ENGINE SAFETY PRECAUTIONS
Warning Carbon Monoxide Poisoning
Engines give off carbon monoxide, an odorless, colorless,
poisonous gas. Carbon monoxide may be present even if you do
not smell or see any engine exhaust. Breathing carbon monoxide
can cause nausea, fainting or death, in addition to drowsiness,
dizziness and confusion. If you experience any of these
symptoms, seek fresh air and medical attention immediately.
If your product comes with a separate engine manual, be
sure to read and follow all safety and warning precautions
outlined there, in addition to any in this manual.
Preventing Carbon Monoxide Poisoning
• Always start and run engine outdoors. Do not start or run
engine in an enclosed area, even if doors or windows are open.
• Never try to ventilate engine exhaust indoors. Carbon
monoxide can reach dangerous levels very quickly.
• Never run engine outdoors where exhaust fumes may be
pulled into a building.
• Never run engine outdoors in a poorly ventilated area where
the exhaust fumes may be trapped and not easily taken
away. (Examples include: in a large hole or areas where hills
surround your working area.)
• Never run engine in an enclosed or partially enclosed area.
(Examples include: buildings that are enclosed on one or
more sides, under tents, car ports or basements.)
• Always run the engine with the exhaust and muer pointed
in the direction away from the operator.
• Always keep the throttle in the “slow” position when not in use.
• Never point the exhaust muer towards anyone. People
should always be many feet away from the operation of the
engine and its attachments.
• Do not change the engine governor settings or over-speed
the engine.
Gasoline Fires and Handling Fuel Safely
Use extra care in handling gasoline and other fuels. They are
ammable and vapors are explosive.
• When storing extra fuel be sure that it is in an appropriate
container and away from any re hazards.
• Prevent re and explosion caused by static electric discharge.
Use only nonmetal, portable fuel containers approved by the
Underwriter’s Laboratory (U.L.) or the American Society for
Testing & Materials (ASTM).
• Always ll fuel tank outside in a well ventilated area. Never
fill your fuel tank with fuel indoors. (Examples include:
basement, garage, barn, shed, house, porch, etc.) Never
ll tank near appliances with pilot lights, heaters, or other
ignition sources. If the fuel has to be drained, this should

INSTALLATION
Operator’s Manual
WP6520 and WP6530 Water Pumps
WARNING
SUPPORT PUMP AND PIPING WHEN ASSEMBLING
AND AFTER INSTALLATION. FAILURE TO DO SO MAY
CAUSE PIPING TO BREAK, PUMP TO FAIL, ETC; ALL OF
WHICH CAN RESULT IN PROPERTY DAMAGE AND/OR
PERSONAL INJURY.
This pump is designed to be self-priming when installed and
operated as specied below.
1. The pump should be placed as close as possible to the liquid
being pumped. A pump with 20 foot suction lift will not
remove water as quickly as a pump with 5 foot suction lift.
SEE FIGURE 2.
2. Suction hose and tting must be airtight.
Suction lines must be reinforced hose or rigid pipe. Non-reinforced hose will collapse due to the suction created by the
pump and prevent pump from operating.
3. A check valve must be used in the suction line to maintain
the self-priming capability. If no check valve is used the
pump will need to be primed at the start of each operation.
For best operation, the check valve should be installed at
the intake of the suction line.
4. A suction strainer is required to lter abrasive material
5. The discharge hose and tting should not leak. A leak in the
discharge hose will allow water to spray out. Water spray
could be hazardous.
CAUTION
NEVER ADD FUEL WHEN ENGINE IS RUNNING OR HOT
FROM OPERATION. NEVER FILL THE TANK INDOORS.
DO NOT SMOKE WHEN FILLING FUEL TANK.
NEVER FILL FUEL TANK COMPLETELY. FILL TANK TO 1/2"
BELOW BOTTOM OF FILLER NECK TO PROVIDE SPACE
FOR FUEL EXPANSION. WIPE ANY FUEL SPILLAGE FROM
ENGINE AND EQUIPMENT BEFORE STARTING ENGINE.
NEVER RUN ENGINE INDOORS OR IN ENCLOSED, POORLY
VENTILATED AREAS. ENGINE EXHAUST CONTAINS
CARBON MONOXIDE, AN ODORLESS AND DEADLY GAS.
KEEP HANDS, FEET, HAIR AND LOOSE CLOTHING AWAY
FROM ANY MOVING PARTS ON ENGINE AND EQUIPMENT.
TEMPERATURE OF MUFFLER AND NEARBY AREAS MAY
EXCEED 150° F. AVOID THESE AREAS.
NEVER SYPHON FUEL BY MOUTH.
IMPORTANT
AN AIR LEAK IN THE SUCTION LINE MAY PREVENT
PRIMING OF THE PUMP USE OF THREAD SEALANT IS
RECOMMENDED.
6. Keep all pipes and hose lines as short and straight as pos-
sible. Long lengths and curves in the pipes and hose lines
will reduce the pressure the pump develops.

