When the cab safety operator arm rail is lowered, there is now a large clack sound from the rear or engine compartment area and the engine labors hard (will in fact stall if idling). Drive motion is not affected but all arm functions, raise, tilt are. The arm or tilt functions will operate for a second or two then movement stops, the engine stops laboring but arm functions no longer operate - until the operator safety armrest is raised and lowered. I thought I read a post discussing hydraulic bleed procedures and was looking for some info on that or any pointers to what to check. Because it seems to shut down the hydraulics and stops laboring I also wonder if there is a solenoid or pressure relief valve involved. Hydraulics have been working fine up to this point and I dont think the level was that low (do not have any hydraulic leaks and did not have to add maybe 1 or 2 qts). thanks</p></blockquote><p></p>
