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.
Servicing the Hydraulic
Fluid
Important:
Regardless of the hydraulic fluid type
that you use, any machine used for off-green
applications, verticutting or used during ambient
temperatures above 29°C (85°F), install the Oil
Cooler Kit (Part No. 104-7701); refer to
the Oil Cooler (page
Hydraulic Fluid Specifications
The hydraulic-fluid reservoir is filled at the factory with
approximately 20.8 L (5.5 US gallons) of high quality
hydraulic fluid. Check the level of the hydraulic fluid
before operating the machine each day. If the fluid
is low, add an appropriate fluid as described in the
following sections:
Toro Premium All Season Hydraulic Fluid (Available in 5
gallon pails or 55 gallon drums. See your machine Parts
Catalog or you authorized Toro distributor for part numbers)
Alternate fluids: If the Toro fluid is not available,
other fluids may be used, provided that they meet
all the following material properties and industry
specifications. The use of synthetic fluid is not
recommended. Consult with your lubricant distributor
to identify a satisfactory product
Note:
Toro will not assume responsibility for damage
caused by improper substitutions, so use only
products 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:
Vickers I-286-S (Quality Level), Vickers M-2950-S
(Quality Level), Denison HF-0
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 gallon) containers or 208 L (55 US 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 oil is available in 20 ml (0.67 oz)
bottles. One 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. This red dye
is not recommended for use with biodegradable
fluids. Use food coloring.
