WARNING
READ and UNDERSTAND this manual completely before using the water pump! Failure to properly set
up, operate, and maintain this water pump could result in serious injury or death from carbon monoxide
poisoning, electric shock, fire/explosion, or burns. In particular, be aware of the following hazards:
CO Poisoning
Water pumps give off carbon monoxide, a poisonous gas that can kill you. You CANNOT smell it, see it, or taste it.
ONLY run water pump OUTDOORS and at least 20 feet from the home, away from windows, vents and air intakes, to
allow proper ventilation. 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. NEVER run water pump inside any enclosed or semi-enclosed spaces, including homes,
basements, garages, sheds, boxes, RVs, boats or pick-up truck beds. These spaces can trap poisonous gases, EVEN if
you run a fan or open windows.
Install carbon monoxide alarms inside nearby structures/buildings (battery-operated, or plug-in with battery backup).
Fire / Explosion
DO NOT overload water pump (per rated capacity), and OPERATE ONLY in an area with adequate cooling ventilation
so engine does not overheat. Exhaust can be extremely hot. Keep muffler at least 7 feet from all combustible objects.
All fuels are flammable. Never fuel a running or hot engine. Never pump fuel directly into water pump at gas station –
use approved container to transfer fuel. Ensure there are no fuel leaks, and keep sources of sparks and flames away.
ALWAYS keep a fire extinguisher rated “ABC” nearby.
NEVER pump flammable liquids.
STOP!
INSPECT COMPONENTS: Closely inspect to make sure no components are missing or damaged. See
the “Unpacking & Delivery Inspection” section for instructions on whom to contact to report missing or
damaged parts.
ADD ENGINE OIL: Engine is shipped without oil. See engine section of this manual for instructions on capacity and
viscosity recommendations.
