Hydraulic System
Maintenance

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.

Service Interval: Every 50 hours
1. Park the machine on a level surface, disengage
the PTO, and engage the parking brake.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3. All the machine to cool completely.
4. Check the fluid level on the side of the hydraulic
tank (Figure 62). Continue the procedure if the
level is below the cold fill level.
5. Clean the area around the cap of the hydraulic
tank (Figure 62).
6. Remove the cap from the filler neck and add
fluid to the reservoir until it reaches the cold fill
level (Figure 62).

Changing the Hydraulic
Fluid and Filters
Service Interval: After the first 50 hours—Change the
hydraulic-system filters and fluid.
Every 500 hours—After the initial
change—change the hydraulic-system
filters and fluid when using Toro
500 fluid. (Change it more often under dirty or
dusty conditions)
To replace the hydraulic fluid, the filters need to be
removed. Replace both at the same time; refer to
Hydraulic System Specifications (page 44)
specifications.
Removing the Filters and Draining
the Fluid
1. Park the machine on a level surface, disengage
the blade-control switch (PTO), and engage the
parking brake.
