Precautions On Use - YAMADA SH-110A5 Operation Manual

- 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.
- 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.
- The operator and maintenance engineer should read the operation manual thoroughly before
operating the pump and performing maintenance in respect of this pump.
- 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.
- Be especially careful when pumping explosive material. Mixture of an air and vaporized material
can explode. If there is any possibility of running dry, install a dry-run protection device like a
liquid level control.
- 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 SDS 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.)
- (SH type only) If using a wall mount bracket for installation, the wall must be strong enough to
withstand vibration of the pump.
