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.

Changing the Hydraulic
Fluid and Filters
Service Interval: After the first 75 hours—Change the
hydraulic-system filters and fluid.
Every 250 hours—After the initial
change—change the hydraulic-system
filters and fluid when using Mobil 1 15W50
fluid. (Change it more often under dirty or dusty
conditions)
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 Fluid Specifications (page 53)
specifications.
Purge any air in the system after you install the new
filters and add fluid. Refer to
System (page
55). Repeat the bleeding process until
the fluid remains at the F
after purging. Failure to properly perform this
procedure can result in irreparable damage to the
transaxle drive system.
