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.

Hydraulic Fluid Specifications
Hydraulic Fluid Type: Toro
hydraulic fluid (preferred) or Mobil 1 15W-50 oil.
Important:
Use the fluid specified. Other fluids
could cause system damage.
Hydraulic System Capacity (with filters removed):
4.45 L (150 fl oz)
Checking the Hydraulic Fluid Level
Service Interval: Before each use or daily
1. Allow the hydraulic fluid to cool down. Check the
oil level when the fluid is cold.
2. Check expansion reservoir and if necessary
add Toro ® HYPR-OIL
FULL COLD line.

Changing the Hydraulic-System
Filters and Fluid
Service Interval: After the first 75 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 severe
conditions).
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 severe conditions).
Change the filters and fluid at the same time. Do
not use the fluid again. Purge any air in the system
after you install the new filters and add fluid. Refer to
Bleeding the Hydraulic System (page
Repeat the bleeding process until the fluid remains
at the F C line in the reservoir after purging.

Failure to properly perform this procedure can
result in irreparable damage to the transaxle drive
system.
Removing the Hydraulic-System Filters
1. Park the machine on a level surface, disengage
the blade-control switch (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. Allow the engine to cool.
