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

DANGER
In certain conditions during fueling, static
electricity can be released causing a spark which
can ignite the gasoline vapors. A fire or explosion
from gasoline can burn you and others and can
damage property.
• Always place gasoline containers on the ground
away from your vehicle before filling.
• Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior carpets
or plastic truck bed liners may insulate the
container and slow the loss of any static charge.
• When practical, remove gas-powered equipment
from the truck or trailer and refuel the equipment
with its wheels on the ground.
• If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a gasoline dispenser
nozzle.
• If a gasoline dispenser nozzle must be used,
keep the nozzle in contact with the rim of the
fuel tank or container opening at all times until
fueling is complete.
1. Clean around the fuel tank cap and remove it (Figure
29).

1. Fuel tank cap
2. Add unleaded regular gasoline to the fuel tank until the
level is 25 mm (1 inch) 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 22.7 L (6 US gallons ).
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 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
