IMPORTANT SAFETY INSTRUCTIONS
IMPORTANT SAFETY INSTRUCTIONS
WARNING
Cancer and Reproductive Harm – www.P65Warnings.ca.gov
DANGER
Water pump engine exhaust contains carbon monoxide,
a colorless, odorless, poison gas. Breathing carbon monoxide
will cause nausea, dizziness, fainting or death.
If you start to feel dizzy or weak, get to fresh air immediately.
OPERATE THE WATER PUMP OUTDOORS ONLY IN A WELL
VENTILATED AREA AND POINT EXHAUST AWAY.
DO NOT operate the water pump inside any building, including
garages, basements, crawlspaces and sheds, enclosure
or compartment, including the storage compartment of a
recreational vehicle.
DO NOT allow exhaust fumes to enter a confined area through
windows, doors, vents or other openings.
DANGER
Rotating parts can entangle hands, feet, hair, clothing and/or
accessories. Traumatic amputation or severe laceration can
result.
Keep hands and feet away from rotating parts.
Tie up long hair and remove jewelry.
Operate equipment with guards in place.
DO NOT wear loose-fitting clothing, dangling drawstrings or
items that could become caught.
WARNING
Spark from removed spark plug wire can result in fire or
electrical shock.
When servicing the water pump:
Disconnect the spark plug wire and place it where it cannot
contact the plug or any other metal object.
DO NOT check for spark with the plug removed.
DANGER
Using an engine indoors CAN KILL YOU IN MINUTES. Engine
exhaust contains carbon monoxide. This is a poison you cannot
see or smell.
NEVER use inside a home or garage, EVEN IF doors and
windows are open.
ONLY use OUTSIDE and far away from windows, doors,
and vents.
Install battery-operated carbon monoxide alarms or plug-in
carbon monoxide alarms with battery back-up according to the
manufacturer’s instructions.
Use only approved spark plug testers.
WARNING
Contact with electrical power source can cause electric shock
or burn.
NEVER spray in the direction of or near a power source/
electrical outlet.
WARNING
Running engines produce heat. Severe burns can occur on
contact. Combustible material can catch fire on contact.
DO NOT touch hot surfaces.
Avoid contact with hot exhaust gases.
Allow equipment to cool before touching.
Maintain at least 3 ft. (91.4 cm) of clearance on all sides to
ensure adequate cooling.
Maintain at least 5 ft. (1.5 m) of clearance from combustible
materials.

DO NOT use hoses or connectors that are worn, damaged or
frayed.
DO NOT allow children or unqualified persons to operate or
service the water pump.

result.
CAUTION
Improper treatment or use of the water pump can damage it,
shorten its life and void your warranty.
Use the water pump only for intended uses.
Operate only on level surfaces.
DO NOT expose water pump to excessive moisture, dust,
or dirt.
DO NOT allow any material to block the cooling slots.
DO NOT use the engine if:
– Equipment sparks, smokes or emits flames
– Equipment vibrates excessively
WARNING
Use of this water pump can create wet, slippery walking
surfaces.
– Use only on a level surface.
– Make sure there is proper drainage to dissipate water.
When starting engine, pull the starter cord slowly until
resistance is felt and then pull rapidly to avoid kickback.
WARNING
DO NOT pump salt, sludge, sewer, sea, or any other type of
water containing solid material.
CAUTION
Exceeding the pump specification for total head can damage
the pump and/or hose kits connected to it.
DO NOT modify the pump in any way. DO NOT attempt to
exceed the rated flow. Attempting to increase the rated flow
may damage the unit and/or shorten its life.
NOTICE
DO NOT run the pump dry.
Running the pump dry can destroy the pump seals and will
void the warranty. If the pump was running while dry, stop
the engine and allow it to cool thoroughly before filling the
chamber with water.

IMPORTANT SAFETY INSTRUCTIONS
Fuel Safety
DANGER
GASOLINE AND GASOLINE VAPORS ARE HIGHLY
FLAMMABLE AND EXPLOSIVE.
Fire or explosion can cause severe burns or death.
Gasoline and gasoline vapors:
– Gasoline vapors are highly flammable and explosive.
– Gasoline vapors can cause a fire or explosion if ignited.
– Gasoline is a liquid fuel and the resulting gasoline vapors can
ignite and cause a fire or explosion.
– Gasoline is a skin irritant and needs to be cleaned up
immediately if spilled on skin or clothes.
– Gasoline has a distinctive odor, this will help detect potential
leaks quickly.
– In any petroleum gas fire, flames should not be extinguished
unless by doing so the fuel supply valve can be turned OFF.
This is because if a fire is extinguished and a supply of fuel is
not turned OFF, then an explosion hazard could be created.
– Gasoline vapors expand and contract with ambient
temperatures. Never fill the gasoline tank past the red FULL
indicator on the fuel filter, as gasoline vapors needs room to
expand if temperatures rise.
WARNING
When starting the engine:
Do not attempt to start a damaged engine.
Always check that the gasoline cap, air filter, spark plug, fuel
lines and exhaust system are properly in place.
Always allow spilled gasoline to evaporate fully before
attempting to start the engine.
Always be certain that the water pump is resting firmly on level
ground.
WARNING
When operating the water pump:
DO NOT move or tip the water pump during operation.
DO NOT tip the water pump or allow fuel or oil to spill.
WARNING
When transporting or servicing the water pump:
Always check that the fuel valve is in the OFF position and the
gasoline tank is empty.
Disconnect the spark plug wire.
WARNING
WARNING
When adding or removing gasoline:
Do not light or smoke cigarettes.
Always stop the engine and allow to cool for a minimum of two
minutes before refueling.
Always loosen gasoline cap slowly to release vapor pressure
and to keep fuel from escaping around the gasoline cap.
Always replace and tighten the gasoline cap securely after
fueling.
Never remove the gasoline cap or add gasoline while the
engine is running or when the engine is hot.
Only fill or drain gasoline outdoors in a well-ventilated area.
Do not pump gasoline directly into the engine at the gas
station.
Always store gasoline in an EPA/CARB compliant container or
to transfer the gasoline to the engine.
Do not overfill the gasoline tank.
Always keep gasoline away from sparks, open flames, pilot
lights, heat and other sources of ignition.
When storing the water pump:
Store away from sparks, open flames, pilot lights, heat and
other sources of ignition.
Do not store water pump or gasoline near furnaces, water
heaters, or any other appliances that produce heat or have
automatic ignitions.
DANGER
Never place a gasoline container, gasoline tank, LPG cylinder
or any combustible material in the path of the exhaust stream
during operation of the engine.
WARNING
NEVER use a gasoline container, gasoline tank, or any other
fuel item that is broken, cut, torn or damaged.
