Hydraulic System
Maintenance

Hydraulic System Safety

•
Seek immediate medical attention if fluid is injected
into skin. Injected fluid must be surgically removed
within a few hours by a doctor.
•
Ensure that all hydraulic-fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
•
Keep your body and hands away from pinhole
leaks or nozzles that eject high-pressure hydraulic
fluid.
•
Use cardboard or paper to find hydraulic leaks.
•
Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
Checking the Hydraulic
Lines and Hoses
Service Interval: Before each use or daily
Check the hydraulic lines and hoses for leaks, kinked
lines, loose mounting supports, wear, loose fittings,
weather deterioration, and chemical deterioration.
Make all necessary repairs before operating.
Hydraulic Fluid
Specifications
The reservoir is filled at the factory with high-quality
hydraulic fluid. Check the level of the hydraulic fluid
before you first start the engine and daily thereafter;
refer to Checking the Hydraulic Fluid (page
Recommended hydraulic fluid: Toro PX Extended
Life Hydraulic Fluid; available in 19 L (5 US gallon)
pails or 208 L (55 US gallon) drums.
Note:
A machine using the recommended
replacement fluid requires less frequent fluid and filter
changes.
Alternative hydraulic fluids: If Toro PX Extended
Life Hydraulic Fluid is not available, you may use
another conventional, petroleum-based hydraulic fluid
having specifications that fall within the listed range
for all the following material properties and that it
meets industry standards. Do not use synthetic fluid.
Consult with your lubricant distributor to identify a
satisfactory product.
Note:
Toro does not assume responsibility for
damage caused by improper substitutions, so use
products only from reputable manufacturers who will
stand behind their recommendation.
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:
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.

The reservoir is filled at the factory with high-quality
hydraulic fluid. The best time to check the hydraulic
oil is when the fluid is cold. The machine should be in
its transport configuration.
