I went out to a job on a 345 excavator, complaint is boom dropping.
When operating the machine, boom will lift ok then sometimes as it is being lifted it will drop to the ground very fast while control is still in lift position.
When using the controls very slow it it worked for a short while, boom did not drop. As soon as I tried normal speed boom would drop.
After I released the pressure in the hyd. tank and checked the oil level (no oil added) every thing worked ok for rest of the day. the problem is intermittant some days ok.
Any help would be good
