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
Hot hydraulic fluid can cause severe burns.
Allow the hydraulic fluid to cool before
performing any maintenance to the
hydraulic system.
Change the hydraulic filter as follows:
•
After the first 8 operating hours.
•
After every 200 operating hours or yearly
before storage.
1. Disengage the PTO and set the parking brake.
2. Stop the engine 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. Remove hydraulic reservoir cap and
temporarily cover opening with a plastic bag
and rubber band to prevent all hydro fluid
from draining out.
4. Locate the filter under the fuel tank and place
drain pan under filter (Figure 65).
Figure 65
5. Remove the old filter and wipe the filter
adapter gasket surface clean (Figure 66).
6. Apply a thin coat hydro fluid to the rubber
gasket on the replacement filter.
7. Install replacement hydraulic filter onto the
filter adapter. Do not tighten.
8. Remove plastic bag from reservoir opening
and allow filter to fill with hydraulic fluid.
9. When the hydraulic filter is full, turn the oil
filter clockwise until the rubber gasket contacts
the filter adapter, then tighten the filter an
additional 1/2 turn (Figure 66).

10. Clean up any spilled fluid.
11. Check the fluid in the reservoir, add fluid to the
tank until it reaches the cold baffle of the tank.
