6. Lift and support the machine with jack stands so that all the drive wheels
are off the ground.
Ensure that the machine is safely supported so that it does not move
or accidentally fall and prevent injuring anyone under the machine.
7. Ensure that the traction pedal is in the N
and run it at low-idle speed (1,400 rpm).
Note: The piston and gear pumps must pick up the hydraulic fluid and fill the
hydraulic system. If there is no indication of fill in 30 seconds, shut off the
engine and find the cause.
8. After the hydraulic system starts to show the signs of fill, actuate a deck lift
switch until the lift cylinder rod moves in and out several times.
9. If the lift cylinder does not move after 3 to 5 seconds or if the pump emits
abnormal sounds, shut off the engine immediately, and find the cause or
problem. Inspect for the following:
A. The oil filter or suction lines that are loose.
B. An incorrect hose routing.
C. The suction line that is blocked.
D. The implement relief valve that is damaged.
E. The gear pump that is damaged.
10. After the lift cylinder moves normally, proceed to step 11.
11. Turn the steering wheel in both directions so that the steering cylinders move
in and out several times.
12. Operate the traction pedal in the forward and reverse directions. The drive
wheels should rotate in the proper direction. If the wheels rotate in the wrong
direction, shut off the engine, inspect the wheel motor location and hydraulic
lines to the wheel motors; refer to
13. Adjust the traction pedal to the N
Manual.
14. Lower the machine to the ground.
15. If the transmission or a wheel motor was replaced or rebuilt, operate the
traction circuit on a level ground so that all the drive wheels rotate slowly
for 10 minutes.
16. Operate the machine by gradually increasing its work load to full over a 10
minute period.
Note: Some aeration of hydraulic fluid on this machine is normal. This
aeration (foaming) may be more noticeable after initial filling of the hydraulic
tank.
17. Stop the machine. Check the hydraulic-fluid level in the hydraulic reservoir
and add correct quantity of fluid if necessary; refer to the Operator's Manual.
18. Check the hydraulic components for leaks and tighten any loose connections.
