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 on page 22.
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 (Fig. 51).
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.
Replacing the Hydraulic Filter
Change the hydraulic filter:
3
m–5615
3. Cold fluid level—full
4. Hot fluid level—full
41
After the first 8 operating hours.
After every 200 operating hours.
Use summer filter above 32 F (0 C)
Use winter filter below 32 F (0 C)
1. Disengage the PTO, move the motion control levers to
the neutral locked position and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
Important
Do not substitute automotive oil filter or
severe hydraulic system damage may result.
3. Place drain pan under filter, remove the old filter and
wipe the filter adapter gasket surface clean (Fig. 52).

4. Apply a thin coat hydro fluid to the rubber gasket on
the replacement filter (Fig. 53).
5. Install the replacement hydraulic filter onto the filter
adapter. Do not tighten.
6. Fill the hydraulic tank with hydraulic fluid until the
fluid overflows the filter and then turn the oil filter
clockwise until the rubber gasket contacts the filter
adapter, then tighten the filter an additional 1/2 turn
(Fig. 53).
7. Clean up any spilled fluid.
8. Add fluid to the cold level of the baffle in the
hydraulic tank.
9. Start the engine and let it run for about two minutes to
purge air from the system. Stop the engine and check
for leaks. If one or both wheels will not drive, refer
Bleeding Hydraulic System, page 42.
10. Recheck the fluid level while the fluid is warm. The
fluid should be between cold and hot.
11. If required, add fluid to the hydraulic tank. Do not
overfill.
