Hydraulic Oil

Service Interval/Specification
Change the hydraulic oil after every 800 operating hours.
If the oil becomes contaminated, contact your local Toro
distributor because the system must be flushed.
Contaminated oil looks milky or black when compared to
clean oil.
Change the filter:
After the first 50 operating hours
After every 800 operating hours
Changing the Hydraulic Oil and Filter
1. Clean the area around the filter mounting area (Fig. 48).
Place a drain pan under the filter and remove the filter.
Note: If the oil is not going to be drained, disconnect and
plug the hydraulic line going to the filter.

2. Fill the replacement filter with the appropriate hydraulic
fluid, lubricate the sealing gasket, and hand turn it until
the gasket contacts the filter head. Then tighten 3/4 turn
further. The filter should now be sealed.
3. Fill the hydraulic reservoir with approximately 5.5
gallons of hydraulic oil; refer to Servicing Hydraulic
System Fluid, page 21.
4. Start the machine and run it at idle for 3 to 5 minutes to
circulate the fluid and remove any air trapped in the
system. Stop the machine and recheck the fluid level.
5. Dispose of the oil properly.
Checking the Hydraulic Lines
and Hoses
Inspect the hydraulic lines and hoses daily for leaks, kinked
lines, loose mounting supports, wear, loose fittings, weather
deterioration and chemical deterioration. Make all
necessary repairs before operating.
Warning
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
Make sure 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 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.
Get immediate medical help if fluid is injected
into skin.

Adjusting the Brakes

A brake adjustment rod is located on each side of the
machine so the brakes can be equally adjusted. Adjust the
brakes as follows:
1. Drive the machine and depress the brake pedal; both
wheels should lock equally.
Caution
Testing the brakes in a confined area where others
are present could cause injury.
Always check the brakes in a wide, open-spaced,
flat area which is free of other persons and
obstructions before and after adjustment.
