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:
Note:
Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for
the hydraulic fluid is available in 20 ml (0.67 fl oz)
bottles. A bottle is sufficient for 15 to 22 L (4 to 6 US
gallons) of hydraulic fluid. Order Part No. 44-2500
from your authorized Toro distributor.
Important:
Toro Premium Synthetic
Biodegradable Hydraulic Fluid 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 gallon) pails or 208 L (55 US gallon) drums
from your authorized Toro distributor.

Check the hydraulic-fluid level.
The fluid level should be 1/2 way up the screen
in filler neck

If level is low, add the specified hydraulic fluid
to raise level.

Install the hydraulic-reservoir cap
Replacing the Hydraulic
Filter
Service Interval: Every 1,000 hours—If you
are using the recommended
hydraulic fluid, replace the
hydraulic filter.
Every 800 hours—If you are not using the
recommended hydraulic fluid or have ever
filled the reservoir with an alternative fluid,
replace the hydraulic filter.
