Check the level of thehydraulic fluid before you start the engine for the firsttime, and daily thereafter.Use Toro Premium All-season Hydraulic Fluid (availablein 5-gallon pails or 55-gallon drums. See the parts catalog oran Authorized Toro Service Dealer for part numbers).If Toro hydraulic fluid is not available, you may use anequivalent hydraulic fluid, provided that it meets all thefollowing material properties and industry specifications. Donot use a synthetic hydraulic fluid. Consult with yourlubricant distributor to identify a satisfactory product.Note: Toro does not assume responsibility for damagecaused by improper substitutions, so use only products fromreputable manufacturers.High Viscosity Index/Low Pour Point Anti-wearHydraulic Fluid, ISO VG 46Material Properties:St @ 40°C (104°F): 44 to 48Viscosity, ASTM D445St @ 100°C (212°F): 7.9 to 8.5Viscosity Index ASTMD2270140 to 160Pour Point, ASTM D97 -37°C (-34°F) to -45°C (-49°F)FZG, Fail stage 11 or betterWater content (new fluid) 500 ppm (maximum)Industry Specifications: Vickers I-286-S (Quality Level),Vickers M-2950-S (QualityLevel), Denison HF-0Note: Many brands of hydraulic fluids are almost colorless,making it difficult to spot leaks. A red dye additive for thehydraulic system oil is available in 20 ml (0.68 oz) bottles.One bottle is sufficient for 15.1 to 22.7 L (4.0 to 6.0 US gal)of hydraulic oil.
