Checking the Hydraulic Fluid
Service Interval: Before each use or daily
The machines reservoir is filled at the factory with
approximately 29.3 liters (7.75 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
18.9 liter (5 gallon) pails or 208 liter (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.

Anti-wear Hydraulic Fluid, ISO VG 46
Material Properties:
Viscosity, ASTM D445
Viscosity Index ASTM D2270
Pour Point, ASTM D97
Industry Specifications:
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 liters (4-6 gallons ) of hydraulic oil. Order
part no. 44-2500 from your authorized Toro distributor.
