9. Apply slight rearward pressure on the motion
control lever, turn the head of the adjustment bolt
in the appropriate direction until the control lever is
centered in the neutral lock position (Figure 65).
Note:
Keeping rearward pressure on the lever will
keep the pin at the end of the slot and allow the
adjustment bolt to move the lever to the appropriate
position.
10. Tighten the nut and jam nut (Figure 65).
11. Repeat for the opposite side of the machine.

Hydraulic System
Maintenance
Servicing the Hydraulic
System
Checking the Hydraulic Fluid
Service Interval:
After the first 8 hours
Every 25 hours
Fluid Type:
Mobil 1 15W-50 synthetic motor oil or
equivalent synthetic oil.
Hydraulic System Oil Capacity:
132 ounces (3.9 l)
Important:
Use oil specified or equivalent. Other
fluids could cause system damage.
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 66).
3. Remove the cap from the filler neck. Look inside to
check if there is fluid in the reservoir (Figure 66).
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 66).
8. Install cap on filler neck.
