- Preface

Thank you very much for purchasing Yamada Pump.

- This 110 type pump is a grease pressure-feed pump.

- In the normal operating condition, the pump permits using up to NLGI No.0 grease. When the pump is
operated in a very cold or low-temperature environment, the discharge volume is remarkably lowered. In such
a case, we shall not guarantee the discharge volume of the pump.

- Silicone grease is not applicable. (PD110A50T-SL is excluded.)

- For Safe Operation

This manual describes the items that are important for the user to operate this product safely, correctly, and
efficiently. Before operating this product, read this manual thoroughly, in particular, “Warnings and Cautions”

This indicates the existence of potential hazard which, if not avoided, may
result in bodily injury or in physical damage.

- Precautions on Use

The following warnings and cautions are very important. Be sure to observe them.

- 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.

- Gasoline is a high volatile fuel. Do not use it to clean the pump in any case, otherwise ignition or
explosion may be caused.

- Keep your fingers away from each port to avoid injury from moving parts.

- 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.

- Keep your hands away from shovel(the lowest part of the pump). During operation to avoid hand
injury resulting from being caught in shovel.

- The operator and maintenance engineer should read the operation manual thoroughly before
operating the pump and performing maintenance in respect of this pump.

2/3

WARNING

- Always wear proper safety equipments(facemask, ear plugs, and safety shoes, etc.) when
installing, operating and disassembling the pump.

- 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 pump 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 0.7 MPa.

- Discontinue it when you feel a hazard or abnormality during the work. And correspond according
to the troubleshooting.

- 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 operation, be sure to stop air from being supplied to the pump, and release
the internal pressure (both air and material) of the pump. There is danger such as spouting of the
material when the maintenance work is done with air supplied.

- 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 pump according to the local
regulations after removing residual material from inside pump. (Please contact industrial waste
disposal service.)

3/3

CAUTION

- Keep hands and fingers away from the pump during operation to avoid injury from moving parts.

- Use pump 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 fall-prevention measures if using a slim or light tank. Risk of falling will be increased due to
shift in center of gravity caused by change in the material level in a tank.

- Take protective measures against rainwater and dust. It is likely to lead to the pollution of the
material.

- Be very careful about the edge of the pump when you lift the pump. Your hands might be injured.

- Be very careful about your posture when installing the pump. Back injury may be caused by lifting
the pump.

- Do not touch the surfaces of the pump and the hose when pumping high-temperature material.
Risk of burns exists.

- Stop the air supply source after the end of work when not using this pump for a long time such as
nighttimes and holidays. Also, open the valve of the exhalation port and liberate pressure in the
pump and the hose. There is a possibility of polluting facilities because of the damage of the hose
and the leakage of the valve. Such a secondary disaster becomes a responsibility on the user side.

- Place a drum on a flat, level surface to position pump horizontally against a ground. Operating the
pump on a slope may cause a fall or tip-over due to shift in center of gravity caused by change in
the material level.

- Material remaining inside or on the surface of the pump may spill out by inserting or removing the
pump into/from a drum. Be very careful not to get your clothing dirty.
