1.1 Names of Parts
1.2 Contents of Package
The main equipment and accessories are packed in different cases. Open the top part of the corrugated fiberboard
case and check if the pump assembly and oil tank are not damaged and if accessories are all contained in the
package.
2. Principles of Operation
The Yamada Air-powered Pump is a reciprocating type that is
driven by compressed air. The pump consists of an air motor to
drive the pump and a lower pump to draw up the material as shown
in the figure at right.
When compressed air is supplied from the compressor to the air
motor, the air piston starts its up/down motion by the function of the
air switching mechanism built in it.
This motion is transmitted to the piston of the lower pump by the
connecting rod that connects between the air piston of the air motor
and the piston of the lower pump, thereby giving the up/down
motion to it.
When the up/down reciprocating motion of the piston of the lower
pump is performed, the material is sucked into the lower pump and
fed out from the discharge port by pressure.

3. Preparations before Operation
3.1 Setting the Hose
1) Install the attached oil-proof hose and the grip meter at the oil discharge
port of the pump, and clamp the connecting portion securely.
2) Connect the attached air chuck to the air hose and fix it with a hose band.
(The air hose is separately available.) If the air chuck to be connected to
the compressor is not available, purchase it separately. (Fig. 1)
3.2 Setting Oil
1) Release the 3 clasps on the top of the oil tank, and the lid can be removed
together with the pump Assy.
2) Supply new oil in the oil tank. (Fig. 2)
<NOTE>
Take extreme care not to allow sand and dust to adhere on the suction
tube and float of the pump.
3) Put the lid on the oil tank as it was and fix the oil tank and the lid with the 3
clasps.
3.3 Operating the equipment
1) Turn the knob of the air regulator counterclockwise to reset the indicator of the pressure gauge to “0”. After that,
connect the air chuck to supply air.
<NOTE>
Using an air regulator permits adjusting the supply air pressure to the pump and reducing unnecessary pump
motion, thereby improving the work efficiency and extending the life of the pump.
When the knob of the air regulator is turned clockwise, the air pressure will be increased (the indicator of the
pressure gauge gradually goes from “0” to a larger number). When the knob is turned counterclockwise, the air
pressure will be reduced (the indicator of the pressure gauge goes back to “0”).
2) As the knob of the air regulator is gradually turned clockwise, the will be started when the supply pressure is 0.2 or
0.3 MPa.
3) The pump is operated for a while and then stops when the hose is filled with oil. If the gun lever is pulled in this
status, the oil lubricator can be used any time.
4) Set the supply air pressure to 0.5 to 0.7 MPa.

4. How to Operate the Machine
WARNING
- When the machine is operated, electrostatic sparks may give a shock to the human body or cause
death or bodily injury due to a fire or explosion. Be sure to perform grounding securely by using a
grounding conductor according to the operating environment.
CAUTION
- The supply air pressure should be 0.7 MPa or less. If the primary pressure is more than 0.7 MPa,
install an air regulator on the air line and adjust the pressure to 0.7 MPa or less.
- After the end of daily work or when the machine is not operated for a long time, be sure to shut off the
supply air and open the discharge port valve to bleed the internal pressure of the pump and hose.
Any secondary accident such as pollution of installation, due to hose damage or leakage from the
valve without shutting off the supply air, shall be attributable to the user’s responsibility.
- During machine operation or after completion of movement, be sure to lock
the caster brake for locking. A turnover of equipment may pollute the
installation. (Fig. 3)
- During oil change, take extreme care not to allow sand and dust to adhere on the suction tune of the
pump. If sand is mixed in the oil, it will give breakage to the pump and also damage to the important
machine.
1）Before starting oil supply, be sure to turn the knob of the grip meter
counterclockwise to reset to the “0” position. (If the short needle has not
been reset, turn the long needle to reset the short needle to “0”.)
2）The pump is operated by pulling the lever of the grip meter, and oil is
discharged. If the discharge oil pressure is so high as to cause splashes,
adjust the supply air pressure with the air regulator.
3）After completing the oiling work, be sure to shut off the air chuck and pull
the gun lever to bleed the internal pressure of the hose.
<NOTE>
On the attached grip meter, one turn of the long needle corresponds to 1
liter, and one turn of the short needle corresponds to 10 liters. Watching
the supply oil volume at hand, it is possible to supply 10 liters or more of
oil per minute.
[Oil Changing Work]
1) This machine is provided with an indicator to indicate the residual oil
volume. The indicator is positioned at 10 to 15 mm from the lid. As the
residual oil volume is running short, the indicator comes into contact with
the lid. At this time, supply oil additionally. (Fig. 5)
2) Release the 3 clasps on the top of the oil tank, and the lid can be removed
together with the pump Assy.
3) Supply oil directly into the oil tank (50 liters).
<NOTE>
Take extreme care not to allow sand and dust to adhere on the suction
tube and float of the pump.
4) Put the lid as it was and fix the oil tank and the lid with the 3 clasps.

5.2 Maintenance and Inspection
For lubrication of the pump, perform oiling once every 10 days with
lubricating oil. (Fig. 6)
Supply the lubricating oil as following.
1) Remove the air regulator.
2) Inject a few drops of lubricating oil (approx. 0.5 mL) into the air supply
port as shown in the figure at right. Use turbine oil class 1 ISO (VG-32)
or equivalent as the lubricating oil.
[Inspection]
-Oil is a fluid and easily polluted. Keep it clean at all times.
-To protect the flow meter, a filter is installed between the pump and the
flow meter. If filter clogging occurs, the oil flow is get worse. Clean the
filter sometimes. (Fig. 7)
-The oil-proof hose is a consumable product. Check it periodically. If any
blemish or leakage is found, replace the hose a little earlier.
-The packing of the pump will be worn away. Check and replace it at
least once a year.
6. Disassembly and Assembly
-When the pump operation becomes defective or stops, do not disassemble the pump thoughtlessly, but refer to
the item on P.4 (Troubleshooting and Corrective Measures), and judge the condition carefully and disassemble
only the minimum necessary parts.
-The air motor is rarely touched directly, so its failure rate is very low. The air motor does not need to be
disassembled. If disassembling is required, ask the dealer to disassemble the air motor.
WARNING
- Gasoline is a high-volatility material. Do not use gasoline to clean the pump in any case, otherwise it
may cause ignition or explosion.
- Before starting disassembling or inspecting the machine, be sure to shut off the supply air and open
the outlet valve to release the internal pressure of the machine.
- When washing parts, do not use such a liquid as corrodes aluminum, copper alloy, iron, etc.
