2500
from your Toro Distributor.
