• 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.
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.
• 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.
