Hydraulic Fluid Capacity; Changing The Hydraulic Fluid; Replacing The Hydraulic Filters - Toro 03781TE Operator's Manual

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.

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 gallons) pails or 208 L (55 US gallons) from
your authorized Toro distributor.

Changing the Hydraulic
Fluid
Service Interval: Every 2,000 hours—If you
are using the recommended
hydraulic fluid, change the
hydraulic fluid.
Every 800 hours—If you are not using the
recommended hydraulic fluid or have ever
filled the reservoir with an alternative fluid,
change the hydraulic fluid.
If the fluid becomes contaminated, contact your local
authorized Toro distributor, because the system must
be flushed. Contaminated fluid looks milky or black
when compared to clean fluid.
1. Park the machine on a level surface, lower the
cutting units, engage the parking brake, shut off
the engine, and remove the key.
2. Raise the hood.
3. Disconnect the case return line from the bottom
of the reservoir and let the hydraulic fluid flow
into a large drain pan.
4. Connect the line when the hydraulic fluid stops
draining.
5. Fill the reservoir with hydraulic fluid; refer to
Hydraulic Fluid Specifications (page 56)

Important:
Use only the hydraulic fluids
specified. Other fluids could cause system
damage.
6. Install the reservoir cap.
7. Start the engine and use all of the hydraulic
controls to distribute hydraulic fluid throughout
the system.
8. Check for leaks and shut off the engine.
9. Check the fluid level and add enough to raise
the level to the Full mark on the dipstick.
Note:
Do not overfill the hydraulic system.
Replacing the Hydraulic
Filters
Service Interval: Every 1,000 hours—If you
are using the recommended
hydraulic fluid, replace the
hydraulic filters.
Every 800 hours—If you are not using the
recommended hydraulic fluid or have ever
filled the reservoir with an alternative fluid,
replace the hydraulic filters.
