capabilities and limitations before operating this machine.
Do not exceed the maximum working pressure of the lowest rated system component. Refer to
“Technical Data” in Section 6 for the maximum working pressure of this equipment. This
equipment has a 4 bar (approximately 60 psi) maximum working pressure.
Use fluids and solvents that are compatible with the equipment wetted parts. Read the fluid and
solvent manufacturer’s warnings.

1-2. Pressurized Equipment Hazard
Spray from the gun/valve, hose leaks, or ruptured components can splash fluid in the eyes or on the
skin and can also cause serious injury.
Do not stop or deflect leaks with your hand, body, glove or rag.
Do not point the gun/valve at anyone or at any part of the body.
Follow the “Pressure Relief Procedure” in Section 4-5 whenever you:
oare instructed to relieve pressure
ostop dispensing
oclean, check, or service the equipment
oinstall or clean the nozzle
Tighten all fluid connections before operating the equipment.
Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts
immediately. Permanently coupled hoses cannot be repaired; replace the entire hose.
1-3. Moving Parts Hazard
CAUTION! Moving parts, such as the priming piston, can pinch or amputate your fingers.
Keep clear of all moving parts when starting or operating the pump.
Keep hands and fingers away from the priming piston during operation and whenever the pump
is charged with air.
Before servicing the equipment, follow the “Pressure Relief Procedure” in Section 4-5 to prevent
the equipment from starting unexpectedly.
Keep your hands away from the wiper plate and the lip of the fluid container while the ram is
operating.
Do not place your fingers into the air motor coupling cavity while the pump is operating.
Do not shut off the air supply to the ram while it is being raised. Doing so will cause the pump to
fall to the bottom in an uncontrolled manner.

3. Installation
Please open the windows for air ventilation before you operate the equipment in your working
room.
This equipment must be set 50cm x 50cm (20” x 20”) away from the wall or table corner.
If you supply your own accessories, be sure they are adequately sized and pressure-rated to
meet the system’s requirements (refer to “Technical Data” in Section 6).
3-1. Pump Location
Place the unit on a hard, level surface. Check that the unit is level in all directions. Ensure that
there is sufficient overhead clearance for the pump when the ram is fully raised. Leave room on
both sides so that the air regulators (13 and 4) will be easily accessible.
3-2. Main Air Supply
Connect the main air hose to the main air inlet fitting (14). The main air inlet fitting is designed for
φ6mm tubing. Be sure that the tube is securely connected, and will not come out when air
pressure is applied.
3-3. Wiper Plate
3-3-1. Raise the ram by setting the ram director valve switch (12) to the UP position and then
turning the ram air regulator (13) clockwise. The setting of the ram air regulator should be
increased enough to make the ram start moving up. Let the ram rise to its full height.
3-3-2. Place the wiper plate (5) on the base (9), making sure to align the center of the wiper plate
with the pump intake housing (6).
3-3-3. Set the ram air regulator (13) to zero to make the ram unit move downward. As the ram unit
slowly falls, guide the pump intake housing (6) onto the wiper plate (5).
3-3-4. Set the ram director valve switch (12) to the DOWN position.
3-3-5. Set the ram air regulator (13) to 10 psi (0.7 bar). Push down on the pump to install the wiper
plate (5) onto the intake housing (6).
3-3-6. Secure the wiper plate to the pump with the two screws (7).
3-3-7. Connect the air assist tube (15) to the air assist inlet fitting (2).
Be sure that the tube is securely connected, and will not come out when air pressure is applied. To
check, pull back gently on the tube to ensure that it will not get pulled out.

