The system must be designed taking into account the possibility of machine failure, and insuring that all safety, warning, and application requirements are met. 2. For the proper use of the products, descriptions given in the SFETY PRECUTIONS must be observed. 3. The technical information in this catalog represents typical characteristics and performance of the products as of the published date. 4. If the products are used in the following conditions or environments, please consult Kawasaki prior to implementation. (1) Unspecified conditions or environments (2) tomic power, aviation, medical treatment, and/or food production (3) Use likely to affect human beings or assets significantly or requiring particular safety. 5. The information described in this catalog is subject to change without notice. For updated information, please consult Kawasaki. 2

3 . Safety Precautions Before using the product, you MUST read this catalog and MUST fully understand how to use the product. To use the product safely, you MUST carefully read all Warnings and Cautions in this catalog. 1. Cautions related to operation - Use safety equipment to avoid the injury when you operate the product. - Pay close attention while handling the product to avoid injury that may be caused by the heavy weight of the product or improper handling posture. - Do not step on, hit, drop or give strong outside force to the product, as one of these actions may cause failure of operation, damage, or oil leakage. - Wipe off any oil on the product or floor completely, as the oil creates slippery conditions that may result in dropping the product or personal injury. 2. Warnings and Cautions related to installation and removal of the product - Installation, removal, plumbing, and wiring must be done by a qualified technician. - Make sure that 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. - Turn off the power before wiring or performing other duties related to the electric power to avoid risk of electric shock. - Clean the threads and mounting surface completely to prevent damage or oil leakage caused by insufficient tightening torque or broken seal. - Use the specified bolts and maintain the specified tightening torque when you install the product. Usage of unauthorized bolts, lack of torque or excess torque may create problems such as failure of operation, damage, and oil leakage. 3. Warnings and Cautions for operation - lways equip the product with anti-explosion protection in the circumstances of possible explosion or combustion. - Shield rotating parts, such as the motor and pump shaft, to avoid injuries. - Stop operation immediately if you find unusual noise, oil leakage or smoke, and fix properly. Continuing operation may cause damage, fire or injury. - Make sure that plumbing and wiring are correctly connected and tightened before operation. - Use the product according to the specifications provided in the catalog, drawings and specification sheets. - The product may become hot during operation. - Use the proper hydraulic oil and maintain the filtration at the recommended level to prevent premature wear and damage. 4. Cautions related to maintenance - Never modify the product without approval from Kawasaki. - Disassembly of the product may void the warranty. - Keep the product clean and dry when storing or transporting. - The seals may need to be replaced if the product has been stored for an extended period of time. 3

4 M7X / M7V MOTORS. Handling Precautions 1. Operating fluid and Temperature range 1) Operating fluid Values shown in this catalog are based upon using mineral oil based anti-wear hydraulic fluid. If using special fluid (phosphate ester, water-glycol, fatly acid ester, etc), please consult Kawasaki for instructions prior to use. 2) Viscosity and Temperature range 3. Connection of driving shaft 1) Install the motor horizontally to the shaft direction. 2) lignment should be within specifications below. Parallel misalignment 0.05mm (Dial gauge reading a = below 0.10mm) ngular misalignment 0.2deg dial gauge (reading a) dial gauge (reading b) a/2 SIN -1 (b/d) To minimize both oil and seal deterioration a maximum operating temperature of 60 should be considered. dditionally it must be noted that when operating at low temperatures in winter (1520 ) some delay in response of the regulator may occur. t such low temperatures it is strongly suggested that a warm up cycle is introduced until an operating temperature of 20 is achieved. datums datums D b Viscosity [mm 2 /s(cst)] Fluid Temperature [C (F)] kinematic viscosity (cst) Recommend Suitable range for Normal operation llowable range (4194) allowable temperature range fluid temperature () Suitable range for Normal operation 4. Oil filling and ir venting 1) Oil filling Be sure to fill the casing with oil through the drain port before start up. Operation of the motor with an insufficient amount of oil may cause seizure of parts such as bearings and pistons. 2) ir venting Vent the air out of the motor and hydraulic circuit prior to operation. The air left in the circuit may cause damage or reduction of motor performance. 3) fter long interval of operation fter long interval of operation the operating fluid may have drained away from the motor. Be sure to fill the casing with oil before restart of the system. Volume of the oil is shown in the "Specifications" table. 2. Cleanliness For satisfactory service life, cleanliness level should meet ISO4406 -/18/15 (NS1638 Class9). 4

5 . Handling Precautions 5. Drain piping 1) Location of the drain piping Drain port at the highest position of the motor should be used. Drain piping must be arranged as shown in the following figure so that the motor case is filled with the oil. The drain piping must be connected directly to the tank. 6. Thrust and Radial load to the shaft 1) Thrust load Do not apply any form of thrust load to the shaft end. 2) Radial load Radial load is acceptable under certain conditions. Please contact Kawasaki if a radial load is applied to the shaft. Bearing life will be reduced depending on the load, direction and location of the load on the shaft. 2) Size of the drain hose or pipe The internal bore size must be larger in size than the drain port. rrange the piping as short as possible. 3) Casing pressure Permissible maximum case pressure is 0.2 MPa normally and 0.6 MPa peak. Refer to the following figure measured at the drain port of the motor. P 0.1sec 0.6MPa87psi peak 0.2MPa29psi normal 4) Influence of casing pressure on beginning of control n increase in casing pressure affects the beginning of control of the variable motor when using the following control options ; T3 and P3 increase. Control option T3 P3 Beginning of control Increase 5
