Hydraulic System Safety

•
Seek immediate medical attention if fluid is injected
into skin. Injected fluid must be surgically removed
within a few hours by a doctor.
•
Before disconnecting or performing any work on
the hydraulic system, relieve all pressure in the
system by shutting off the engine, cycling the
dump valve from raise to lower, and/or lowering
the cargo bed and attachments. Place the remote
hydraulics lever in the float position. Do not work
under a raised bed without the proper bed safety
support in place.
•
Ensure that all hydraulic-fluid hoses and lines are
in good condition and that all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
•
Keep your hands and body away from pinhole
leaks or nozzles that eject high-pressure hydraulic
fluid.
•
Use cardboard or paper to find hydraulic leaks.

Hydraulic Fluid Specifications
The reservoir is filled at the factory with high-quality
hydraulic fluid. Check the level of the hydraulic fluid
before you first start the engine and daily thereafter;
refer to Checking the Hydraulic-Fluid Level (page
Recommended replacement 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 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:
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.

1. Park the machine on a level surface.
2. Engage the parking brake.
3. Shut off the engine and remove the key.
4. Clean the area around the filler neck and the
cap of the hydraulic reservoir
