Changing the Hydraulic Oil and
Filter
Normally, change the hydraulic oil and filter after every
2000 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.
1.
Remove the drain plug from the reservoir (Fig. 41) and
let hydraulic oil flow into a drain pan. Reinstall and
tighten the plug when hydraulic oil stops draining.

2.
Clean the area around the filter mounting area (Fig. 42).
Place a drain pan under the filter and remove the filter.

3.
Fill the replacement filter with hydraulic fluid; refer to
Servicing the Hydraulic System, page 17. Lubricate the
sealing gasket, and hand turn the filter until the gasket
contacts the filter head. Tighten the filter 3/4 turn
further. The filter should now be sealed.
4.
Fill the hydraulic tank with approximately 4.5 gallons
of hydraulic oil; refer to Servicing the Hydraulic
System, page 17.
5.
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.
6.
Dispose of the used oil properly.
Checking the Hydraulic Lines
and Hoses
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.
Warning
Check 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.
Adjusting the Brakes
A brake adjustment rod is located on each side of the
machine so that the brakes can be equally adjusted. Adjust
the brakes as follows:
1.
Transport the machine and depress the brake pedal; both
wheels should lock equally.
