Checking The Hydraulic Lines And Hoses; Inspecting The Hydraulic System Test Ports - Toro Groundsmaster 5900 Operator's Manual

hydraulic fluid, replace the
hydraulic filter (sooner if the service
interval indicator is in the red zone).
Every 800 hours—If you are not using the
recommended hydraulic fluid or have ever
filled the reservoir with an alternative fluid,
replace the hydraulic filter (sooner if the service
interval indicator is in the red zone).
If the hydraulic fluid becomes contaminated, contact
your authorized Toro distributor because the system
must be flushed. Contaminated fluid looks milky or
black when compared to clean fluid.
Use Toro replacement filters (Part No. 86-6110 for the
left side of the machine and Part No. 75-1310 for the
right side of the machine).
Important:
Using any other filter may void the
warranty on some components.
1. Park the machine on a level surface, engage the
parking brake, lower the cutting deck, shut off
the engine, and remove the key.
2. Clean the area around the filter-mounting areas.
3. Place a drain pan under the filter and remove
the filter (Figure 132).
4. Lubricate the new filter gasket and fill the filter
with hydraulic fluid.
5. Ensure that each filter-mounting area is clean
and screw the filter on until the gasket contacts
the mounting plate; then tighten the filter an
additional 1/2 turn.
6. Fill the reservoir with hydraulic fluid; refer to
Checking the Hydraulic Fluid (page
Important:
Use only the hydraulic fluids
specified. Other fluids could cause system
damage.
7. Install the reservoir dipstick and cap.
8. Start the engine and use all of the hydraulic
controls to distribute hydraulic fluid throughout
the system.
Note:
Also, check for leaks, then shut off the
engine.
9. Check the fluid level and add enough to raise
the level to the Full mark on the dipstick.
Note:
Do not overfill.

WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Seek immediate medical help if fluid is
injected into skin.
• Make sure 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 your body and hands away from
pinhole 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.
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 the machine.
