Safety Information PDI2A/3A / PDT2A/3A
1.2 Machine Description and Intended Use
Machine
description
This machine is a diaphragm pump. The Wacker Neuson Diaphragm Pump
consists of a gasoline engine, a fuel tank, a handle, a set of wheels, and a
diaphragm pump with ports for fluid suction and discharge. The engine raises and
lowers the diaphragm via a connecting rod. 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.
Intended use 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
■ 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.

■ Do not run the engine near sparks or open flames.
■ Do not touch the engine or muffler while the engine is running or immediately
after it has been turned off.
■ Do not operate a machine when its fuel cap is loose or missing.
■ Do not start the engine if fuel has spilled or a fuel odor is present. Move the
machine away from the spill and wipe the machine dry before starting.
Refueling
safety
When refueling the engine:
