18. Push all four outrigger levers fully forward and run engine until the outriggers all touch
the ground. Stop the engine.
19. Release the outrigger levers and pull the SWING lever fully. Run the engine for 3
seconds and stop engine.
20. Release SWING lever and pull SLOW HOIST lever to full raise position and run
engine for 7 seconds, then stop engine.
21. Fill hydraulic reservoir.
22. Release hoist lever and push SLOW CROWD lever fully forward in the extend
position. Run the engine until the boom extends fully, then stop engine.
23. Reconnect the return hoses. Be sure all shutoff valves are open.
24. Retract the boom and fill the reservoir.
25. Run engine and cycle all of the cylinders in and out several times.
REMOVAL OF AIR FROM HYDRAULIC CIRCUITS
If air has been introduced into the hydraulic oil or trapped in a hydraulic cylinder,
performance of the machine may suffer. The source of the air should be found and fixed.
Purge remaining air from hydraulic circuits as follows:
To remove air from hydraulic circuits, perform the following steps:
1. Ensure all main shutoff valves on the reservoir are open.
2. Start the engine.
3. Raise and lower the boom minimum five times. Ensure that the cylinder travels full
stroke.
4. With the boom retracted and elevated to at least 65°, raise and lower the hook at
least once.
5. Extend and retract the boom minimum five times.
6. Swing the turret left one full revolution. Swing the turret right one full revolution.
7. Raise and lower each outrigger minimum five times. Outriggers can be operated in
pairs.
8. With the crane on outriggers, steer the crane wheels fully left and right three times
in each steering mode.
9. With the crane on outriggers, bleed the fluid lines to the brake calipers.
10. BMC uses multiple types of RCL computer. If the RCL computer is connected to
the topping cylinder by hose, it may be necessary to bleed this hose. Perform the
following:
a. Raise the boom to approximately 5°.
b. Turn off engine.
W A R N I N G
The boom will lower during this procedure. Failure to keep the boom free of
obstructions could lead to destruction of property, injury, or death.
