1.2Machine Description and Intended Use
This machine is a centrifugal trash pump. The Wacker Neuson Trash
Pump consists of a tubular steel frame surrounding a gasoline or
diesel 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

4.2Recommended Fuel
(Wacker Neuson / Honda)
The engine requires regular grade unleaded gasoline. Use only fresh,
clean gasoline. Gasoline containing water or dirt will damage fuel
system. Consult engine owner’s manual for complete fuel
specifications.
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 / Provinces require this information to be posted on the fuel
pump.
The following are Wacker Neuson approved percentages 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.
4.3Recommended Fuel (Hatz)
The engine requires No. 2 diesel fuel. Use only fresh, clean fuel. Fuel
containing water or dirt will damage the fuel system. Consult the
engine owner’s manual for complete fuel specifications.

4.13Hoses and Clamps
See Graphic: wc_gr000021
Suction hoses (a) must be rigid enough not to collapse when pump is
operating.
Discharge hoses (b) are usually thin-walled collapsible hoses. Rigid
hoses similar to those used as suction hoses may also be used as
discharge hoses.
Note: Suction and discharge hoses are available from Wacker
Neuson. Contact your nearest dealer for more information.
Two clamps (c) are recommended for connection of suction hoses to
inlet coupling.
Note: This connection is important. Even a small air leak on the suction
side of pump will prevent the pump from priming.

or individual; however, warranty repairs must be performed by a
dealer/service center authorized by WACKER NEUSON. The use of
service parts that are not equivalent in performance and durability to
authorized parts may impair the effectiveness of the emission control
system and may have a bearing on the outcome of a warranty claim.

5.13Adjusting the Impeller Clearance
See Graphic: wc_gr000035
If it is necessary to replace the impeller or the volute insert, be sure
clearance between impeller and insert is adjusted correctly. The
impeller (a) should be as close to the insert (b) as possible without
rubbing against it. Clearance is adjusted by adding or removing shims
(c).
5.13.1Remove spark plug (on units with Hatz engine, place speed control
lever in STOP position) so that engine will not start.
5.13.2Check clearance between impeller and insert by slowly pulling starter
rope to turn impeller.
If starter rope is difficult to pull, or rubbing is heard from inside pump,
the impeller and insert are too close to each other. Remove a shim
from behind insert and check again for rubbing. Continue removing
shims until impeller turns easily.
Note: It is important not to remove too many shims or the clearance
between the impeller and insert will become too wide and pump
performance will be reduced.
As the impeller wears down, additional shims may be required to
maintain the clearance between the impeller and insert.
