Hot hydraulic fluid can cause severe burns.
Allow the hydraulic oil to cool before performing
any maintenance to the hydraulic system.
1. Replace the hydraulic oil filter; refer to Replacing the
Hydraulic Oil Filter.
2. Clean the area around one hydraulic hose fitting on
the bottom of the hydraulic oil tank (Figure 60).

1. Hydraulic hose and fitting
3. Place a large pan under the fitting.
4. Remove the hose fitting from the tank, allowing the
oil to drain into the pan (Figure 60).
5. Install the hose and fitting to the tank and tighten
it securely.
6. Fill the hydraulic reservoir with approximately 10.6
US gallons (40.1 l) of Mobil DTE 15M hydraulic oil
or equivalent.
7. Start the machine and run it at idle for 3 to 5 minutes
to circulate the fluid and remove any air trapped in
the system.
8. Stop the engine, check the hydraulic oil level, and
check for leaks.
9. Dispose of the used oil at a certified recycling center.
Checking the Hydraulic Lines and
Hoses
Inspect the hydraulic lines and hoses daily for leaks,
kinked lines, loose mounting supports, wear, loose
fittings, weather deterioration and chemical deterioration.
Make all necessary repairs before operating.
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Ensure that all hydraulic fluid hoses and
lines are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to the hydraulic system.
• Keep your 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.
• Get immediate medical help if fluid is
injected into skin.