4. Operation
4-1. Starting and Adjusting the Ram
4-1-1. Set the ram air regulator (13) to zero.
4-1-2. Close the wiper plate bleed valve (3).
4-1-3. Be sure all air regulators and bleed-type air valves are closed.
4-1-4. Insert the main air hose into the main air inlet fitting (14) to supply air.
Please keep the fluid outlet valve (1) closed.
4-1-5. Open the valve in the main air supply.
4-1-6. Turn the ram air regulator (13) clockwise until the pressure becomes 28 psi (2 bar).
4-1-7. Set the ram director valve switch (12) to the UP position and let the ram rise to its full height.
You can see that the whole pumping part is moving up.
4-1-8. To change the speed at which the ram is raised and lowered, adjust the ram air regulator
(13) to increase or decrease the air pressure.
4-1-9. Check that the fluid can is not dented or out of shape, which will damage the wiper plate and
cause leakage around the wiper. Cut off the top of the fluid can with a can opener, or
remove the bottom of the can. Be sure that the edge is free of burrs, which will damage the
wiper plate. If necessary, bend the edge of the fluid can back with pliers so the wiper plate
will enter the can easily. Lubricate the wiper ring (8) to help the plate enter the can easily.
4-1-10. Align the center of the wiper plate (5) with the center of the can containing the liquid to be
dispensed.
4-1-11. Make sure that the fluid outlet valve (1) is closed.
4-1-12. Slowly open the bleed valve (3). This will allow air trapped under the wiper plate to escape
when the ram is lowered.
4-1-13. With your hands away from the lip of the can and the wiper plate (5), set the director valve
switch (12) to the DOWN position to lower the ram until the wiper plate enters the can.
Adjust the position of the can to ensure the center of the can is aligned with the center of the
wiper plate.
Always keep your hands away from the lip of the can and the wiper plate when the
ram is being lowered.

4-1-14. When the wiper plate enters the can, reduce the setting of the ram air regulator (13).
NOTE: If the wiper plate does not enter the can easily, increase the ram pressure by adjusting the
ram air regulator (13); once it enters the can, immediately reduce the pressure.
4-1-15. Continue to lower the ram. As soon as fluid appears at the wiper plate bleed valve (3) outlet,
close the wiper plate bleed valve (3).
4-1-16. Secure the can in place using the clamps (10).
4-2. Priming the Pump and Pumping Fluid
4-2-1. Make sure to close the fluid outlet valve (1) before operating the pump.
4-2-2. Connect the material hose to the fluid outlet valve (1). Be sure that the hose is securely
connected.
4-2-3. Make sure that the pump pressure regulator (4) is set to zero.
4-2-4. Set the ram air regulator (13) to about 22 psi (1.5 bar).
4-2-5. Turn the pump pressure regulator (4) clockwise to start pumping.
4-2-6. Open the fluid outlet valve (1) slowly to make the fluid come out through the material hose.
4-2-7. Adjust the pumping speed as needed by turning the pump pressure regulator (4) as follows:
- turn clockwise to increase the pumping speed
- turn counterclockwise to decrease the pumping speed
4-2-8. Keep the director valve switch (12) in the DOWN position while the pump is operating.
NOTE: Adjust the ram air pressure (13) as needed, but do not increase it to a level where fluid is
forced past the wiper plate.

4-3. Stopping the Pump and Removing the Fluid Can
4-3-1. To stop the pump, set the pump pressure regulator (4) to zero by turning the pump pressure
regulator (4) counterclockwise.
4-3-2. Close the wiper plate bleed valve (3).
4-3-3. Set the ram air regulator (13) to 30 psi (2.1 bar).
4-3-4. Open the fluid outlet valve (1) to relieve all fluid pressure in the system.
4-3-5. Set the director valve switch (12) to the UP position. This causes both the pump and the
can to move up simultaneously. Make sure the whole pumping part including the can is
moving up.
4-3-6. Separate the can from the wiper plate (5) by pressing the air assist valve button (11) slowly
and keep pressing it until the wiper plate (5) clears the top of the can.
By pressing the air assist valve button, air is supplied through the air assist inlet fitting (2).
NOTE: If the ram director valve switch (12) is set to the DOWN position, you will not be able to
separate the can from the rubber plate even though you are pressing the air assist valve
button (11), because the cylinders on both sides are being held down.
4-3-7. Remove the empty can.
If the fluid has been used up and the wiper plate is stuck inside the can , do not increase the
setting of the ram air regulator (13) to remove the plate. Excessive pressure in the can may
cause the can to rupture.
