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

Figure 28
1. Fuel tank cap
2. Add unleaded regular gasoline to the fuel tank until
the level is 1 inch (25 mm) below the bottom of the
filler neck.
This space in the tank allows gasoline to expand.
Do not fill the fuel tank completely full.
Note: The fuel tank capacity is 6 US gallons (22.7 ).
3. Install the fuel tank cap securely. Wipe up any
gasoline that may have spilled.
Checking the Hydraulic Fluid
Level
The hydraulic fluid reservoir is filled at the factory
with approximately 5 US gallons (18.9 l) 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 up to the full line in the window; if not, add an
appropriate fluid as described in the following sections:
Recommended Hydraulic Fluid
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, 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 oil is available in 5 gallon
(19 l) 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 2/3 oz. (20
ml) bottles. One bottle is sufficient for 4-6 gal (15-22
1) 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 traction unit used for off green
applications, verticutting or used during
ambient temperatures above 85° F (29° C)
should have Oil Cooler Kit installed; refer to
5 Installing the Optional Oil Cooler (page 16).
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 (Figure 29).
