Checking The Hydraulic-Fluid Level; Checking The Tire Pressure - Toro Groundsmaster 4500-D Operator's Manual

Note:
If possible, fill the fuel tank after each use; this
will minimize possible buildup of condensation inside
the fuel tank.
Checking the
Hydraulic-Fluid Level
Service Interval: Before each use or daily
The machines reservoir is filled at the factory with
approximately 28.4 L (7.50 US gallons) of high quality
hydraulic fluid. Check the level of the hydraulic fluid
before the engine is first started and daily thereafter.
The recommended replacement fluid is as follows:
Toro Premium All Season Hydraulic Fluid (Available in 18.9
L (5 US gallons) pails or 208 L (55 US gallons) drums. See
the Parts Catalog or your 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:
Use products only from reputable
manufactures. Toro does not take responsibility for
damage caused by improper substitutions.
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
cSt @ 40°C 44 to 50
cSt @ 100°C 7.9 to 8.5
140 to 160
-34°F to -49°F
US gallons) containers or 208 L (55 US gallons)
drums from your Mobil Distributor.
Important:
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. 1 bottle is
sufficient for 15 to 22 L (4 to 6 US gallons) of
hydraulic oil. Order Part Number 44-2500 from
your Toro Distributor.
1. Position the machine on a level surface, lower
the cutting units, turn the key in the ignition
switch to the O
2. Clean the area around the filler neck and cap of
the hydraulic tank

3. Remove the dipstick, wipe it clean, install the
dipstick into the tank, and pull it out again.
Note:
The fluid level should be between the 2
marks on the dipstick.
4. If the level is low, add the appropriate fluid to
raise the level to the upper mark.
5. Install the dipstick and cap onto the filler neck.

Checking the Tire Pressure

Service Interval: Before each use or daily
The tires are over-inflated for shipping. Therefore,
release some of the air to reduce the pressure. The
correct air pressure in the tires is 138 kPa (20 psi).
Important:
Maintain the recommended
pressure in all tires to ensure that there is a
good quality-of-cut and for proper machine
performance. Do not under-inflate.
