2.2 Operating Safety
Familiarity and proper training are required for the safe operation of
equipment. Equipment 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 equipment before
being allowed to operate the machine.
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 leave machine running unattended.
2.2.5 NEVER operate this machine in applications for which it is not
intended.
2.2.6 NEVER open the priming plug when the pump is hot. Never 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.
2.2.7 NEVER position the pump on a loose, uneven, or unstable surface
where it can tip, roll, slide or fall! The pump must be secure before
operating. Position the pump on a firm, flat surface; adjust the trailer
jacks to be sure the pump is level and supported firmly.
2.2.8 NEVER open the pump housing cover while the pump is operating or
start the pump with the cover off. The rotating impeller inside the pump
can cut or sever objects caught in it.
2.2.9 NEVER block or restrict flow from the inlet line or the discharge line.
Remove kinks from the discharge line before starting the pump.
Operation with a blocked inlet line or discharge line can cause water
inside the pump to overheat.
2.2.10 NEVER reach into or insert anything into the pump while the engine is
on! The impeller inside the pump housing is turning at all times while
the engine is running.
2.2.11 DO NOT allow anyone to stand in front of the discharge port when
starting the engine or while priming the pump! The sudden out-rush of
water could push or knock a person down.
WARNING

Safety Information PT 6 /...
wc_si000098gb.fm 6
2.2.12 ALWAYS make sure the hose connections on the pump are tight. A
loose connection could cause water to spray or result in a hose falling
off the pump while it is in operation.
2.2.13 ALWAYS make sure the water stream from the pump discharge is not
directed in such a way so as to cause erosion to the surrounding
ground or damage or weakening of nearby structures!
2.3 Operator Safety While Using Internal Combustion Engines
2.3.1 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. Exhaust gas from the engine
contains poisonous carbon monoxide gas; exposure to carbon
monoxide can cause loss of consciousness and may lead to death.
2.3.2 DO NOT smoke while operating the machine.
2.3.3 DO NOT smoke when refueling the engine.
2.3.4 DO NOT refuel a hot or running engine.
2.3.5 DO NOT refuel the engine near an open flame.
2.3.6 ALWAYS refill the fuel tank in a well-ventilated area.
2.3.7 ALWAYS replace the fuel tank cap after refueling.
2.3.8 ALWAYS check the fuel lines and the fuel tank for leaks and cracks
before starting the engine. Do not run the machine if fuel leaks are
present or the fuel lines are loose.
2.3.9 ALWAYS keep the area around a hot exhaust pipe free of debris to
reduce the chance of an accidental fire.
2.4 Service Safety
Poorly maintained equipment can become a safety hazard! In order
for the equipment 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 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.
2.4.3 DO NOT attempt to clean or service the machine while it is running.
2.4.4 DO NOT operate the machine without an air cleaner.
2.4.5 ALWAYS replace worn or damaged components with spare parts
designed and recommended by Wacker Corporation.
WARNING

PT 6 /... Safety Information
wc_si000098gb.fm 7
2.4.6 ALWAYS keep the machine clean and labels legible. Replace all
missing and hard-to-read labels. Labels provide important operating
instructions and warn of dangers and hazards.
2.4.7 ALWAYS replace the safety devices and guards after repairs and
maintenance.
2.4.8 ALWAYS check all external fasteners at regular intervals.
2.4.9 ALWAYS remain aware of moving parts and keep hands, feet, and
loose clothing away from the moving parts of the equipment.
2.5 Towing Safety
Towing a large trailer requires special care. Both the trailer and vehicle
must be in good condition and securely fastened to each other to
reduce the possibility of an accident.
2.5.1 ALWAYS check that the hitch and coupling on the vehicle are rated
equal to, or greater than, the trailer's “gross vehicle weight rating”
(GVWR).
2.5.2 ALWAYS inspect the hitch and coupling for wear or damage. DO NOT
tow the trailer using defective parts.
2.5.3 ALWAYS make sure the coupling is securely fastened to the vehicle.
2.5.4 ALWAYS check the tires on the trailer for tread wear, inflation, and
condition. Replace worn tires.
2.5.5 ALWAYS connect the safety chains.
2.5.6 ALWAYS connect the breakaway cable safety hook to the bumper or
rear of the vehicle. DO NOT attach it to the hitch.
2.5.7 ALWAYS test the surge brakes on the trailer and the brakes on the
vehicle that will be used for towing.
2.5.8 ALWAYS make sure directional and trailer lights are connected and
working properly.
2.5.9 ALWAYS check that the lug nuts holding the wheels are tight and that
none are missing.

2.6 Reporting Trailer Safety Defects
If you believe your trailer has a defect which could cause a crash or
could cause injury or death, you should immediately inform the
National Highway Traffic Safety Administration (NHTSA) in addition to
notifying Wacker Corporation.
If NHTSA receives similar complaints, it may open an investigation;
and if it finds that a safety defect exists in a group of vehicles, it may
order a recall and remedy campaign. However, NHTSA cannot
become involved in individual problems between you, your dealer, or
Wacker Corporation.
To contact NHTSA, you may either contact the Auto Safety Hotline toll-
free at 1-800-424-9393 (or 366-0129 in Washington DC area),
www.nhtsa.com, or write to NHTSA, U.S. Department of
Transportation, 400 7th Street SW, (NSA-11), Washington, DC 20590.
You can also obtain other information about motor vehicle safety from
the Auto Safety Hotline.
