7. Operation
WARNING
•Fuel(Gasoline) is highly flammable and incorrect handling will cause fire accident. Strictly avoid smoking or fire during mixing or supplying the fuel.
•Be sure to stop the engine and allow it to be cooled before refueling.
•Spilled fuel shall be completely wiped away with wiping cloth, etc. before restarting the engine.
•Do not leave any flammable object around engine exhaust port.
WARNING
Before starting the engine, check if there is anything that must not be wet near the discharge hose tip. Give warning to nearby people of starting water discharge.
IMPORTANT
•Idle operation with no water in the pump may cause pump damage. Before starting the engine, check if the pump is filled with self- suction(priming) water. In case the suction strainer comes out of the water level during operation, immediately reduce the engine speed and stop the operation.
•Confirm that the suction hose connection is not too loose. Loose connection may result in no suction water.
•In case the discharge hose is clogged or a valve connected to the discharge hose is closed, the pump may not suck water.
•Stepping on the discharge hose or sudden closure of the discharge valve may create instantaneous high pressure in the pump and result in pump damage(Water Hammer Effect). Arrange protective covers if the hose can be disturbed by others stepping on, and avoid closing the valve rapidly.
