1.2 Machine Description and Intended Use
This machine is a centrifugal de-watering pump. The Wacker Neuson Pump
consists of a gasoline engine, handle, frame, and an impeller with ports for water
suction and discharge. The engine rotates the impeller during operation. Water is
drawn into the pump through the suction port and expelled through the discharge
port. The operator connects hoses to the pump and routes them so that water is
drained from the work area and discharged into an appropriate location.
This machine is intended to be used for general de-watering applications. This machine
is intended for the pumping of clear water up to the flow, head, and suction lift limits also
stated within the product specifications.
This machine has been designed and built strictly for the intended use described
above. Using the machine for any other purpose could permanently damage the
machine or seriously injure the operator or other persons in the area. Machine
damage caused by misuse is not covered under warranty.
The following are some examples of misuse:
■Pumping flammable, explosive, or corrosive fluids
■Pumping water containing solids
■Pumping hot or volatile fluids that result in pump cavitation
■Operating the pump outside of product specifications due to incorrect diameter
hoses, incorrect length hoses, other inlet or outlet restrictions, or excessive
suction lift or head
■Operating the machine outside of factory specifications
■Operating the machine in a manner inconsistent with all warnings found on the
machine and in the Operator’s Manual
This machine has been designed and built in accordance with the latest global
safety standards. It has been carefully engineered to eliminate hazards as far as
practicable and to increase operator safety through protective guards and labeling.
However, some risks may remain even after protective measures have been taken.
They are called residual risks. On this machine, they may include exposure to:
■Heat, noise, exhaust, and carbon monoxide from the engine
■Fire hazards from improper refueling techniques
■Fuel and its fumes
■Projectile hazard from discharge
To protect yourself and others, make sure you thoroughly read and understand the
safety information presented in this manual before operating the machine.

Safe
operating
practices
■Do not open the priming plug when the pump is hot. Do not loosen or remove
inlet or discharge hose fittings when the pump is hot. Hot water inside could be
pressurized much like the radiator on an automobile. Allow the pump to cool to
the touch before loosening the plug and before loosening or removing the inlet
or discharge hose fittings.
■Do not position the pump on a loose, uneven, or unstable surface where it can
tip, roll, slide or fall! The pump must be secure before operating. Position the
pump on a firm, flat surface.
■Do not open the pump housing cover while the pump is operating or start the
pump with the cover off. The rotating impeller inside the pump can cut or sever
objects caught in it.
■Do not block or restrict flow from the inlet line or the discharge line. Remove
kinks from the discharge line before starting the pump. Operation with a blocked
inlet line or discharge line can cause water inside the pump to overheat.
■Do not reach into or insert anything into the pump while the engine is on! The
impeller inside the pump housing is turning at all times while the engine is
running.
■Do not allow anyone to stand in front of the discharge port when starting the
engine or while priming the pump.
■Always make sure the hose connections on the pump are tight. A loose
connection could cause water to spray or result in a hose falling off the pump
while it is in operation.
■Always make sure the water stream from the pump discharge is not directed in
such a way so as to cause erosion to the surrounding ground or damage or
weakening of nearby structures.

3.4 Recommended Fuel
This engine is certified to operate on automotive unleaded gasoline. Use only
fresh, clean gasoline. Gasoline containing water or dirt will damage fuel system.
Use of
oxygenated
fuels
Some conventional gasolines are blended with alcohol. These gasolines are
collectively referred to as oxygenated fuels. If you use an oxygenated fuel, be sure
it is unleaded and meets the minimum octane rating requirement.
Before using an oxygenated fuel, confirm the fuel’s contents. Some states and
provinces require this information to be posted on the fuel pump.
The following is the Wacker Neuson approved percentage of oxygenates:
ETHANOL - (ethyl or grain alcohol) 10% by volume. You may use gasoline
containing up to 10% ethanol by volume (commonly referred to as E10). Gasoline
containing more than 10% ethanol (such as E15, E20, or E85) may not be used
because it could damage the engine.
If you notice any undesirable operating symptoms, try another service station, or
switch to another brand of gasoline.
Fuel system damage or performance problems resulting from the use of an
oxygenated fuel containing more than the percentages of oxygenates mentioned
above are not covered under warranty.

Submerge the
hose
4. Submerge the suction hose.
■Always keep the strainer suspended in the liquid being pumped.
■Do not run the pump in less than 100 mm (4.0 in.) of water. At this level and
lower, water begins to form a funnel down to the bottom of the suction line
and strainer, allowing the pump to draw in air. The mixture of air and water
leads to a condition known as cavitation, which will quickly destroy the
impeller and the water chamber inside the pump housing.
Connect the
discharge
hose
Connect the discharge hose (d) to the discharge port (e).
Note: Lay the discharge hose as straight as possible. Avoid sharp bends and
turns.
Prime the
