- Precautions on Use
The following warnings and cautions are very important. Be sure to observe them.
WARNING
- Keep your face away from the exhaust and discharge ports. Material may suddenly come out. There is
a possibility of losing eyesight if it strikes eyes.
- Keep your face and hands away from the outlet when handling the check valve. Air-containing material
may suddenly come out. There is a possibility of losing eyesight and injuring the hand.
- Do not aim exhalation part of this product at any person. Residual pressure may be left inside the gun
even when the pump is not in operation. There is a possibility of losing eyesight if it strikes eyes.
- Gasoline is a high volatile fuel. Do not use it to clean the pump in any case, otherwise ignition or
explosion may be caused.
- Modification of this pump may lead to death, bodily injury, or a failure. Do not modify it in any case
because it involves a risk.
- Do not ride this product. There is a risk of falling.
- The operator and maintenance engineer should read the operation manual thoroughly before operating
this product and performing maintenance in respect of this product.
- Always wear proper safety equipments (facemask, ear plugs, and safety shoes, etc.) when installing,
operating, and disassembling this product.
- Make sure the casters are locked during and after work to prevent unexpected movement of this
product. Also, do not use or leave this product in a slope or any unstable locations. The product, if not
locked, may move unpredictably, causing property damage or facility pollution. The user has a
responsibility for such secondary accidents.
- Make ground connection when working with flammable material or in explosive atmosphere. Rapid
pumping of material can result in static electrical charge. Also, be sure to provide proper ventilation
where a flammable atmosphere may exist.
- Execute the daily checkup.
- Use this product according to the product specification.
- Attach a valve (for stop in emergency) or regulator to the air supply pipe to keep supply air pressure
under 0.7MPa.
- If there is any danger or abnormality, discontinue pump operation and refer to Troubleshooting to solve
the problem.
- Stop pump operation immediately when a drum becomes empty. Running the pump dry will cause
excessive vibration, resulting in reduction of pump life and damage to other equipment.
- Before maintenance involving disassembly, be sure to shut off air supply to the pump and release
residual air pressure and material pressure in the tubes and pump. Failure to do so may result in
material gushing out.
- Do not discharge material directly onto the ground. Dispose of harmful materials according to the
requirements specified in MSDS or local regulations. Also, dispose of this product according to the local
regulations after removing residual material from inside this product. (Please contact industrial waste
disposal service.)

3/ 3
CAUTION
- Keep hands and fingers away from this product during operation to avoid injury from moving parts.
- Use this product for the material suitable for the specification. Parts may be corroded and material leak
from the damaged parts can lead to environmental pollution. Also, follow handling notes (MSDS) of the
manufacturer about the handling of the material used.
- Take protective measures against rainwater and dust. It is likely to lead to the pollution of the material.
- Watch your step around this product to avoid tripping over the base and casters.
- Be careful about your hands when installing a pail. The edges of the cabinet and pail may cause hand
injury. Also, be careful about your posture when moving the pump to avoid back injury.
- Do not touch the surfaces of the pump and the hose when pumping high-temperature material. Risk of
burns exists.
- Shut off air source after work and nighttime, holidays, or when the pump is not in use for a while. Also,
open the valve at the discharge port to release residual pressure in the pump and hoses. Failure to do
so may result in damage to the hoses or facility pollution due to leak from the valve. The use has a
responsibility for such secondary accidents.

2. Preparations before Use
2.1 Assembling the machine
1) Casters are packed separately. Insert them into the caster base and
secure with the supplied bolts, plain washers, and spring lock
washers. (Fig. 1)
2) The rubber cap is put on the suction section of the pump
(inside the inductor plate) for protection.
Be sure to remove this rubber cap before using the machine.
3) Attach the supplied air regulator onto the union adapter located at
the air inlet of the pump. (Fig. 2)
4) Attach the provided air tube for the lift to the fitting located at the air
inlet of the pump. Make sure it wouldn’t be pulled out. (Fig. 2)
5) Connect a high-pressure grease hose to the grease outlet (check
valve) and tighten it securely. (Fig. 2)
＜NOTE＞
- A high-pressure grease hose is not provided in this product.
Purchase our authorized genuine hose separately. A high-pressure
grease gun or metering valve can be attached to the hose outlet.
Select and purchase appropriate dispensing equipment depending
on the intended use.
6) Attach the supplied air coupler onto the air hose connected to the
compressor, and fix it with the hose band or similar device.
2.2 Setting a grease pail
1) Remove the bleeder plug from the inductor plate. (Fig. 3)
2) Shut off the air valve of the pump unit. Then, turn the controls of
both regulators (pump and lift) to the left (counterclockwise) to
loosen them. (Fig. 3)
Set the control of the lift up/down switch to “DOWN”. (Fig. 4)
＜NOTE＞
- The air regulator allows you to adjust the pressure of air to be
supplied to the pump, and it reduces the waste motions of the pump:
it improves the operability of the pump and extends the life of the
pump.
To adjust the air pressure with the air regulator, turn the control to
the right. The air pressure increases (the pointer of the pressure
gauge moves from “0” to the larger value). When you turn the
control to the left, the air pressure decreases (the pointer of the
pressure gauge returns to “0”).

3) Connect the air hose prepared at Section 2.1 6) to the air supply
inlet, and supply air to the machine. (Fig. 5)
4) Turn the control of the lift air regulator gradually to the right
(clockwise) to set the indicator at 0.4MPa-0.5MPa (within normal
service pressure). (Fig. 6)
5) Switch the control of the lift up/down switch to “UP”. The lift moves
upwards. (Fig. 7)
When the lift moves upwards, it indicates that you have made the
preparation for setting a grease pail.
6) Remove the lid of a new grease pail, and set the pail onto the base
section of the pump unit properly.
＜NOTE＞
- If you do not set a pail properly, grease is not discharged. Be sure to
set it on the correct position.
7) Switch the control of the lift up/down switch to “DOWN”. The lift
slowly moves down due to the pump’s own weight. Adjust the
position of the pail so that the inductor plate can be set normally.
(Fig. 8)
CAUTION
- Do not put your hands and fingers between a pail and the
inductor plate to prevent injuries from being caught.
8) Switch the control of the lift up/down switch to “DOWNWARD
PRESSURE”. (Fig. 9)
Once grease pressurized by the inductor plate comes out of the
bleeder plug hole, switch the control of the up/down switch to
“DOWN” to stop pressurizing temporarily and attach the air bleeder
plug.
CAUTION
- When you simply want to lower the lift, do NOT set the
control switch to the “DOWNWARD PRESSURE” to move
the lift.

2.3 Bleeding air from grease
WARNING
- Keep your face and hands away from the outlet when handling the check valve. Air-containing material
may suddenly come out. There is a possibility of losing eyesight and injuring the hand.
＜NOTE＞
- Unlock the control of the regulator by pulling before turning it for
pressure setting. Once you set air pressure, press the control in to
lock it.
1) Make sure that the valve at the discharge outlet is closed.
2) Open the air valve and turn the control of pump air regulator
gradually to the right (clockwise). The pump will start at 0.2MPa
and run for a while until the pump and hose are filled with grease.
(Fig.10)
3) At first, air is trapped in grease, which is not ready for use. Open the
check valve at the discharge outlet and allow the trapped air to
escape completely from the small hole at the bottom of the valve. At
this time, put some paper to protect your hand from grease and
dispose of discharged grease. (Fig.11)
＜NOTE＞
- Grease mixed with air is cloudy.
4) After purging the trapped air from grease, tighten the check valve
securely.
