2 The following must be taken into consideration in actual PRECAUTIONSB efore you use the product, you MUST read the operation or operators manual and MUST fully understand how to use the use the product safely, you MUST carefully read all Warnings and Cautions in this manual. You MUST also observe the related regulations and rules regarding safety. Installation, removal, plumbing, and wiring must be done by the certified person.*CERTIFIED PERSON: a person who has enough knowledge like a person who is trained by Kawasaki s hydraulic school. Make it 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 the system pressure has dropped to off the power before starting wiring or other works related to the electric power, otherwise you may be stuck by an electric the specified bolts and keep the specified tightening torque when you install the product.

3 Usage of unauthorized bolts, lack of torque or excess of torque may create problems such as failure of work, damage and oil leakage. Clean the threads and mounting surface completely, otherwise you may experience damages or oil leakage caused by insufficient tightening torque or broken seal. WARNINGCAUTIONCAUTIONUse the product under the specification mentioned in the catalog, drawings and specification your body off the product during the operations as it may become hot and burn your body. Use the proper hydraulic oil, and maintain the contamination in the recommended level, otherwise it may not work or be damaged. CAUTIONCAUTIONCAUTIONUse the safety equipment to avoid the injury when you operate the enough attention on handling method to avoid pinching hands or back problems that may be caused by heavy weight of the product or handling not step on the product, hit it, drop it or give strong outside force to it, as one of these actions may cause the failure of work, damage or oil the oil on the product or floor off completely, as the oil creates slippery conditions that may result in dropping the product or related to operationNever use the product not equipped with anti-explosion protection in the circumstances of possible explosion or combustion.

4 Shield the rotating part such as motor shaft and pump shaft to avoid injuries caused by being caught of fingers or cloths. Stop the operation immediately if you find something wrong such as unusual noise, oil leakage or smoke, and fix it properly. If you continue operating, you may encounter damage, fire or injury. Make it 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. DANGERWARNINGWARNINGCAUTIONW arnings and Cautions for operationWarnings and Cautions related to installation and removal of the productNever modify the product without approval of Kawasaki. Do not disassemble and assemble without approval by Kawasaki. It may cause troubles and failure, or it may not work as specified. If it is necessary by all means to disassemble and assemble, it must be done by an authorized the product from dust and rust by paying attention to the surrounding temperature and humidity when you transport or store the product.

Long LifeA long life is obtained by adopting main bearings of large capacity and the Piston -return mechanism that compensates for the wear of the Low NoiseEven less noise has been achieved because of the op-timum design of the valve plate and the casing Wide Range of ControlsThe pump can be controlled in various kinds of control methods and is capable of responding to either mech-anical, hydraulic or electrical High Power DensityA lighter and more compact machine with higher pres-sure rating and increased power density (output pow-er/mass)
