High Viscosity Index/Low Pour Point
Anti-wear Hydraulic Fluid, ISO VG 46 (cont'd.)
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 fluid is available in 20 ml (2/3 fl oz)
bottles. A bottle is sufficient for 15 to 22 L (4 to 6 US
gallons) of hydraulic fluid. Order Part No. 44-2500
from your authorized Toro distributor.

wipe it with a clean cloth
4. Insert the dipstick into the hydraulic tank.
5. Remove the dipstick and check the fluid level

If you have a cutting unit equipped: The
hydraulic-fluid level is at the appropriate level
when the fluid appears between the lower 2
marks on the dipstick (A in
also acceptable for the fluid level to be above
the lower marks.

If you have the auxiliary hydraulic kit
equipped: The hydraulic-fluid level is at
the appropriate level when the fluid appears
between the upper 2 marks on the dipstick

6. If the fluid level is below the appropriate lower
mark (per your equipped attachment; refer
to step 5) on the dipstick, add the specified
hydraulic fluid into the tank. Repeat steps
through
the appropriate 2 marks on the dipstick.
7. Insert the dipstick and plug into the hydraulic
