12. Repeat Steps 10 and 11 for the remaining two outrigger
cylinders.
13. Disconnect the return line from the telescope cylinder
and fully extend the boom.
14. Connect the return line and retract the boom. Replenish
the reservoir hydraulic oil level as necessary.
15. Disconnect the return lines from both front steer
cylinders and turn the front wheels to the extreme right.
16. Connect the return lines and turn the front wheels to the
extreme left and then back to center. Replenish the

20. Disconnect one of the lines from the swing motor and
drive the motor in the direction it will go.
21. Connect the line to the swing motor, then drive the swing
motor in the opposite direction until the boom is centered
and forward. Replenish the reservoir hydraulic oil level
as necessary.
When hydraulic oils are changed or added, ensure that
hydraulic oils of different manufacturers are of the same
specifications, however, discoloration (milkiness) may
occur.
When hydraulic oils are changed, recheck the reservoir
hydraulic oil level after brief system operation and add
hydraulic oil as required. Working reservoir capacity
(capacity to full mark) is 656.7 l (173.5 U.S. gal). Ensure the
crane is level and in the travel mode of operation when the
hydraulic system is being filled. The system must be filled
with all cylinders retracted. Fill the reservoir to the full mark
on the reservoir sight gauge. After the reservoir is filled,
operate all circuits and recheck the reservoir sight gauge.
Add hydraulic oil as required.
