Servicing the Hydraulic
System
Hydraulic Oil Type: Toro ® HYPR-OIL ™ 500
hydraulic oil or Mobil ® 1 15W-50
Hydraulic System Oil Capacity: 132 ounces (3.9l)
Important:
Use oil specified. Other fluids could
cause system damage.
Checking the Hydraulic Fluid Level
Service Interval: After the first 8 hours
Every 25 hours
Important:
Use oil specified or equivalent. Other
fluids could cause system damage.
Note:
There are two ways of checking the hydraulic oil.
One is when the oil is warm and one is when the oil is
cold. The baffle inside the tank has two levels depending
if the oil is warm or cold.
1. Position the machine on a level surface and set the
parking brake.
2. Clean the area around filler neck of hydraulic tank
(Figure 75).
3. Remove the cap from the filler neck. Look inside to
check if there is fluid in the reservoir (Figure 75).
4. If there is no fluid, add fluid to the reservoir until it
reaches the cold level of the baffle.
5. Run the machine at low idle for 15 minutes to allow
any air to purge out of the system and warm the fluid.
Refer to Starting and Stopping the Engine (page 20).
6. Recheck the fluid level while the fluid is warm. The
fluid should be between cold and hot.
7. If required, add fluid to the hydraulic tank.
Note:
The fluid level should be to the top of the hot
level of the baffle, when the fluid is hot (Figure 75).
8. Install cap on filler neck.

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 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 all hydraulic fluid hoses and
lines are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to hydraulic system.
