Operating Instructions
For Darley “DOLPHIN” Floating Fire Pump
Do not use this pump for hose testing. Such testing could
result in major pump or engine damage. Such damage may cause
explosion, overheating of the engine and/or pump, and bodily harm.
PREPARATIONS FOR PUMPING
Make sure to read the engine instruction manual before usage.
Check the engine oil level before starting the engine.
Check the fuel level before starting the engine.
Do not run the pump dry or at high speed unless it is placed in water of adequate
depth.
Connect the discharge hose to the pump.
Ensure the discharge breather check valve; located near the Darley emblem on
the float; is working, clean and clear of debris.
Start the engine.
Place float pump in the water immediately after starting. This Float pump is self-
priming due to a flooded suction. The pump will prime more quickly if the engine
is run at lower speeds.
Slowly open the engine throttle once the pump is primed and discharging water.
Recommendations
Do not allow unusual elevation of the discharge hose, this may
cause the float to overturn.
When pumping salt water or dirty water, flush pump with clean water after usage.
