ASSEMBLY

Type of Fuel

1. Always use clean, fresh, unleaded gasoline with a minimum of 87 octane/87 AKI (91 RON). Do Not mix oil with fuel. Do not modify the engine fuel system or carburetor to run on alternative fuels.

NOTE: Fuel with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether), is acceptable.

IMPORTANT: Use of any fuel other than those approved above will void warranty. Some areas require that fuel pumps be marked if the fuel contains alcohols or ethers. If you are not sure if your fuel contains alcohol or ethers that are different than those approved above, then check with the service station operator.

2. Clean area around fuel fill cap, remove cap.

3. Using a fuel funnel (optional), slowly add unleaded gasoline until fuel level is approximately 1” below top of fuel tank neck to allow for fuel expansion (Figure 2). Be careful not to overfill.

4. Install fuel cap and let any spilled fuel evaporate before starting engine.

To avoid engine performance issues, the fuel system should be treated with a fuel preserver or emptied before storage of 30 days or longer. To protect the fuel system from gum formation, use Briggs & Stratton FRESH START™ fuel stabilizer plus. If fuel preserver is not used, drain the fuel tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See “Storage” on page 18 for additional information.

NEVER use engine or carburetor cleaner products in the fuel tank as permanent damage may occur.

High-altitude use

Operation at high altitude (over 5,000 feet), may require a high-altitude carburetor jet kit to improve performance and decrease fuel consumption. See your local authorized Briggs & Stratton dealer for more information.

OPERATION

USING THE WATER PUMP

Safe Operating Considerations

Clearances and Air Movement

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 10). 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 23 feet (7 m) and discharge head should be a maximum of 92 feet (28 m). Total head can not be more than 115 feet (35 m) (Figure 11, 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.

SPECIFICATIONS

ENGINE TECHNICAL

INFORMATION

This is a single cylinder, air cooled engine. It is a 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 50 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.

MAINTENANCE

General Recommendations

Regular maintenance will improve the performance and extend the life of the water pump. We recommend you use an authorized Briggs & Stratton service dealer for all maintenance and service. Use only genuine Briggs & Stratton parts.

The water pump’s warranty does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain water pump as instructed in this manual.

All service and adjustments should be made at least once each season. Follow the requirements in the “Maintenance Schedule” chart above.

NOTE: Once a year you should clean or replace the spark plug and replace the air filter. A new spark plug and clean air filter assure proper fuel-air mixture and help your engine run better and last longer.

Emissions Control

Maintenance, replacement or repair of the emissions control devices and systems may be performed by any non-road engine repair establishment or individual. See emissions control system warranty, elsewhere in this manual.

Maintenance

Maintenance consists of keeping the water pump clean. Store the unit in a clean dry environment where it will not be exposed to excessive dust, dirt, moisture or any corrosive vapors. Cooling air slots in the water pumps engine must not become clogged with dirt, leaves or any other foreign material.

NOTE: DO NOT use a garden hose to clean water pumps engine. Water can enter engine fuel system and cause problems.

Cleaning

Daily or before use, look around and underneath water pump for signs of oil or fuel leaks. Clean accumulated debris from inside and outside water pump. Keep linkage, spring and other engine controls clean. Keep area around and behind muffler free from any combustible debris. Inspect cooling air slots and opening on water pump. These openings must be kept clean and unobstructed.

Engine parts should be kept clean to reduce the risk of overheating and ignition of accumulated debris.

• Use a damp cloth to wipe exterior surfaces clean.

• Use a soft bristle brush to loosen caked on dirt or oil.

• Use a vacuum cleaner to pick up loose dirt and debris.

MAINTENANCE SCHEDULE

Follow the hourly or calendar intervals, whichever occurs first. More frequent service is required when operating in adverse conditions noted below.

Change oil after the first (4) operating hours and every 8 hours or every year, whichever occurs first, thereafter. Change oil every 4 hours when operating under heavy loads or in high temperatures. Clean more often under dusty conditions or when airborne debris is present. Replace air cleaner if very dirty.

Oil

Oil Recommendations NOTE: When adding oil to the engine crankcase, use

only high quality detergent oil classified “For Service SF, SG, SH, SJ” or higher. DO NOT use special additives.

1. Choose a viscosity according to the following table:

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.

SAE 30: 40 °F and higher (5 °C and higher) is good for all purpose use above 40°F, use below 40°F will cause hard starting.

10W-30: 0 to 100 °F (-18 to 38 °C) is better for varying temperature conditions.This grade of oil improves cold weather starting, but may increase oil consumption at 80°F (27°C) or higher. *Check oil level frequently at higher temperatures.

Synthetic 5W-30: -20 to 120 °F (-30 to 40 °C) provides the best protection at all temperatures as well as improved starting with less oil consumption.

5W-30: 40 °F and below (5 °C and below) is recommended for winter use, and works best in cold conditions.

MAINTENANCE

Service Air Cleaner

Your engine will not run properly and may be damaged if you run it with a dirty air cleaner.

Service the air cleaner every 8 hours of operation or once each year, whichever comes first. Service more often if operating under dirty or dusty conditions.

Check and clean the intake chamber for dirt. If the foam air cleaner is dirty and worn, replace with new air cleaner.

To service the air cleaner, follow these steps:

1. Push cover tab to release cover, then pull cover away from the engine (Figure 23).

2. Carefully remove foam air cleaner.

3. Wash foam air cleaner in liquid detergent and water. Squeeze dry in a clean cloth.

4. Dip foam air cleaner in engine oil and squeeze in a clean cloth to remove excess oil.

NOTE: Engine will smoke if too much oil is left on air cleaner.

5. Reinstall clean air cleaner.

6. Push cover closed to lock tab into base.

Service Spark Plug

Change the spark plug every 50 hours of operation or once each year, whichever comes first. This will help your engine to start easier and run better.

1. Clean area around spark plug.

2. Remove and inspect spark plug.

3. Check electrode gap with wire feeler gauge and set spark plug gap to 0.025 inch (0.64mm) if necessary (Figure 24).

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.

Protect Fuel System

Fuel Stabilizer:

Follow these instructions if storing fuel more than 30 days. To protect the fuel system from gum formation, use

Briggs & Stratton FRESH START™ fuel stabilizer plus. If fuel stabilizer is used, you do not need to drain fuel

prior to storage.

• Run engine outdoors for several minutes to be sure treated fuel has replaced untreated fuel in carburetor.

If fuel preserver is not used, then always 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. See “Changing Oil” on page 16.

Oil Cylinder Bore

• Remove spark plug and pour about 1 teaspoon (5 ml) of clean engine oil into the cylinder.

• Install spark plug and pull starter handle slowly 8-10 times 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

unless it has been treated as described in “Protect Fuel System”.

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.

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.
