Page 12: Transportation
Transportation “Transport” refers to the phase when the equipment is transferred from the manufacturing site to that where it shall be used. The electrical equipment is supplied mechanically fastened to the structure of its relative machine; refer to the specific Use and Maintenance Manual for the methods of transport and handling. Any kind of impact and stress to the components must be avoided when the equipment is transported and handled. -
Page 13: Pipework And Installation
Clean pipework thoroughly before connecting it to the pump. Suction pipes must have the same diameter as the pump’s suction port (for larger diameters, seek Koshin pump advice). Where possible, avoid curves, elbows or constrictions liable to limit the flow of liquid to the pump. -
Page 14: Fill The Fuel
Fill the fuel WARNING Perform this operation Engine must be switched off and cooled down. Filling the Fuel not smoking or be near at open fire. 1. Open the fuel tank cup (1), visually inspect fuel level if necessary, fill it. -
Page 15: Preparation For Starting

Page 18: Starting
Starting 1. Check the pump type (type plate) and the characteristics of the pump unit, such as: rpm, operating pressure, power consumption, operating temperature, direction of rotation, NPSH, etc. Check whether the pump unit is placed in accordance with the instructions. Pay particular attention to the area around the pump unit. - Page 19 12. When motor is started open choke lever (4). Engine pick up nominal speed and start running smoothly. WARNING If vibration occurs during starting, stop the pump immediately and eliminate the cause before starting again. WARNING If the pump vacuum lift is set too high, cavitation in the pump set is possible and this can be recognized by High levels of vibration, a crackling noise in the pump, decreased capacity and pressure.
