I. Applications / Product Usage

The following must be taken into consideration before use.

1. The operating condition of the products

shown in this catalog varies depending upon

each application. Therefore, the suitability

of the products use must be made by the

designer of the hydraulic system and/or the

person in charge of determining the machine's

specification after analysis and testing.

The product specification shall be determined

based on the latest catalog and technical

documents. 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 SAFETY

PRECAUTIONS 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) Atomic power, aviation, medical treatment,

and/or food production

(3) Use likely to affect human beings or assets

the product. To use the product safely, you MUST carefully read all Warnings and Cautions in

this catalog.

1. Cautions related to operation

2. Warnings and Cautions related to installation and removal of the product

3. Warnings and Cautions for operation

4. Cautions related to maintenance

- 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.

- 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.

- Always 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.

- 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.

III. 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

To minimize both oil and seal deterioration a

maximum operating temperature of 140ºF (60ºC)

should be considered.

Additionally it must be noted that when operating at

low temperatures 59-68ºF (15~20ºC) some delay in

response of the regulator may occur.

At such low temperatures it is strongly suggested

that a warm up cycle is introduced until an operating

temperature of 68ºF (20ºC) is achieved.

2. CleanlinessFor satisfactory service life, cleanliness level should

meet ISO4406 -/18/15 (NAS1638 Class9).

3. Connection of drive shaft

1) Install the motor horizontally to the shaft direction.

2) Alignment should be within specifications below.

Parallel misalignment 0.05mm

(Dial gauge reading a = below 0.10mm)

Angular misalignment 0.2deg

4. Oil filling and Air 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) Air 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) After long interval of operation

After 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.

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.

2) Size of the drain hose or pipe

The internal bore size must be larger in size than the

drain port. Arrange the piping as short as possible.

3) Casing pressure

Permissible maximum case pressure is 29psi (2bar)

normally and 87psi (6bar) peak. Refer to the following

figure measured at the drain port of the motor.

4) Influence of casing pressure on beginning of control

An increase in casing pressure affects the beginning of

control of the variable motor when using the following

control options ; T3 and P3 increase.

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.

2-2 Precautions for System Design

• Minimum Boost Pressure

To prevent cavitation when the motor is operating

in a pumping mode, a positive pressure is required

at the inlet port.

The figure on the right shows the minimum boost

pressure requirement based on regular operation.

In case of a rapid change of the flow, more boost

pressure must be applied.

2-2 Precautions for System Design

M7V series

• Minimum Boost Pressure

To prevent cavitation when the motor is operating in

a pumping mode, a positive pressure is required at the

suction port.

The figure on the right shows the minimum boost

pressure requirement based on the regular operation.

In case of a rapid change of the flow volume, more

boost pressure must be applied.

• Minimum Back Pressure

To ensure the optimal performance and life time the

back pressure is required at the lower pressure port.

Motor casing pressure must be 29psi (2bar).

• Permissible displacement, speed relatedThe figure on the right shows permissible

displacement in relation to the motor operating speed.

Design the system not to exceed this requirement.

• Beginning of control for winch deviseFor the safety reasons, winch motors are not

permissible with beginning control at qmin.

2-3 Displacement Adjuster

• Displacement Adjuster

Maximum displacement and minimum displacement can be adjusted by the displacement adjuster.

Adjustable range of maximum and minimum displacement is shown in the table below.

Adjustable Range of max. displacement

Adjustable Range of min. displacement

Note.

1. By adjusting the qmax. adjuster the minimum displacement is changed because of structure of the displacement adjuster. Please adjust the minimum displacement after the maximum displacement is adjusted.

2. The minimum displacement is determined by the total length of the adjuster (Lmax)

This control type is for code T1 and T2.

• Function

Displacement is changed from maximum to minimum

by energizing the solenoid.

Control pressure is internally supplied by the port

with the highest pressure.
