Hydraulic System: Service and Repairs
If you are using a filter that is not the Toro high flow filter that is
bi-directional, do not press the traction pedal in the reverse direction.
If the flow is reversed when using a filter that is not bi-directional,
unwanted material from the filter will again enter the traction circuit.
11. With the engine running at high-idle speed, alternately move the traction
pedal from forward to reverse. While monitoring the filter indicator, continue
this process for 5 more minutes.
12. Shut off the engine and remove the key from the key switch.
13. Remove the high flow hydraulic filter and hydraulic hose kit from the machine.
Connect the pump inlet and balancing hoses to transmission fittings. Ensure
that you properly tighten the hoses; refer to
Tube (O-Ring Face Seal Fitting) (page
14. Repeat steps 4 through
15. After filtering is completed, lower the machine to the ground.
16. Check the hydraulic-fluid level in the hydraulic reservoir and add correct
quantity of fluid if necessary; refer to the Operator's Manual.
Note: When initially starting the hydraulic system with new or rebuilt components
such as wheel motors, gear pump, or lift cylinder, it is important that the hydraulic
system is charged properly. Remove the air from the system and its components
to reduce the chance of damage.
Change the hydraulic-fluid filter when you repair or replace the
hydraulic components.
1. Park the machine on a level surface and shut off the engine.
2. Ensure that all of the hydraulic connections, lines, and components are

Note: Flush and fill the hydraulic system and tank whenever there is a
severe component failure or the system is contaminated; refer to
the Hydraulic System (page
3. Ensure that the hydraulic tank is full. Add correct quantity of hydraulic fluid if
necessary; refer to the Operator's Manual.
4. Check the traction control components for proper adjustment, binding, or
damaged parts.
