Hello, I am experiencing an issue with the Manitou M series 2150. The Right joystick, when first moved, does not generate pressure on the boom for either extending or retracting, as well as for raising or lowering. And this occurs when the unit is first turned on, and sometimes after operating for a while. And if this happens, I have to move the Left joystick first for the Right joystick to function normally. If the Left joystick is not moved, then the Right joystick will remain inactive. And also, during the swing movement or when raising, lowering, extending, and retracting, the unit sometimes becomes jerky. Also, when swinging left, the movement is fast, but swinging right feels very slow. as I continued the work suddenly there was no movement from the hydraulics. This occurred after I swung the unit to the right, and suddenly the unit couldn't move at all accompanied by a red light on the LMI. The display showed that the boom length reached its maximum, while I didn't extend the boom at all. Thank you to the members of this group for providing assistance with this problem.
ROTATION ADJUSTMENT PROCEDURE WITH PLATFORM MOUNTED ROTATION ADJUSTMENT Inside the electronic logic box, which is located behind the cabin, there is the "Danfoss" flow regulator allowing to adapt the rotation speed controlled from the platform (This regulator is mounted in a horizontal position Ref. A-Fig. 12). The adjustment must be made with the thermal engine at 1000 rpm (accelerate the hand lever Ref. B-Fig. 11 to the maximum): ♦ Raise the telescope by about 45° ♦ Extend the telescope for about half of its total travel. ♦ Rotate the turret clockwise using the platform control panel and check that the rotation speed is about 0.7 m/s (if necessary, set "R1"). ♦ Repeat the operation in an anti-clockwise direction and check that the rotation speed is about 0.7 m/s (if necessary, set "R2").
