3. Remove cap from filler neck. Look inside to check if
there is fluid in the reservoir (Fig. 81).
4. If there is no fluid, add fluid to reservoir approximately
a 6mm (1/4 in.) below the top of baffle.
5. Run the machine 15 minutes to allow any air to purge
out of the system and warm fluid.
6. Recheck level while fluid is warm. Add fluid to raise
level to top of the baffle, if required.
Note: Fluid level should be to the top of the baffle when
fluid is warm (Fig. 81).
7. 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:
After the first 8 operating hours
After every 200 operating hours
1. Position machine on a level surface, stop the engine,
and remove key from ignition switch.
Important
Do not substitute automotive oil filter or
severe hydraulic system damage may result.
2. Remove hydro cap and temporarily cover opening with
a plastic bag and rubber band to prevent all hydro fluid
from draining out.
3. Place drain pan under filter, remove the old filter and
wipe the filter adapter gasket surface clean (Fig. 82).

4. Apply a thin coat hydro fluid to the rubber gasket on the
replacement filter (Fig. 83).
5. Install replacement hydraulic filter onto the filter
adapter. Do not tighten.
6. Remove plastic bag from tank opening and allow filter
to fill with hydro fluid.
7. When fluid overflows filter turn the oil filter clockwise
until the rubber gasket contacts the filter adapter, then
tighten the filter an additional 1/2 turn (Fig. 83).
8. Clean up any spilled fluid.
9. If there is no fluid, add fluid to reservoir approximately
a 6mm (1/4 in.) below the top of baffle.
10. Start engine and let 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 44.
