OPERATION
USING THE WATER PUMP
Safe Operating Considerations
Clearances and Air Movement
The water pump must be at least 5 ft. (152 cm) from
structures having combustible walls and/or other
combustible materials. Leave at least 3 ft. (92 cm) all around
water pump including overhead, for adequate cooling,
maintenance and servicing.
DO NOT place water pump where exhaust gas could
accumulate and enter inside or be drawn into a potentially
occupied building. Ensure exhaust gas is kept away from any
windows, doors, ventilation intakes or other openings that
can allow exhaust gas to collect in a confined area
(Figure 8). Prevailing winds and air currents should be taken
into consideration when positioning water pump.
What is “Head”?
Head refers to the height of a column of water that can be
delivered by the discharge of the pump.
Suction Head is the vertical distance between the center of
the pump and the surface of the liquid on the suction side
of the pump. May also be referred to as “suction lift”.The
atmospheric pressure of 14.7 psi at sea level limits suction
head lift to less than approximately 26 feet for any pump.
Discharge Head is the vertical distance between the pump’s
discharge port and the point of discharge, which is the
liquid surface if the hose is submerged or pumping into the
bottom of a tank.
Total Head is the sum of the suction head value plus the
discharge head value.
As water pumping height increases, pump output decreases.
The length, type, and size of the suction and discharge
hoses can also significantly affect pump output.
It is important for the suction operation to be the shorter
part of the total pumping action.This will decrease the
priming time and improve pump performance by increasing
the discharge head.
Suction head is a maximum of 25 feet and discharge head
should be a maximum of 81 feet.Total head can not be
more than 106 feet (Figure 9, next page).
Move Water Pump to Safe
Operating Location
For best pump performance, locate the pump on a flat, level
surface as close as possible to the water to be pumped.
Secure water pump to avoid tipover. Use hoses that are no
longer than necessary.
IMPORTANT: Direct open end of discharge hose away
from home, electrical devices or anything not desired to
get wet.

mixture causing a “flooded” condition, move choke lever to
“Run” ( ) position and pull handle repeatedly until engine
starts.
7. Move choke lever to “Run” ( ) position a short
distance at a time over several seconds in warm
weather or minutes in cold weather. Let engine run
smoothly before each change. Operate with choke in
“Run” position.
IMPORTANT: It may take a few minutes for water pump
to begin pumping water.
Pump output is controlled by adjusting engine speed.
Moving the engine speed lever in the “Fast” direction will
increase pump output, and moving the engine speed lever
in the “Slow” direction will decrease pump output.
• When starting engine, pull cord slowly until resistance is felt

ENGINE TECHNICAL
INFORMATION
These water pumps are powered by a single cylinder,
overhead valve(OHV), air cooled, low emissions engine.
In the State of California, these water pump engines are
certified by the California Air Resources Board to meet
emissions standards for 250 hours. Such certification does
not grant the purchaser, owner or operator of this engine
any additional warranties with respect to the performance
or operational life of this engine.The engine is warranted as
stated elsewhere in this manual.
Power Ratings
The power ratings for an individual engine model are
initially developed by starting with SAE (Society of
Automotive Engineers) code J1940 (Small Engine Power &
Torque Rating Procedure) (Revision 2002-05). Given both
the wide array of products on which our engines are
placed, and the variety of environmental issues applicable to
operating the equipment, it may be that the engine you
have purchased will not develop the rated horsepower
when used in a piece of power equipment (actual “on-site”
power).This difference is due to a variety of factors
including, but not limited to, the following: differences in
altitude, temperature, barometric pressure, humidity, fuel,
engine lubrication, maximum governed engine speed,
individual engine to engine variability, design of the
particular piece of power equipment, the manner in which
the engine is operated, engine run-in to reduce friction and
clean out of combustion chambers, adjustments to the
valves and carburetor, and other factors.The power ratings
may also be adjusted based on comparisons to other
similar engines utilized in similar applications, and will
therefore not necessarily match the values derived using
the foregoing codes.

Oil
Oil Recommendations
NOTE:When adding oil to the engine crankcase, use only
high quality detergent oil rated with API service
classification SF, SG, SH, SJ or higher. DO NOT use special
additives.
1. Choose a viscosity according to the table below:
* The use of multi-viscosity oils (5W-30, 10W-30, etc.) in
temperatures above 40°F (4°C) will result in higher than
normal oil consumption.When using a multi-viscosity oil,
check oil more frequently.
** The use of SAE 30 oil in temperatures below 40°F (4°C)
will result in hard starting and possible engine bore damage
due to inadequate lubrication.
NOTE: Synthetic oil meeting ILSAC GF-2, API certification
mark and API service symbol with “SJ/CF ENERGY
CONSERVING” or higher, is an acceptable oil at all
temperatures. Use of synthetic oil does not alter required
oil change intervals.
Checking Oil Level
Oil level should be checked prior to each use or at least
every 8 hours of operation. Keep oil level maintained.
1. Make sure unit is on a level surface.
2. Remove oil fill cap and wipe clean with cloth.
3. Verify oil is at the point of overflowing at oil fill
opening.
Adding Engine Oil
1. Make sure unit is on a level surface.
2. Check oil level as described in “Checking Oil Level”.
3. If needed, slowly pour oil into oil fill opening to the
point of overflowing at oil fill cap.
Changing Engine Oil
Change the oil after the first 5 hours of operation. Change
oil every 50 hours thereafter. If you are using your water
pump under extremely dirty or dusty conditions, or in
extremely hot weather, change the oil more often.
KEEP OUT OF REACH OF CHILDREN.DON'T
POLLUTE. CONSERVE RESOURCES. RETURN
USED OIL TO COLLECTION CENTERS.

