Servicing the Hydraulic
System
Checking the Hydraulic Fluid
Check the hydraulic fluid level before engine is first
started.
Check the hydraulic fluid level after first 8 operating
hours.
Check the hydraulic fluid level after every 40 operating
hours.
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 liter)
Note: The hydraulic oil can be checked when the oil is hot
or cold. The baffle inside the tank has two levels
indicating the oil level when it is hot or cold.
1. Position machine on a level surface and set the parking
brake.
2. Clean area around filler neck of hydraulic tank
(Fig. 50).
3. Remove cap from filler neck. Look inside to check if
there is fluid in the reservoir. (Fig. 50).
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 23.

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. 50).
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.
