When removing parts at locations where there are O-rings or gasket seals, clean the mounting surface, and replace with new parts. When doing this, be careful not to forget to assemble the O-rings and gaskets. When installing the hoses, do not twist them or bend them into loops with a small radius. This will cause damage to the hose and markedly reduce its service life. Checks After Inspection and Maintenance Works 0.
