---------------------------- DURING FUELING/REFUELING ---------------------
Fuel outdoors. Fill fuel tank outdoors – never indoors. Gasoline vapors can ignite if they collect inside an
enclosure. Explosion can result.
Use approved container. Never pump fuel directly into engine at gas station. Static charge can build and
ignite fuel. Use an UL approved fuel container to transfer gas to the engine.
Running / hot engine. A running engine is hot enough to ignite fuel. Never add fuel or remove gas cap if
engine is running or still hot. Stop the engine and allow it to cool, at least two minutes before adding fuel.
Heat / flames / sparks. Stay away from sources of heat, flame, or sparks while adding fuel.
Don’t overfill. DO NOT overfill the gas tank.
Replace cap. Replace gas cap securely before starting engine.
Spills. Clean up fuel spills immediately. Move water pump away from spilled fuel on the ground. Wipe fuel
off engine and wait 5 minutes for excess fuel to evaporate before starting engine. Gas soaked rags should be
disposed of properly.
On skin / clothes. If gasoline is spilled on your skin or clothes, change clothes and wash skin immediately.
Gasoline storage. Store gasoline in a cool, dry place in an UL approved, tightly sealed container.
------------------------------------- DURING OPERATION ------------------------------
INSPECT and PREPARE water pump before each use as directed in this manual.
DO NOT USE flammable or corrosive chemicals in the water pump.
DO NOT RUN water pump while unattended.
FOLLOW INSTRUCTIONS for SAFELY FUELING/REFUELING THE ENGINE. Gasoline is
flammable and can explode. Always use caution when handling gasoline.
DO NOT START water pump until ready to use in order to avoid unintentional release.
SEE Troubleshooting section of this manual before attempting any repairs. Wear personal protective
equipment and follow safety instructions.
Hot muffler. If you are starting a warm engine, stay clear of muffler. It may still be hot enough to burn you.
Unattended. Never leave the machine unattended while the engine is running.
Under the influence. Never operate, or let anyone else operate, the water pump while under the influence of
alcohol, drugs, or medication.
Adjusting/Repairing. Turn off engine and remove spark plug cap before cleaning, inspecting, or servicing the
water pump.
Carbon monoxide. The running engine gives off carbon monoxide, a poisonous gas that can kill you. You
CANNOT smell it, see it, or taste it. If you start to feel sick, dizzy, or weak while using the water pump, shut
off the engine and get to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.
