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.
Warning
Replacing the Hydraulic Filter
Change the hydraulic filter:
•
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 power take off (PTO) and stop the
engine. Move the levers to the neutral locked position
and apply the parking brake. Remove the key.
Important
Do not substitute an automotive oil filter or
severe hydraulic system damage may result.
2. Tilt the seat forward to access the filter.
3. Remove the hydraulic reservoir cap and temporarily
cover the opening with a plastic bag and rubber band to
prevent all hydro fluid from draining out.
4. Place a drain pan under the filter, remove the old filter,
and wipe the filter adapter gasket surface clean
(Fig. 52).

5. Apply a thin coat of hydro fluid to the rubber gasket on
the replacement filter (Fig. 53).
6. Install the replacement hydraulic filter onto the filter
adapter. Do not tighten.
7. Remove the plastic bag from the tank opening and
allow the filter to fill with hydro fluid.
8. When the fluid overflows the filter, turn the oil filter
clockwise until the rubber gasket contacts the filter
adapter; then tighten the filter an additional 1/2 turn
(Fig. 53).
9. Clean up any spilled fluid.
10. If there is no fluid, add fluid to the reservoir to
approximately 1/4 inch (6 mm) below the top of the
baffle.
11. 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 to
Bleeding the Hydraulic System, page 39.
12. Check the fluid level in the hydraulic tank while the
fluid is warm. Add fluid to raise the level to the top of
the baffle, if required. Do not overfill.
