Checking The Hydraulic System - Toro 30807 Operator's Manual

1. Access panel
2. Radiator
The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol anti-freeze. Check the coolant
level at the beginning of each day before starting the engine.
The capacity of the cooling system is approximately 5.7 liters
(6 quarts).
CAUTION
If the engine has been running, the pressurized, hot
coolant can escape and cause burns.
• Do not open the radiator cap when the engine
is running.
• Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.
1. Check the coolant level in the expansion tank (Figure
29). With a cold engine, the coolant level should be
approximately midway between the marks on the side
of the tank.
2. If the coolant level is low, remove the expansion tank
cap and replenish the system. Do not overfill.
3. Install the expansion tank cap.

Checking the Hydraulic
System
Service Interval: Before each use or daily—Check the
hydraulic fluid level.
The machines reservoir is filled at the factory with
approximately 13.2 liters (3.5 U.S. 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 Toro Premium All
Season Hydraulic Fluid (Available in 19 liter (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. Toro does
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, 65° F (18° C) to 120° F
(49° C), ISO VG 68 hydraulic fluid may offer improved
performance.
