I picked up (actually I was paid to haul it off) a 2007 337g. It appears to have almost 0 hydraulic power. Have to max engine RPM to raise the main stick. Machine is not strong enough to lift itself up. Engine does not bog, all hydraulics function but do not have any strength. This is the first excavator I have ever touched. Any ideas as to the source of the problem?
Good day T-ranch Suggest you check out that the lowering the left consul is activating the controls and then move on checking the pressures. kind regards Uffex
