This document serves as a user manual for the MSW-GP-100 and MSW-GP-110 Gasoline Water Pumps, providing essential information for safe and trouble-free operation, technical specifications, and maintenance guidelines.
Function Description
The MSW-GP-100 and MSW-GP-110 Gasoline Water Pumps are designed for pumping water. They are free-standing units that require hoses with adapters to be connected to the water intake and outlet ends before use. A water filter must be placed on the end of the water intake hose. The pump is cooled by the water flowing through it during operation, so it must not be started dry to avoid overheating and damage. If the pump sucks air after pumping water, it should be turned off immediately, and cool water should be poured into the pump through the filler plug to cool it down. The pump's efficiency is maximized when placed as close as possible to the water source.
