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, 65°F
(18°C) to 120°F (49°C), 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 fluid is available in 19
L (5 US gallon) containers or 208 L (55 US gallon)
drums from your Mobil Distributor.
Important:
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.
1. Park the machine on a level surface, engage the
parking brake, lower the mower decks, shut off
the engine, and remove the key.
2. Check the hydraulic-fluid level
