Checking the Hydraulic Fluid
Fluid Type: Mobil 1 15W-50 synthetic motor oil or
equivalent synthetic oil.
Important:
Use oil specified or equivalent.
Other fluids could cause system damage.
Hydraulic System Oil Capacity: 67 ounces (2.0 l)
Check the hydraulic fluid level:
•
Before the engine is first started.
•
After the first 8 operating hours.
•
After every 25 operating hours.
Note:
There are two ways of checking the
hydraulic oil. One is when the oil is warm and one
is when the oil is cold. The baffle inside the tank
has two levels depending if the oil is warm or cold.
1. Position the machine on a level surface and set
the parking brake.
2. Clean the area around filler neck of hydraulic
tank (Figure 57).
3. Remove the cap from the filler neck. Look
inside to check if there is fluid in the reservoir
(Figure 57).
4. If there is no fluid, 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
warm the fluid. Refer to Starting and Stopping
the Engine in Operation, page 14.
6. Recheck the fluid level while the fluid is warm.
The fluid should be between cold and hot.
7. If required, add fluid to the hydraulic tank.
Note:
The fluid level should be to the top
of the hot level of the baffle, when the fluid
is hot (Figure 57).
8. Install the cap on filler neck.

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 and Oil
Change the hydraulic filter and oil:
•
After the first 25 operating hours.
•
Change yearly after the first 25 operating hours.
Use summer filter above 32°F (0°C)
Use winter filter below 32°F (0°C)
1. Disengage the PTO, move the motion control
levers to the neutral locked position and set
the parking brake.
