This machine is a submersible water pump. The Wacker Neuson Submersible
Pump consists of an electric motor, an impeller, a strainer , an d a metal casing with
ports for water suction and discharge. Power is supplied to the pump through a
corded plug or a hard-wired connection, depending on the installation. The
operator connects hoses to the pump and routes them so that water is pumped
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’s specifications, and up to the flow, head, and
suction lift limits also stated within the product’s 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 rema in even after protective measures have been t aken.
They are called residual risks. On this machine, they may include exposure to:
■ Electric shock from improper electrical connections or high voltage
■ Personal injury from improper lifting techniques
■ 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.
