(1) This machine is an air-operated oilmatic pump which generates 70MPa pressure and operates such
actuator(s) as cylinder(s). As not mounted electric motor, you can enjoy light weight and easy operation.
(2) This pump should be used indoors. Do not use outdoors or the place where pump is to be drenched.
(3) The atmosphere temperature should be between 0 C to 40 C.Z Z
(4) Use RIKEN's genuine peripheral hydraulic power equipment only.
(5) Use RIKEN's genuine high pressure hoses, high pressure pipes and fittings, whose maximum operating
pressure is 70MPa{714kgf/cm }.
2
(6) Do not use this pump at the place where personal injury or property damage might happen when you scatter
the hydraulic working oil through your faults. Do not use this pump around the fire.
(7) This pump is not under the application of the fire laws.

After you change oil, or when the pump sucks air due to lack of oil, air will be mingled into the oil. Then
the pressure will not increase or the cabitations may happen, and the cylinder will not operate smoothly.
Accordingly, release the air as follows.
(A) Open shut-off valve, and operate the pumps.
Shift air shut-off valve to STOP side and to START side by repeating operations 5 to 10 times.
(B) By the above procedures, the air will be released.

If the air is included in the pipings, the cylinder will not operate smoothly. Release the air from the hoses

The air releasing shall be proceeded to release the air outside, but not to retract
the air included oil to the reservoir. Accordingly, the oil in the reservoir will be
decreased. Feed oil as per Page 9. To change hydraulic working oil.

Shift air shut-off valve to START side and STOP side to operate this pump, and close and open
shut-off valve to advance the cylinder piston and retract it respectively.
To use with a single-acting spring-return cylinder
(1) Open shut-off valve.
(2) Shift lever of air shut-off valve to START side to reciprocate the pump piston.
(3) Close shut-off valve.
(4) Cylinder piston advances to increase the pressure and proceed the required job.

(6) When this sound of "pang-pang" occurs, shift air shut-off valve lever to STOP side instantly. The
pump stops operation, and the pressure will be held.
(7) When you retract the cylinder piston, open shut-off valve.
(8) When your job is finished, retract the cylinder piston completely, and stop the air supply.
When unusual conditions or troubles happen, shift air shut-off valve to STOP side instantly, so as!
to stop the pump operation. If you should retract the cylinder piston, open shut-off valve.
Pressure increasing speed shall be controlled by adjusting speed controller.!

8. Repeat open and close of shut-off valve, and check if set pressure is gained or not.
9. Take out the hex. socket head plug of output port, and connect the high pressure hose (or fitting) to oil
output port.
10. Screw Code No. 64 plug.
Do not set this valve at more than 70 MPa {714 kgf/cm }.!

You should set the pressure at more than low pressure than above through the same procedures as!
above. Do not operate high pressure safety valve continuously.
Be sure to wrap tape seals on the hex. socket head plug and hose thread. (See Page 10. How to Wrap!

Check the hoses visually at daily use or once a week. If the following abnormal conditions exist, stop the
operation at once, and change hoses or take a particular counter measures.
If the oil leaks from the taper thread parts, take out the hose, then use 1 to 2 wraps of tape seals, and!
tighten again by the required torque. If oil still leaks, change hoses.
If there are oil leakage from the thread parts or outer surface of the hose, or the outer surface is uneven!
or cracked, change the hose with new one.
