Checking The Tire Pressure - Toro 04358 Greensmaster 3150 Operator's Manual

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 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
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 1 (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 traction unit used for off green applications,
verticutting or used during ambient temperatures above
cSt @ 40°C 44 to 48
cSt @ 100°C 7.9 to 8.5
140 to 160
-34°F to -49°F
29° C (85° F) should have Oil Cooler Kit, Part No.
105-8339, installed.
1. Position the machine on a level surface. Make sure the
machine has cooled down so the oil is cold. Check
the oil level by viewing the sight window on the side
of the auxiliary oil tank (Figure 22). If the oil level is
between the two marks on the sight window, the oil
level is sufficient.
2. If the oil level is below the bottom mark in the sight
window, remove the cap from the hydraulic oil tank
and slowly fill the tank with the appropriate high quality
hydraulic fluid until the level is between the two marks
on the sight window. Do not mix oils. Install the cap.
Important: To prevent system contamination,
clean the top of the hydraulic oil containers before
puncturing them. Ensure that the pour spout and
funnel are clean.
Note: Make a close visual inspection of the hydraulic
components. Inspect them for leaks, loose fasteners,
missing parts, improperly routed lines, etc. Make any
corrections necessary.

Checking the Tire Pressure

The tires are over-inflated at the factory for shipping
purposes. Reduce the pressure to the proper levels before
starting the unit.
Vary the tire pressure for the front wheels, depending
upon your turf conditions, from a minimum of 55 kPa to a
maximum of 83 kPa (8 to 12 psi).
Vary the tire pressure for the rear wheel from a minimum of
55 kPa to a maximum of 103 kPa (8 to 15 psi).
