Hydraulic System Oil Capacity: 132 ounces (3.9 l)

Checking the Hydraulic Fluid Level
Service Interval: After the first 8 hours
Every 25 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 75).
3. Remove the cap from the filler neck. Look inside to
check if there is fluid in the reservoir (Figure 75).
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 (page 20).
Recheck the fluid level while the fluid is warm. The
fluid should be between cold and hot.
6. 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 75).
7. Install cap on filler neck.