Clean Spark Arrester Screen
The engine exhaust muffler may be equipped a spark
arrester screen. If equipped, inspect and clean the screen
every 50 hours of operation or once each year, whichever
comes first.
If you use your water pump on any forest-covered,brushcovered, or grass-covered unimproved land, it must have a
spark arrester.The spark arrester must be maintained in
good condition by the owner/operator.
If the engine has been running, the muffler will be very hot.
Allow the muffler to cool before servicing the spark
arrester.
• Remove spark arrester screen for cleaning and inspection
(Figure 20).
• Inspect screen and replace if torn, perforated or
otherwise damaged. DO NOT use a defective screen. If
screen is not damaged, clean it with commercial solvent.
• Reattach spark arrester screen to muffler.
NOTE:You can purchase a new spark arrester screen by
calling 1-800-743-4115.
Air Cooling System
Over time debris may accumulate in cylinder cooling fins
and cannot be observed without partial engine disassembly.
For this reason, we recommend you have an authorized
Briggs & Stratton service dealer clean the cooling system
per recommended intervals (see “Maintenance Schedule”
on page 14). Equally important is to keep top of engine free
from debris. See “Cleaning”.
Figure 20 - Spark Arrester
Typical Spark
Arrester Shown
• DO NOT touch hot surfaces and avoid hot exhaust gases.
• Allow equipment to cool before touching.
• The water pump must be at least 5 feet from structures
having combustible walls and/or other combustible materials.
• Keep at least 3 feet of clearance on all sides of water pump
for adequate cooling, maintenance and servicing.
• Reflective exhaust heat may damage fuel tank causing fire.
• Code of Federal Regulation (CFR) Title 36 Parks, Forests, and
Public Property require equipment powered by an internal
combustion engine to have a spark arrester, maintained in
effective working order, complying to USDA Forest service
standard 5100-1C or later revision. In the State of California a
spark arrester is required under section 4442 of the California
Public resources code. Other states may have similar laws.
Running engines produce heat.Temperature of
muffler and nearby areas can reach or exceed
150°F (65°C).
Severe burns can occur on contact.
Combustible debris, such as leaves, grass, brush,
etc. can catch fire.
WARNING
STORAGE
21
STORAGE
The water pump should be started at least once every
seven days and allowed to run at least 30 minutes. If this
cannot be done and you must store the unit for more than
30 days, use the following information as a guide to prepare
it for storage.
Long Term Storage Instructions
It is important to prevent gum deposits from forming in
essential fuel system parts, such as the carburetor, fuel filter,
fuel hose or tank during storage.Also, experience indicates
that alcohol-blended fuels (called gasohol, ethanol or
methanol) can attract moisture, which leads to separation
and formation of acids during storage.Acidic fuel can
damage the fuel system of an engine while in storage.
Fuel Additive:
If adding a fuel additive, fill the fuel tank with fresh fuel. If
only partially filled, air in the tank will promote fuel
deterioration during storage. Engine and fuel can be stored
up to 24 months with additive.
• Add fuel additive following manufacturer’s instructions.
• Run the engine outdoors for 30 seconds to be sure that
treated fuel has replaced the untreated fuel in the
carburetor.
If fuel additive is not used, remove all fuel from tank and
run engine until it stops from lack of fuel.
Change Oil
While engine is still warm, drain oil from crankcase. Refill
with recommended grade.
Oil Cylinder Bore
• Remove spark plug and pour about 1 ounce (30ml) of
clean engine oil into the cylinder.
• Install spark plug and pull starter handle slowly to
distribute oil.
Water Pump
1. Drain water pump as described in “Drain and Flush
Water Pump”.
2. Clean water pump as described in “Cleaning”.
3. Check that openings on water pump are open and
unobstructed.
Other Storage Tips
1. DO NOT store fuel from one season to another.
2. Replace fuel can if it starts to rust. Contaminated fuel
will cause engine problems.
3. If possible, store unit indoors and cover it to give
protection from dust and dirt. BE SURE TO EMPTY
FUEL TANK.
4. Cover unit with a suitable protective cover that does
not retain moisture.
5. Store water pump in clean, dry area.
WHEN STORING FUEL OR EQUIPMENT WITH FUEL
IN TANK
• Store away from furnaces, stoves, water heaters, clothes
dryers or other appliances that have pilot light or other
ignition source because they can ignite fuel vapors.
WHEN DRAINING FUEL
• Turn water pump OFF and let it cool at least 2 minutes
before removing fuel cap. Loosen cap slowly to relieve
pressure in tank.
• Drain fuel tank outdoors.
• Keep fuel away from sparks, open flames, pilot lights, heat, and
other ignition sources.
• DO NOT light a cigarette or smoke.
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or
death.
WARNING
• NEVER pull starter handle with spark plug removed.
Unintentional sparking can result in fire or
electric shock.
WARNING
• DO NOT place a storage cover over a hot water pump.
• Let equipment cool for a sufficient time before placing the
cover on the equipment.
Storage covers can be flammable.
