Checking The Hydraulic-Fluid Level - Toro 04530 Operator's Manual

Checking the Hydraulic-Fluid
Level
The hydraulic-fluid reservoir is filled at the factory with
approximately 18.9 L (5 US gallons) of high quality hydraulic
fluid. Before operating the machine each day, check level of
the hydraulic fluid in the white plastic window on the front of
the hydraulic-fluid reservoir (behind the seat on the left side).
The fluid should be between the lines in the window; if not,
add an appropriate fluid as described in the following sections:
The recommended replacement fluid is as follows:
Toro Premium All Season Hydraulic Fluid (Available in
5-gallon pails or 55-gallon drums. See parts catalog or
Toro distributor for part numbers.)
Alternate fluids: If the Toro fluid is not available, other fluids
may be used provided they meet all the following material
properties and industry specifications. We do not recommend
the use of synthetic fluid. 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, Vickers 35 VQ (Eaton
ATS373-C)
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 gallon) 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 oil is available in 20 ml (2/3 oz) bottles. One bottle
is sufficient for 15-22 L (4-6 gallons) of hydraulic oil. Order
part no. 44-2500 from your authorized Toro distributor. This
red dye is not recommended for use with biodegradable
fluids. Use food coloring.
Important: Regardless of the hydraulic fluid type used,
any machine used for off green applications, verticutting
or used during ambient temperatures above 29° C (85° F)
should have Oil Cooler Kit installed; refer to
the Optional Oil Cooler (page
Filling the Hydraulic Tank
1. Position the machine on a level surface. Make sure the
machine has cooled down so the oil is cold.
2. Remove the cap from the reservoir

3. Slowly fill the reservoir with the appropriate hydraulic
fluid until the level is at or within 6 mm (1/4 inch) of
the arrow in the symbol next to the white window in

Important: To prevent system contamination,
clean the top of the hydraulic fluid containers
before puncturing. Ensure the pour spout and
