I replaced some of the hoses on my M1084A0 Material Handling Crane. Lost about 2.5 gallons of hydraulic fluid during the hose replacement process. I was impatient and tested the system without refilling the reservoir. All systems worked fine until the boom extension and lift cylinders seem to stall. The other crane control components seem to be working well.
Attempted to search prior threads for this scenario without success. Given my feeble knowledge of hydraulic systems, I did not find any remedies in the tech manuals either.
Do these cylinders have pilot control valves at the cylinder base? Is it possible the pilot has lost prime due to the low fluids from replacing the hoses? If so, what is the best way to re-prime?
Stay safe and stay in touch,
