(4) Caution Make sure that plumbing and wiring are correct and all the connection is tightened correctly before you start operating, especially if it is the first run. (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. (5) (6) (7) Caution Caution Caution (4) Cautions related to maintenance and storage () (2) (3) (4) Caution Caution Caution Caution Use the product under the specification mentioned in the catalog, drawings and specification sheet. Keep your hands and body off the product during the operation as it may become hot due to oil temperature and temperature increase of the solenoid. Otherwise you may suffer burns. Use the proper hydraulic oil, and maintain the contamination in the recommended level. Otherwise the product may not work or be damaged. Never modify the product without approval of Kawasaki. Do not disassemble and reassemble the product without approval of Kawasaki. It may cause troubles and failures, or it may not work as specified. If it is necessary by all means to disassemble and reassemble it, it must be done by an authorized person. Keep the product from dust and rust by paying attention to the surrounding temperature and humidity when you transport or store the product. Replacing the seals may be required if you use the product after long time storage. 3
