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.
•
Ensure that all hydraulic-fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
•
Keep your body and hands away from pinhole
leaks or nozzles that eject high-pressure hydraulic
fluid.
•
Use cardboard or paper to find hydraulic leaks.
•
Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
Changing the Hydraulic
Fluid
Service Interval: Every 800 hours
Every 2 years—Drain and flush the hydraulic
tank.
If fluid becomes contaminated, contact your
authorized Toro distributor because the system must
be flushed. Contaminated fluid looks milky or black
when compared to clean oil.
1. Park the machine on a level surface, lower the
cutting units to the ground, shut off the engine,
and remove the key.
2. Raise the hood.
3. Place a large drain pan under the fitting secured
to the bottom of the hydraulic-fluid reservoir
(Figure 100).

4. Disconnect the hose from the bottom of the
fitting and let the hydraulic fluid flow into the
drain pan.
5. Install the hose when hydraulic fluid stops
draining.
6. Fill the reservoir with approximately 30 L (8 US
gallons) of hydraulic fluid; refer to
Hydraulic Fluid (page
Important:
Use only hydraulic fluids
specified. Other fluids could damage the
system.
7. Install the reservoir cap.
8. Start the engine and use all of the hydraulic
controls to distribute hydraulic fluid throughout
the system. Also, check for leaks.
9. Shut off the engine.
10. Check the level of the hydraulic fluid and add
enough to raise level to the F
dipstick.
Important:
Do not overfill the hydraulic
system.
