1.2 Machine Description and Intended Use
This machine is a centrifugal dewatering pump. The Wacker Neuson
Dewatering Pump consists of a tubular steel frame surrounding a
gasoline engine, a fuel tank, and an impeller pump with ports for water
suction and discharge. The engine rotates the impeller during
operation. Waste 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 and solids are
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,
or water containing solids up to the size stated within the product
specifications, and 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 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
• Using the machine as a ladder, support, or work surface
• Using the machine to carry or transport passengers or equipment
• 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

PG 2A Safety Information
wc_si000415gb.fm 13
• Fuel and its fumes
• Personal injury from improper lifting techniques
• Projectile hazard from discharge
• Crushing hazards from a tipping or falling pump
To protect yourself and others, make sure you thoroughly read and
understand the safety information presented in this manual before
operating the machine.

1.3 Safety Guidelines for Operating the Machine
Operator qualifications
Only trained personnel are permitted to start, operate, and shut down
the machine. They also must meet the following qualifications:
• Have received instruction on how to properly use the machine
• Are familiar with required safety devices
The machine must not be accessed or operated by:
•Children
• People impaired by alcohol or drugs
Personal Protective Equipment (PPE)
Wear the following Personal Protective Equipment (PPE) while
operating this machine:
• Close-fitting work clothes that do not hinder movement
• Safety glasses with side shields
• Hearing protection
• Safety-toed footwear
• Do not touch the engine or muffler while the engine is on or
immediately after it has been turned off. These areas get hot and
may cause burns.
• Do not use accessories or attachments that are not recom-
mended by Wacker Neuson. Damage to equipment and injury to
the user may result.
• Do not pump volatile, flammable, or low flash point fluids. These
fluids could ignite or explode.
• Do not pump corrosive chemicals or water containing toxic sub-
stances. These fluids could create serious health and environ-
mental hazards. Contact local authorities for assistance.
• 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 radia-
tor 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.
WARNING Familiarity and proper training are required for the safe operation of the
machine. Machines operated improperly or by untrained personnel can be
hazardous. Read the operating instructions contained in this manual and the
engine manual, and familiarize yourself with the location and proper use of all
controls. Inexperienced operators should receive instruction from someone familiar
with the machine before being allowed to operate it.

PG 2A Safety Information

• Do not open pump housing cover while pump is operating, or
start 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 inlet line or discharge line.
Remove kinks from discharge line before starting pump. Opera-
tion with a blocked inlet line or discharge line can cause water
inside pump to overheat.
• Read, understand, and follow procedures in the Operator’s Man-
ual before attempting to operate the machine.
• Be sure operator is familiar with proper safety precautions and
operation techniques before using machine.
• Be sure the machine is on a firm, level surface and will not tip,
roll, slide, or fall while operating.
• Close fuel valve on engines equipped with one when machine is
not being operated.
• Store the machine properly when it is not being used. The
machine should be stored in a clean, dry location out of the reach
of children.
1.4 Operator Safety while Using Internal Combustion Engines
Operating safety
When operating the pump:
• Keep the area around exhaust pipe free of flammable materials.
• Check the fuel lines and the fuel tank for leaks and cracks before
starting the engine.
WARNING
Internal combustion engines present special hazards during operation and fueling.
Failure to follow the warnings and safety standards could result in severe injury or
death.
►Read and follow the warning instructions in the engine owner’s manual and the
safety guidelines below.
DANGER
Asphyxiation hazard. Using a pump indoors CAN KILL YOU IN MINUTES. Pump
exhaust contains carbon monoxide. This is a poison you cannot see or smell.
Ñ NEVER use this pump inside a home or garage, EVEN IF doors and windows
are open. Only use OUTSIDE and far away from windows, doors, and vents.
►NEVER use a pump inside an enclosed area, such as a tunnel or a trench,
