1.Check each part of fasteners, ensure they are fixed.

2.Make sure that all connectors of the hydraulic pump station are equipped with oil seal rings, if the seal rings appear damaged or oil leakage, should be replace timely.

3.If found forward or backward abnormality, first check electro-hydraulic valve whether operate normal, if working normally, then you should check whether the electro-hydraulic relief valve or the one-way unloading valve has contaminant that made it could not working or not(this phenomenon usually happen when you just use this machine).
