4.2 Before hydraulic cylinder is assemblied , every spare parts
would be measured and cleaned .After hydraulic cylinder is
assemblied , pressure test would be carried out one by one.We
ensure the testing pressure is 30%-50% higher than rated pressure
in almost one hour's test.Each hydraulic cylinder must be tested
without any leakage.
