We purchased a 621 liebherr in good to great condition ran it a day or two and now the bucket will not raise. Replaced the float tilt button on top of right control lever no change. If you turn the power key off the bucket will raise until you engage the saftey switch to move the loader than its back to nothing again. All other movements work tilt forward and back and down along with the float button and auto tilt when in gauged. Were thinking a fuse or solenoid somewhere causing this problem.......please any help would be great spent a pile of money to by this and fuunds are low to take to a shop for the to fix.
I also have two bucket cylinders I just took off our 941b one has the auto level on...both in great shape if anyone is looking for a pair
