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 / 3A Safety Information
wc_si000069gb.fm 11
• Fuel and its fumes
• Personal injury from improper lifting techniques
• Projectile hazard from discharge
• Crushing hazards from a tipping or falling pump
