Charging the Hydraulic System

Hydraulic System: Service and Repairs
Air must be purged from the system to reduce the chance of
component damage.
When initially starting the hydraulic system with new or rebuilt components such
as motors or pumps, it is important that the hydraulic system is charged properly
to remove air from the system.
Note: Flush the hydraulic system whenever there is a severe component failure
or the system is contaminated; refer to
5–38).
1. Park the machine on a clean, level surface with the engine off. Lower and
lock the transport wheels (drive roller off ground).
2. Ensure that all of the hydraulic connections, lines, and components are
secured tightly.
3. Ensure that the hydraulic tank is full. Add the correct quantity and type of
hydraulic fluid if necessary; refer to the Operator's Manual.
4. Check the motion control linkage for proper adjustment, binding, or damaged
parts.
5. Prime the hydraulic pump; refer to
6. Start the engine and run it at low-idle speed.

the engine and determine the cause.
7. After the hydraulic system starts to show signs of filling, press the motion
control pedals to rotate the drive roller right and left several times.
8. Ensure that the motion control pedals return to the N
released and adjust if necessary.
9. Operate the motion control pedals in the left and right directions. Make sure
the drive roller is turning in the proper direction and allow the drive roller
to turn slowly for ten (10) minutes.
10. Shut off the engine.
11. Operate the machine by gradually increasing its work load to full over a 10
minute period.
12. Stop the machine, check the hydraulic components for leaks and tighten
any loose connections.
13. Check the hydraulic fluid level in the hydraulic tank and adjust as necessary;
refer to the Operator's Manual.
Note: If new fluid shows any signs of contamination, flush hydraulic system
again until the fluid is clean; refer to
