4. If the fluid is low, add fluid to the reservoir until it
reaches the cold level of the baffle.
5. Run the machine at low idle for 15 minutes to allow
any air to purge out of the system and heats the fluid.
Refer to Starting and Stopping the Engine on page 20.
6. Recheck the fluid level while the fluid is hot. If
required, add fluid to the reservoir until it reaches the
hot level of the baffle.
Note: The fluid level should be to the top of the hot level
of the baffle, when the fluid is hot (Fig. 44).
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
Warning
Hot hydraulic fluid can cause severe burns.
Allow the hydraulic oil to cool before
performing any maintenance to the hydraulic
system.
Change the hydraulic filter:
After the first 200 operating hours.
Yearly, before storage.
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. 45).

4. Apply a thin coat hydro fluid to the rubber gasket on
the replacement filter (Fig. 46).
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. 46).
