Water Pump

 2.1.1 — Exhaust Hazards

Carbon monoxide produced during use can 
kill in minutes. NEVER use indoors, in a vehi-
cle, or in other sheltered areas, EVEN IF doors 
and windows are open. Only use OUTSIDE 
and far away from windows, doors and vents.

• Operate water pump ONLY outdoors.

• A running engine gives off carbon monoxide.

• Carbon monoxide is an odorless, colorless, poisonous 

gas. Breathing carbon monoxide can cause headache, 
fatigue, dizziness, vomiting, confusion, seizures, nau-
sea, fainting or death. If you start experiencing any of 
these symptoms, IMMEDIATELY move to fresh air. 
Seek medical attention.

• Keep exhaust gas from entering a confined area 

through windows, doors, ventilation intakes, or other 
openings. Warn any occupants inside about the symp-
toms of carbon monoxide so they know to move to 
fresh air if they begin to feel ill.

• The use of a carbon monoxide detector inside any 

occupied premises between the water pump and the 
occupant is recommended.

• NEVER start or run engine indoors, in a vehicle, or in 

an enclosed area, even if windows and doors are open.

• Use a respirator or mask whenever there is a chance 

that harmful gas or vapors may be inhaled.

• Read all instructions with respirator or mask so you are 

certain the respirator or mask will provide the neces-
sary protection against inhaling harmful gas or vapors. 
If you begin to experience any of the CO symptoms 
listed above, IMMEDIATELY move to fresh air.

 2.1.2 — Electrical Shock Hazard

Risk of electrocution.

Contact with power source can cause electric 
shock or burn.

• NEVER have discharge hose near power source.

 2.1.3 — Hot Surfaces Hazard

Contact with muffler area can result in 
serious burns. Exhaust heat/gases can 
ignite combustibles, structures or 
damage fuel tank causing a fire.

• DO NOT touch hot parts and AVOID hot exhaust 

gases.

• Allow equipment to cool before touching.

• Keep at least five (5) feet (152 cm) of clearance on all 

sides of water pump including overhead.

• It is a violation of California Public Resource Code, 

Section 4442, to use or operate the engine on any for-
est-covered, brush-covered, or grass-covered land 
unless the exhaust system is equipped with a spark 
arrester, as defined in Section 4442, maintained in 
effective working order. Other states or federal jurisdic-
tions may have similar laws. Contact the original equip-
ment manufacturer, retailer, or dealer to obtain a spark 
arrester designed for the exhaust system installed on 
this engine.

• Replacement parts must be the same and installed in 

the same position as the original parts.

 2.1.4 — Fire Hazards

Fuel and its vapors are extremely flam-
mable and explosive. Fire or explosion 
can cause severe burns or death.

WHEN ADDING OR DRAINING FUEL

• Turn water pump OFF and let it cool at least two (2) 

minutes before removing fuel cap. Loosen cap slowly 
to relieve pressure in tank.

• Fill or drain fuel tank outdoors.

• DO NOT overfill tank. Allow space for fuel expansion.

• If fuel spills, wait until it evaporates before starting 

engine.

• Keep fuel away from sparks, open flames, pilot lights, 

heat, and other ignition sources.

• DO NOT light a cigarette or smoke.

WHEN STARTING EQUIPMENT

• Ensure spark plug, muffler, fuel cap, and air cleaner 

are in place.

• DO NOT crank engine with spark plug removed.

• Keep your hands and body clear from the discharge of 

the pump.

• Make sure all connections are tight.

• Secure the pump. Loads from the hoses may cause it 

to tip over.

• Secure the discharge hose to avoid whipping.

WHEN OPERATING EQUIPMENT

• DO NOT tip engine or equipment at angle which 

causes fuel to spill.
