Working with the machine
Note! Turning on the float position of the boom cylinders can, depending on the kind of the material, facilitate the penetration of the shovel in the heap to be hollowed. When leveling out the working area, the bucket follows automatically the solid ground contour during the stick extension ( movement "b" controlled by the left joystick 3), and the shoveling up of the loosen material is made easier.
Control of the bucket or grapple cylinders The bucket cylinder as well the grapple cylinders are controlled by the right joystick 3.

Operation of the bucket or grapple cylinders
Push the joystick 3 to the left e. The bucket is tilted in, or the grapple closes. Push the joystick 3 to the right f. The bucket is tilted out, or the grapple opens. Danger Never allow anybody to guide the grapple by hand!
Combined movements A diagonal movement of the joystick combines the corresponding movements of the working attachment. This makes it possible for all attachment movements to be actuated at the same time.

Lowering the working attachment with the engine shut down In an emergency, the attachment can be lowered also when the engine is not running. Note The attachment can be lowered thanks to a pressure accumulator mounted to the control oil unit. Due to the small volume of this accumulator only a limited number of movements can be actuated by the pilot control devices. Only operate the joysticks in the directions for lowering the attachment. Only the movements resulting from the own weight of the attachment parts are possible.
