Hello people, Recently i bought an old komatsu pc15-2 excavator. All functions works but when i use the boom up and curl the bucket at the same time. the boom dos not go up until the bucket is on the end of its stroke and then the boom goes up. Does anybody know what this problem would be? I added the hydraulic diagram with this post. Greetings from the Netherlands Patrick Kuiken
That is normal; The problem is not with your device. Mini excavators are usually like that. If you want to boom up at the same time as curl buckets, you must release the bucket control lever a little. This requires your excavator operating skills to be good
