When I active my automatics the blade jumps up and down several inches. The blade doesn’t stay at the same elevation consistently. Is this normal? What can I do to fix this?
There is a possibility that the Work Equipment Handle (joystick) has some excessive play in it. If you notice play in it, it can cause the blade to be jerky or act erratically. There is a service bulletin for this through Komatsu. It could also be a bad design. You could create a flat pad and see if it works any better on a level surface. If the machine used to work fine I would lean towards one of the prior things I've mentioned. If not, it could be a variety of calibration issues or stroke sensor issues. If you don't have a Komatsu TSE to talk to let me know where you are located and I can probably get you in touch with someone near you.
