2. Safety Information
This manual contains DANGER, WARNING, CAUTION, NOTICE and
NOTE callouts which must be followed to reduce the possibility of
personal injury, damage to the equipment, or improper service.
This is the safety alert symbol. It is used to alert you to potential
personal injury hazards. Obey all safety messages that follow this
symbol to avoid possible injury or death.
DANGER indicates a hazardous situation which, if not avoided, will
result in death or serious injury.
WARNING indicates a hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTION indicates a hazardous situation which, if not avoided, could
result in minor or moderate injury.
NOTICE:Used without the safety alert symbol, NOTICE indicates a
hazardous situation which, if not avoided, could result in property
damage.
Note: Contains additional information important to a procedure.
2.1 Laws Pertaining to Spark Arresters
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.

Safety Information PD 2A/3A

2.2 Operating Safety
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.
2.2.1 NEVER allow anyone to operate this equipment without proper
training. People operating this equipment must be familiar with the
risks and hazards associated with it.
2.2.2 NEVER 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.
2.2.3 NEVER use accessories or attachments that are not recommended by
Wacker. Damage to equipment and injury to the user may result.
2.2.4 NEVER pump volatile, flammable or low flash point fluids. These fluids
could ignite or explode.
2.2.5 NEVER pump corrosive chemicals or water containing toxic
substances. These fluids could create serious health and
environmental hazards. Contact local authorities for assistance.
2.2.6 ALWAYS read, understand, and follow procedures in the Operator’s
Manual before attempting to operate the machine.
2.2.7 ALWAYS be sure operator is familiar with proper safety precautions
and operation techniques before using machine.
2.2.8 ALWAYS be sure the rammer will not tip over, roll, slide, or fall when
not being operated.
2.2.9 ALWAYS close fuel valve on engines equipped with one when
machine is not being operated.
2.2.10 ALWAYS 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.

2.3 Operator Safety while using Internal Combustion Engines
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.
2.3.1 DO NOT smoke while operating the machine.
2.3.2 DO NOT smoke when refueling the engine.
2.3.3 DO NOT refuel a hot or running engine.
2.3.4 DO NOT refuel the engine near an open flame.
2.3.5 DO NOT spill fuel when refueling the engine.
2.3.6 DO NOT run the engine near open flames.
2.3.7 ALWAYS refill the fuel tank in a well-ventilated area.
2.3.8 ALWAYS replace the fuel tank cap after refueling.
2.4 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.
2.4.1 DO NOT attempt to clean or service the machine while it is running.
Rotating parts can cause severe injury.
2.4.2 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.
2.4.3 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.
2.4.4 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.
2.4.5 ALWAYS operate the machine with all safety devices and guards in
place and in working order.
2.4.6 ALWAYS 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.
2.4.7 ALWAYS replace worn or damaged components with spare parts
designed and recommended by Wacker Corporation.
2.4.8 ALWAYS disconnect the spark plug on machines equipped with
gasoline engines, before servicing, to avoid accidental start-up.

The required sound specification, Paragraph 1.7.4.f of 89/392/EEC
Machinery Directive, is:
• the guaranteed sound power level (LWA) = 96 dB(A).
• the sound pressure level at operator’s location (LpA) = 82 dB(A).

Operation PD 2A/3A
wc_tx000228gb.fm 18
4. Operation
4.1 Application
This pump is intended for removing clean water or water containing a
large amount of debris and suspended solids. The model PD 2A can
pump water containing solids up to 30 mm (1.25 in.) diameter. The
model PD 3A can pump water containing solids up to 45 mm (1.75 in.)
in diameter.
Diaphragm pumps are ideal for pumping mud, slurries and seepage.
Typical applications include dewatering of trenches, sewers, pipelines,
septic tanks, holding tanks, farm ponds, fields and excavations where
a large amount of solids may be present in the water.
4.2 Recommended Fuel
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.

PD 2A/3A Operation
wc_tx000228gb.fm 19
4.3 Transporting the Machine
Fire hazard. Spilled fuel can ignite and cause severe burns. Lift and
transport the machine in an upright position.
When lifting and transporting this machine:
• Close the fuel valve.
• Lift and transport it in an upright position.
• Use the lifting hook (a) to lift the machine.
• Use lifting equipment capable of lifting at least 70 kg (150 lbs.).
• Use the lifting hook, rear tie-down bar (b), and the handle (c) to
secure the machine to the transport vehicle.
• Do not use the wheels or the axle as tie-down points.

Operation PD 2A/3A
wc_tx000228gb.fm 20
4.4 Priming Pump
See Graphic: wc_gr001064
Diaphragm pumps are self priming and seldom need to have water
added to them before starting. However, if the pump has not been
used for several weeks and the rubber valves inside it are dry, adding
water through the surge chamber (f) will help the valves seal and
shorten the amount of time required for the pump to prime.
4.5 Before Starting
See Graphic: wc_gr001064
4.5.1 Read safety instructions at the beginning of manual.
4.5.2 Place pump as near to water as possible, on a firm, flat, level surface.
4.5.3 Check that hoses are securely attached to pump. Suction hose (c)
must not have any air leaks. Check that all hose clamps (b) and
couplings (a) are tight. Check that cap on surge chamber (f) is tight.
4.5.4 Check that discharge hose (e) is not blocked. Lay hose out as straight
as possible. Remove any twists or sharp bends from hose which may
block the flow of water.
Note: Operating the pump with any part of the discharge line
positioned higher than 7.5 m (25 ft.) above the pump can cause
backflow into the pump and damage pump components.
4.5.5 Make sure suction strainer (d) 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.
Position strainer so it will remain under water as water level drops.
4.5.6 Check fuel level, engine oil level, and condition of air cleaner.
