(2) recautions in installing and removing the product () (2) (3) (4) (5) Caution Warning Warning Caution Caution Installation, removal, plumbing and wiring must be done by the certified person. *CERIFIED ERSON: person who has enough knowledge like a person who is trained by Kawasaki's hydraulic school. Make sure that the power of the hydraulic power unit is turned off and that the electric motor or engine has completely stopped before starting installation or removal. You must also check that the system pressure has dropped to zero. e sure to turn off the power before starting wiring or other works related to the electric power. Otherwise, you may receive an electric shock. Clean the mounting holes and mounting surface completely. Otherwise you may experience damages or oil leakage caused by insufficient tightening torque or broken seal. e sure to use the specified bolts and keep the specified tightening torque when you install the product. Usage of unauthorized bolts, lack of torque or excess of torque may create problems such as failure of work, damage and oil leakage.
