1.1 Operating Safety
Notice: State Health Safety Codes and Public Resources Codes
specify that in certain locations spark arresters be used on internal
combustion engines that use hydrocarbon fuels. A spark arrester is a
device designed to prevent accidental discharge of sparks or flames
from the engine exhaust. Spark arresters are qualified and rated by
the United States Forest Service for this purpose.
In order to comply with local laws regarding spark arresters, consult
the engine distributor or the local Health and Safety Administrator.
Familiarity and proper training are required for the safe operation of the
machine. Machines operated improperly or by untrained personnel
can be dangerous. Read the operating instructions contained in both
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.
1.1.1 Do not allow anyone to operate this equipment without proper training.
People operating this equipment must be familiar with the risks and
hazards associated with it.
1.1.2 Do not use accessories or attachments that are not recommended by
Wacker Neuson. Damage to equipment and injury to the user may
result.
1.1.3 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.
1.1.4 Do not pump volatile, flammable, or low flash point fluids. These fluids
could ignite or explode.
1.1.5 Do not pump corrosive chemicals or water containing toxic
substances. These fluids could create serious health and
environmental hazards. Contact local authorities for assistance.
1.1.6 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 radiator 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.
1.1.7 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.
1.1.8 Do not block or restrict flow from inlet line or discharge line. Remove
kinks from discharge line before starting pump. Operation with a
blocked inlet line or discharge line can cause water inside pump to
overheat.
WARNING

PT 2/3 /... Safety Information

1.1.9 Be sure operator is familiar with proper safety precautions and
operation techniques before using machine.
1.1.10 Read, understand, and follow procedures in the Operator’s Manual
before attempting to operate the machine.
1.1.11 Be sure the machine is on a firm, level surface and will not tip, roll,
slide, or fall while operating.
1.1.12 Close fuel valve on engines equipped with one when machine is not
being operated.
1.1.13 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.
1.2 Operator Safety while using Internal Combustion Engines
Internal combustion engines present special hazards during operation
and fueling. Read and follow the warning instructions in the engine
owner’s manual and the safety guidelines below. Failure to follow the
warnings and safety standards could result in severe injury or death.
1.2.1 Do not run the machine indoors or in an enclosed area such as a deep
trench unless adequate ventilation, through such items as exhaust
fans or hoses, is provided. Engine exhaust contains carbon monoxide.
This is a poison you cannot see or smell. Exposure to carbon
monoxide can cause loss of consciousness and CAN KILL YOU IN
MINUTES.
1.2.2 Do not smoke while operating the machine.
1.2.3 Do not smoke when refueling the engine.
1.2.4 Do not refuel a hot or running engine.
1.2.5 Do not refuel the engine near an open flame.
1.2.6 Do not run the engine near open flames.
1.2.7 Do not test for spark on gasoline-powered engines if the engine is
flooded or the smell of gasoline is present. A stray spark could ignite
the fumes.
1.2.8 NEVER operate pump in enclosed or confined area.
1.2.9 Refill the fuel tank in a well-ventilated area.
1.2.10 Replace the fuel tank cap after refueling.

1.3 Service Safety
A poorly maintained machine can become a safety hazard! In order
for the machine to operate safely and properly over a long period of
time, periodic maintenance and occasional repairs are necessary.
1.3.1 Do not attempt to clean or service the machine while it is running.
Rotating parts can cause severe injury.
1.3.2 Do not crank a flooded engine with the spark plug removed on
gasoline-powered engines. Fuel trapped in the cylinder will squirt out
the spark plug opening.
1.3.3 Keep the area around the muffler free of debris such as leaves, paper,
cartons, etc. A hot muffler could ignite the debris and start a fire.
1.3.4 Replace worn or damaged components with spare parts designed and
recommended by Wacker Neuson Corporation.
1.3.5 Disconnect the spark plug on machines equipped with gasoline
engines, before servicing, to avoid accidental start-up.
1.3.6 Do not use gasoline or other types of fuels or flammable solvents to
clean parts, especially in enclosed areas. Fumes from fuels and
solvents can become explosive.
1.3.7 Handle impeller carefully. The impeller can develop sharp edges which
can cut.

2.4 Before Starting
See Graphic: wc_gr000013
2.4.1 Read safety instructions at the beginning of this Operator’s Manual.
2.4.2 Place pump as near to water as possible, on a firm, flat, level surface.
2.4.3 To prime pump, remove prime plug (a) and fill pump housing with
water. If the pump housing is not filled with water before starting, it will
not begin pumping.
Do not open priming plug, discharge plug, or loosen hose fittings if
pump is hot! Water or vapor inside pump may be under pressure.
2.4.4 Check for leaks between pump and engine. If water is leaking, the seal
inside pump is worn or damaged. Continued operation may cause
water damage to engine.
2.4.5 Check that hoses are securely attached to pump. Suction hose (b)
must not have any air leaks. Tighten hose clamps (c) and couplings
(d). Check that discharge hose (e) is not restricted. Lay hose out as
straight as possible. Remove any twists or sharp bends from hose
which may block the flow of water.
2.4.6 Make sure suction strainer (f) is clean and securely attached to end of
hose. The strainer is designed to protect the pump by preventing large
objects from being pulled into the pump.
NOTICE: Strainer should be positioned so it will remain completely
under water. Running the pump with the strainer above water for long
periods can damage the pump.
2.4.7 Check fuel level, engine oil level, and condition of air cleaner.
