1. Hydraulic-tank cap
3. Remove the cap.
4. Remove the dipstick from the filler neck and
wipe it with a clean rag. Insert the dipstick into
the filler neck; then remove it and check the fluid
level. The fluid level should be within 6 mm (1/4
inch) of the mark on the dipstick.
5. If the level is low, add the appropriate fluid to
raise the level to the full mark.
6. Install the dipstick and cap onto the filler neck.

Recommended hydraulic fluid: Toro PX Extended
Life Hydraulic Fluid; available in 19 L (5 US gallon)
pails or 208 L (55 US gallon) drums.
Note:
A machine using the recommended
replacement fluid requires less frequent fluid and filter
changes.
Alternative hydraulic fluids: If Toro PX Extended
Life Hydraulic Fluid is not available, you may use
another conventional, petroleum-based hydraulic fluid
having specifications that fall within the listed range
for all the following material properties and that it
meets industry standards. Do not use synthetic fluid.
Consult with your lubricant distributor to identify a
satisfactory product.
Note:
Toro does not assume responsibility for
damage caused by improper substitutions, so use
products only 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:
g008886
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 (0.67 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.
Important:
Toro Premium Synthetic
Biodegradable Hydraulic Fluid 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 19 L
(5 US gallon) pails or 208 L (55 US gallon) drums
from your authorized Toro distributor.