OPERATION
1. Fill the engine crankcase with oil. Refer to the engine operat-
ing manual for the specic grade of oil and amount required.
2. Fill the engine fuel tank with gasoline. Refer to the engine
operating manual for specic gasoline type that is most efcient for this engine.
3. Add water to the priming port on the pump SEE FIGURE 3.
Continue adding water until the water level is approximately
3 inches from the top. Install the priming plug. The water in
the pump will create the suction that primes the pump.
4. Turn fuel valve to ‘ON’ position.
5. Move choke lever to ‘CHOKE’ position.
6. Move throttle lever to ‘START’ position.
7. Pull engine crank until engine starts. Once engine starts,
move choke lever to ‘RUN’ position.
NOTE: The pump may take several minutes to prime.
PIPING
Always place the pump as close as possible to the liquid being
pumped. Keep all pipe and hose lines as short and straight as possible.
All suction connections must be airtight. If the pump won’t
prime, check for leaks in the suction piping or ttings. If exible
suction hose is used instead of pipe, use reinforced hose with a
two inch inner diameter. Non-reinforced exible hose may collapse from the vacuum created as the pump primes.
Always use a strainer at the end of the suction pipe or hose. Position strainer so it doesn’t become clogged with stones or debris.
A suction line check valve next to strainer is recommended.
Do not use this pump for suction lifts over twenty-ve feet.

MAINTENANCE AND STORAGE
STEPS FOR WORKING ON EQUIPMENT
1. Turn o engine switch.
2. Disconnect the spark plug wire from the spark plug.
3. Securely place the disconnected spark plug wire away from
the spark plug and any metal parts. This must always be done
or arcing may occur between spark plug wire and metal parts.
4. Replace or repair the part on the pump.
5. Check all parts that were repaired, or removed during repair,
that they are secure and t correctly.
NOTE: All repair parts must come from the factory. Never replace parts that are not specically designed for the pump.
6. Reconnect the spark plug wire.
PUMP MAINTENANCE
Always shut o the engine, allow the engine to cool, and remove the spark plug before performing any maintenance.
During freezing weather, open the drain port and allow all the
water in the pump to drain. This will prevent damage to the
pump when the water freezes. If the pump will be stored for a
month or more, drain the water from the pump and follow the
engine manufacturer’s recommendations for long-term storage.
The Viper engine is equipped with a low oil shut o sensor. The engine will shut down and will not restart if the oil level becomes low.
ENGINE MAINTENANCE
Good maintenance is essential for safe, economical, and troublefree operation. It will also help reduce air pollution.
Please read the maintenance schedule in the accompanying
engine manual and observe these recommendations to extend
the life of your pump. The engine manual also outlines routine
inspection procedures and simple maintenance procedures
using basic hand tools. Service tasks that are more dicult, or
require special tools, are best handled by professionals and are
normally performed by a technician or other qualied mechanic.
Maintenance, replacement or repair of the emissions control
devices and systems may be performed by any non-road
engine repair establishment or individuals. However, items
must be serviced by an authorized dealer to obtain "no charge"
emissions control service.
If you operate your engine under unusual conditions, such as
sustained high-load or high-temperature operation, or use in
unusually wet or dusty conditions, consult your servicing dealer
for recommendations applicable to your individual needs and use.
