1. Hydraulic-pressure filter
5. Discard the old filter.
6. Apply a thin layer of hydraulic oil to the o-ring of the
filter.
7. Install and tighten the new filter with a filter wrench.
8. Start the engine, let it run idle for approximately
1 minute, then check for leaks around the
hydraulic-pressure filter.
Changing the Hydraulic Fluid
Service Interval: Every 1,000 hours/Yearly (whichever
comes first)
Important: If the fluid becomes contaminated, contact
your Authorized Toro Dealer, because the system must
be flushed. Contaminated fluid looks milky or black
when compared to clean oil.
Important: Use of any other filter may void the warranty
on some components.
1. Park the machine on a level surface, stop the engine,
and remove the ignition key.
2. Open the front hood.
3. Raise the machine using proper equipment.
WARNING
Raising the rear of the unit relying solely
on mechanical or hydraulic jacks could be
dangerous. The mechanical or hydraulic
jacks may not be enough support or may
malfunction allowing the unit to fall, which
could cause injury or death.
Do not rely solely on mechanical or hydraulic
jacks for support.
Use adequate jack stands or equivalent
support.
4. Place a large draining container under the hydraulic
fluid tank.
5. Remove the drain plug from the bottom of the tank.
6. Clean the threads on the drain plug and apply 3 layers
of PTFE sealing tape.
7. Drain the hydraulic fluid flow into the container.
Important: The capacity of the hydraulic-fluid
tank is 102 L (27 US gallons), so ensure that you
have a container of at least 114 L (30 US gallons)
to drain the fluid into.
8. Install the drain plug when the hydraulic fluid stops
draining.
9. Clean the area around the filter mounting areas.
10. Place a drain pan under the filter and remove the filter
(Figure
109).
11. Lubricate the filter gasket of each new filter and fill
them with hydraulic fluid.
12. Ensure that the filter mounting areas are clean.
13. Screw the filters on until the gaskets contacts the
mounting plates; then tighten the filter an additional
1/2 turn.
14. Fill the reservoir with hydraulic fluid.
Important: Use only the hydraulic fluids
specified. Other fluids could cause system
damage.
15. Install the reservoir cap. Start the engine and use all
of the hydraulic controls to distribute hydraulic fluid
throughout the system. Also check for leaks; then stop
the engine.
16. Check the fluid level and add enough to raise level the
level to the Full mark on the dipstick. Do not overfill.
