Checking the Hydraulic
Lines and Hoses
Service Interval: Before each use or daily
Check the hydraulic lines and hoses for leaks, kinked
lines, loose mounting supports, wear, loose fittings,
weather, deterioration, and chemical deterioration.
Make all necessary repairs before operating the
machine.
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• 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 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.
• Seek immediate medical attention if fluid
is injected into skin.
Servicing the Hydraulic
Fluid and Filter
Service Interval: Every 1,000 hours—If you
are using the recommended
hydraulic fluid, replace the
hydraulic filter.
Every 2,000 hours—If you are using the
recommended hydraulic fluid, change the
hydraulic fluid and filter.
Every 800 hours—If you are not using the
recommended hydraulic fluid or have ever
filled the reservoir with an alternative fluid,
change the hydraulic fluid and filter.
Changing the Hydraulic Fluid
Important:
If the fluid becomes contaminated,
contact an authorized Toro distributor.
Contaminated fluid looks milky or black when
compared to clean fluid.
1.
Turn the engine off.
2.
Disconnect the small hydraulic hose (case drain)
from the bottom of the reservoir and let the
hydraulic fluid flow into a drain pan.
Note:
Install and tighten the hose when the
hydraulic fluid stops draining.
3.
Fill the reservoir with approximately 38 L (10 US
gallons) of hydraulic fluid. Refer to
Hydraulic Fluid (page
Important:
Use only the hydraulic fluids
specified. Other fluids could damage the
system.
To prevent over filling, do not fill if the fluid
is cold. Do not over fill.
4.
Install the reservoir cap.
5.
Start the traction unit engine, use all the
hydraulic controls to distribute the hydraulic fluid
throughout the system, and check for leaks.
6.
Shut off the engine
7.
With the fluid warm, look into the sight gauge.
Note:
If the hydraulic fluid level is low, add
enough fluid to raise the level to the middle
(maximum) of the sight gauge.
Replacing the Hydraulic Filter
Use only the Toro replacement filter (Part No.
54-0110) in the hydraulic system.
Important:
Use of any other filter may void the
warranty on some components.
1.
Turn the traction unit engine off and remove the
key from the ignition.
