hello everyone. bought a old daewoo 220-3 machine with the kawasaki kv pump engine is running great but seems to have a weak set of pumps or out of adjustment how do i adjust these kv pumps? they look identical to the old hitachi kv pumps machine seems to have low pressure on one pump maybe both.. doesn't track straight... right track is weak but left seems strong. it also seems to take forever to complete a cycle
Good day I believe you need a flow- pressure measuring device to adjust the pump's however pressure control is on the valve chest. Kind regards Uffex
