Description
Earthquake Pumps are general use centrifugal
water pumps.
Safety Guidelines
This manual contains information that is very
important to know and understand. This infor-
mation is provided for SAFETY and to PREVENT
EQUIPMENT PROBLEMS. To help recognize this
information, observe the following symbols.
DANGER
Danger indicates an imminently hazard-
ous situation which, if not avoided, will
result in death or serious injury.
WARNING
Warning indicates a potentially hazardous
situation which, if not avoided, could result
in death or serious injury.
CAUTION
Caution indicates a potentially hazardous
situation which, if not avoided, may result
in minor or moderate injury.
NOTICE
Notice indicates important information,
that if not followed, may cause damage to
equipment.
GENERAL SAFETY INFORMATION
1. Know the pump application, limitations, and
potential hazards. Read these rules and the
instructions carefully. Failure to follow them could
cause serious bodily injury and/or property dam-
age.
DANGER
Never run engine in an enclosed area. Ex-
haust gases contain deadly poisonous car-
bon monoxide, which has no odor or taste.
WARNING
Do not use to pump flammable or explo-
sive fluids such as gasoline, fuel oil, kero-
sene, etc. Do not use in flammable and/or
explosive atmospheres. Pump should only
be used to pump water. Failure to follow
this warning can result in personal injury
and/or property damage.
2. Observe all safety precautions for the handling
of the fuel.
WARNING
Do not refuel a hot engine. Fuel spilled on
a hot engine could result in a fire or explo-
sion. Do not refuel a running engine.
3. Pump should be located and should rest on a
level solid foundation. Do not suspend pump
by means of the discharge pipe.
NOTICE
Be sure pump is on secure footing so it
doesn't fall over.
4. Do not use torches or apply excessive heat, fire
or flames to this pump as an explosion may
result.

5. Before working on the unit, insulate the wire
from the spark plug, disconnect the spark plug
wire and mount it on the grounding clip.
NOTICE
Complete pump and piping system MUST
be protected against below freezing tem-
perature. Failure to do so could cause
serious damage and voids the warranty.
6. Do not run pump dry. Water is required to
lubricate the shaft seal.
7. Pumping chemicals or corrosive liquids with
this pump may shorten the life of the pump
and may be hazardous to the operator.
8. Personal Safety:
a. Wear safety glasses at all times when work-
ing with pumps.
b. Keep work area clean, uncluttered and
properly lighted; replace all unused tools and
equipment.
c. Keep visitors at a safe distance from the
work area.
9. Always use a suction strainer with this pump to
filter large material.
INSTALLATION
This pump is designed to be self-priming when
installed and operated as specified below.
1. The pump should be placed as close as pos-
sible 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 (Fig-
ure 1).
2. Suction hose and fitting must be airtight.
NOTICE
An air leak in the suction line may prevent
priming of the pump. Use of thread seal-
ant is recommended.
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 filter abrasive
material
5. The discharge hose and fitting should not leak.
A leak in the discharge hose will allow water to
spray out. Water spray could be hazardous.
6. Keep all pipes and hose lines as short and
straight as possible. Long lengths and curves
in the pipes and hose lines will reduce the
pressure the pump develops.

7. Fill the engine crankcase with oil. Refer to the
engine operating manual for the specific grade
of oil and amount required.
8. Fill the engine fuel tank with gasoline. Refer to
the engine operating manual for specific gaso-
line type that is most efficient for this engine.
9. Add water to the priming port on the pump
(See Figure 2). 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.
10. Turn fuel valve to 'ON' position.
11. Move choke lever to 'CHOKE' position.
12. Move throttle lever to 'START' position.
13. Pull engine crank until engine starts. Once
engine starts, move choke lever to 'RUN' posi-
tion.
14. The pump will 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.
WARNING
Support pump and piping when assem-
bling 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.
All suction connections must be airtight. If the
pump won't prime, check for leaks in the suction
piping or fittings. If flexible suction hose is used
instead of pipe, use reinforced hose with a two
inch inner diameter. Non-reinforced flexible 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 be-
come 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-
five feet.
MAINTENANCE
Always shut off the engine, allow the engine to
cool, and remove the spark plug before perform-
ing 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
off sensor. The engine will shut down and will not
restart if the oil level becomes low.
