System
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: 132 ounces (3.9 1)
Check the hydraulic fuid level:
• Before the engine is first started.
• After the first 8 operating hours.
• After every 25 operating hours.
Note: There are two ways of chec_ng 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 paring brake.

Clean the area around filler neck of hydraulic
tank (Figure 65).
Remove the cap from the filler neck. Look
inside to check if there is fluid in the reservoir
(Figure 65).
If there is no fluid, add fluid to the reservoir
until it reaches the cold level of the baffle.
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 15.
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 65).
8. Install cap on filler neck.
