Charging the Hydraulic System
IMPORTANT
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, pumps, or cylinders, it is important that the hydraulic system
is charged properly to remove air from the system.
IMPORTANT
Flush the hydraulic system whenever there is a severe component
failure or the system is contaminated; refer to
.
1. Park the machine on a level surface and turn the engine OFF.
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 traction unit
Operator’s Manual
.
4. Check the traction control components for proper adjustment, binding, or
damaged parts.
5. Prime the hydraulic pumps; refer to
Priming the Hydraulic Pumps (page
.
WARNING
Review and follow
Jacking Instructions (page 1–8)
before jacking
up the machine.
6. Raise the wheels off the floor and support the machine with jack stands.
IMPORTANT
Check hydraulic tank fluid level frequently while charging the system
and add fluid as necessary.
7. Start the engine and let it idle at low speed.
Note:
The hydraulic pumps should pick up hydraulic fluid and fill the hydraulic
system. If there is no indication of the system filling within 30 seconds, stop
the engine and determine the cause.
8. After the hydraulic system starts to show signs of filling, operate the hitch lift
cylinders up and down the full distance several times. If the cylinders do not
move after 15 seconds or the pump emits abnormal sounds:
A. Turn the engine OFF immediately
B. Make sure one of the hydraulic fluid filters or the suction line is not loose
C. Check for incorrect hose routing
D. Ensure the suction line is not blocked
