4. Check the coolant level in the radiator and in the
expansion tank.
Note: The radiator should be filled to the top of the
filler neck and the expansion tank filled to the Full
mark on the tank (Figure
5. If coolant level is low, remove the expansion tank cap
and the radiator cap, and fill expansion tank to the
Full mark and the radiator to the top of the filler neck
(Figure 20).
Important: Do not overfill the expansion tank.
Important: Do not use water only or an
alcohol/methanol-based coolant.
6. Install the radiator cap and the expansion tank cap
(Figure 20).
Checking the Hydraulic Fluid
Service Interval: Before each use or daily Check the level of
the hydraulic fluid before the engine is
first started and daily thereafter.
Hydraulic fluid specifications:
Toro Premium All Season Hydraulic Fluid
Note: (Available in 5-gallon pails or 55-gallon drums. See
parts catalog or Toro distributor for part numbers.)
Alternate hydraulic 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 5-gallon (19 L) containers or 55-gallon
drums from your Mobil Distributor.
1. Position the sprayer on a level surface, set the parking
