safety must be dealt with immediately.
All of the manufacture’s safety, work and maintenance regulations as well as the given
norms in the Technical Data must be observed.
STATIC ELECTRICITY AND FILLING THE PETROL TANK
Static electricity can initiate from un-grounded petrol tanks or containers from flowing petrol and
persons carrying a static electric charge. Static electricity can explosively ignite petrol vapours that
are present during the fuelling process, resulting in serious burns to nearby persons.
Many objects can accumulate and retain a static electric charge. Objects made of non-conductive
materials (eg. plastics) easily accumulate and retain static electrical charge, as can objects made
of conductive material (eg. metal, water) if they are not electrically grounded.
To avoid static electricity while fuelling, certain steps must be followed before and during the
fuelling process in order to minimise and safely dissipate static charge build-up:
Touch a grounded metal object before starting. Always dissipate static charge from your
body before beginning the fuelling process by touching a grounded metal object at a safe
distance away from the fuel source.
Use a portable container to fill the tank. NEVER fill the engine’s petrol tank directly from
the fuel pump –the engine’s tank is not grounded and the high velocity flow of petrol
from a fuel pump can cause static electric build-up. Use an approved portable container to
transfer to the engine’s tank.
TYPICAL SOURCES OF STATIC ELECTRIC HAZARDS DURING FUELLING
The following objects can accumulate a static electric charge and cause an ignition spark in typical
fuelling situations:
Ungrounded tanks/containers.

Any ungrounded fuel tank or container can accumulate a static electric charge as a result of
contact with other objects or friction during transportation. This static electricity can discharge as
a spark to the grounded petrol dispenser nozzle as the nozzle is first brought close to the
tank/container at the beginning of the fuelling process.
Flowing petrol. Most people are not aware that petrol accumulates static electric charge
while flowing through a hose or pipe. This charge then transfers to and accumulates in the
gas tank or container that is being filled. The total amount of charge accumulation
depends on the amount of gas pumped into the container, the speed with which it is
pumped, and whether or not the tank/ container is grounded. If sufficient static electric
charge accumulates in the fuel tank or container during the fuelling process, the
tank/container may discharge a spark to the grounded petrol dispenser nozzle.
A person dispensing the petrol can carry a static electric charge on their body, typically
resulting from contact with their car seat or electronics. The static electricity can discharge
a spark between that person’s hand and either the grounded dispenser nozzle or the fuel
tank opening.
Before using the water pump, you must select a suitable OUTDOOR location for
installation and operation that meets the following criteria:
DRY, LEVEL SURFACE
The water pump should be positioned on a dry, firm and level surface. Ensure that the water
pump sits level and will not slide or shift during operation.
OUTDOORS ONLY
Follow the directions below for choosing a location to operate your water pump in order to avoid
carbon monoxide poisoning:
The location you choose to operate the water pump must be OUTDOORS and away from
all building air intakes.
Never run the water pump inside any closed or semi-enclosed spaces (even if outdoors),
including homes, garages, basements, sheds or boxes. These spaces can trap poisonous
gases, even if you run a fan or open windows.
Ensure that working, battery-operated or battery back-up carbon monoxide alarms are
used in any dwelling/structure that is in close proximity to the running operator.
ADEQUATE COOLING VENTILATION
The exhaust from your water pump contains carbon monoxide (CO), a poisonous gas that
can kill. You cannot smell it, see it or taste it. Breathing carbon monoxide can cause loss of
consciousness and may lead to death. Never run your water pump in a closed or even
partially enclosed areas or near open windows or doors. Never attempt to attach ductwork
to the muffler system to allow for installation inside an enclosre. This could cause hot air,
WARNING heat build up and increased exhaust back pressure, resulting in possible exhaust leackage
or damage to the water pump.

The water pump needs adequate, unobstructed flow of air to allow for proper cooling of the
engine and water pump head.
Never place the water pump immediately adjacent to a building or other structure –allow at least
2 metres clearance.
Do not run the water pump in close proximity to other heat-generating equipment, such as a
water pump. The combined heat that is generated may raise air temperature in the immediate
area and there will not be adequate cooling ventilation.
Do not allow debris to accumulate and block airflow.
Do not operate with a tarp, blanket, or cover surrounding the water pump.
HOT EXHAUST CLEARANCE
Make sure your water pumps exhaust system is at least 2 meters from all combustible materials
and buildings/structures.
Equip the engine with a spark arrestor if the water pump will be used near any ignitable forestry,
brush, bush or grassy land. (see the “Specifications” section of this manual to determine if your
water pump is already equipped). Make sure you comply with applicable local, state and federal
codes. Keep a fire extinguisher rated “ABC” nearby. Keep it properly charged and be familiar with
its use.
OPERATE AWAY FROM DUST/DIRT
Do not use the water pump in extremely dusty or dirty conditions. Excessive dust and dirt can
cause premature failure of the machine.
HEARING PROTECTION
Water Pumps can product noise levels >70dB in close proximity, which can be dangerous to
human hearing with prolonged exposure to the running water pump for an extended period of
time.
An Important Message about Temperatures
Your water pump is designed and rated for continuous operation at ambient temperatures up to
40 degrees Celsius. When your water pump is needed, it may be operated at temperatures
ranging from -15 degrees Celsius to 50 degrees Celsius for short periods. If the water pump is
exposed to temperatures outside this range during storage, it should be brought back within this
Heat build up from inadequate ventilation can result in fire, posting
a serious risk to nearby persons and structures. Situate so there is
adequate clearance around the water pump to allow for cooling
WARNING airflow so that heat does not build up.
Never attempt to attach ductwork to the muffler system to lower
noise levels. This could cause hot air deflection, heat build up and
increased exhaust back pressure, resulting in possible exhaust leakage
