Servicing the Hydraulic
System
Hydraulic Fluid Type: Toro
oil or Mobil
®
1 15W-50.
Important: Use fluid specified. Other fluids could
damage the hydraulic system.
Each Hydraulic System Fluid Capacity: 1.5 L (52 oz) per
side with filter change
Checking the Hydraulic Fluid
Service Interval: Every 50 hours—Check the hydraulic fluid
level.
1. Position the machine on a level surface.
2. Disengage the blade-control switch (PTO), move the
motion-control levers to the N
and set the parking brake.
3. Shut off the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Wait for the engine and hydraulic system to cool for
10 minutes.
Note: The oil level on the dipstick is incorrect if you
check the oil when the machine is hot.
5. Move the seat forward.
6. Clean the area around the dipsticks of the hydraulic
system reservoirs
(Figure
7. Remove 1 dipstick from the hydraulic reservoir
81).
8. Wipe the dipstick off and thread the dipstick into the
reservoir.
9. Remove the dipstick and look at the end
Note: If the oil level is at the add mark, slowly pour
only enough oil into the hydraulic reservoir to raise the
level to the full or H line.
Important: Do not overfill the hydraulic units
with oil, as damage may occur. Do not run the
machine with the oil below the add mark.
10. Install the dipstick.
11. Repeat procedure for the opposite dipstick.

WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• If hydraulic fluid is injected into the skin,
it must be surgically removed within a few
hours by a doctor familiar with this type
of injury. Gangrene may result if this is
not done.
• Keep your body and hands away from
pin hole 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.
• Make sure that all hydraulic fluid hoses
and lines are in good condition and that all
hydraulic connections and fittings are tight
before applying pressure to the hydraulic
system.
