OPERATION
PUMP PLACEMENT
SUCTIONHEAD
DISCHARGEHEAD
TTOOTTAALL HHEEAADD
For best pump performance, place the pump near the water level, anduse hoses that are no longer than necessary. That will enable thepump to produce the greatest output with the least self-priming time.
As head (pumping height) increases, pump output decreases. Thelength, type, and size of the suction and discharge hoses can alsosignificantly affect pump output.
Discharge head capability is always greater than suction headcapability, so it is important for suction head to be the shorter part oftotal head.
Minimizing suction head (placing the pump near the water level) isalso very important for reducing self-priming time. Self-priming timeis the time it takes the pump to bring water the distance of the suctionhead during initial operation.

Securely tighten the hose connector on the pump suction port.
Install the strainer (provided with the pump) on the other end of thesuction hose, and secure it with a hose clamp. The strainer will help toprevent the pump from becoming clogged or damaged by debris.
Use a hose clamp to securely fasten the hose connector to the suctionhose in order to prevent air leakage and loss of suction. Verify that thehose connector sealing washer is in good condition.
The suction hose should be no longer than necessary. Pumpperformance is best when the pump is near the water level, and thehoses are short.
Do not use a hose smaller than the pump’s suction port size.
Use a commercially available hose and hose connector with the hoseclamp provided with the pump. The suction hose must be reinforcedwith a noncollapsible wall or braided wire construction.
Minimum hose size: WB20X = 2 in (50 mm)WB30X = 3 in (80 mm)

It is best to use a short, large-dia-meter hose, because that willreduce fluid friction and improvepump output. A long or small-diameter hose will increase fluidfriction and reduce pump output.
Before starting the engine, remove the filler cap from the pumpchamber, and completely fill the pump chamber with water. Reinstallthe filler cap, and tighten it securely.
Operating the pump dry will destroy the pump seal. If the pump hasbeen operated dry, stop the engine immediately, and allow the pumpto cool before priming.

SERVICING YOUR PUMP
FUEL RECOMMENDATIONS
Use unleaded gasoline with a pump octane rating of 86 or higher.
Never refuel the engine inside a building where gasoline fumes mayreach flames or sparks. Keep gasoline away from appliance pilot lights,barbecues, electric appliances, power tools, etc.
Spilled fuel is not only a fire hazard, it causes environmental damage.Wipe up spills immediately.
Fuel can damage paint and plastic. Be careful not to spill fuel whenfilling your fuel tank. Damage caused by spilled fuel is not coveredunder warranty.
These engines are certified to operate on unleaded gasoline. Unleadedgasoline produces fewer engine and spark plug deposits and extendsexhaust system life.
Never use stale or contaminated gasoline or an oil/gasoline mixture.Avoid getting dirt or water in the fuel tank.
Occasionally you may hear a light ‘‘spark knock’’ or ‘‘pinging’’(metallic rapping noise) while operating under heavy loads. This is nocause for concern.
If spark knock or pinging occurs at a steady engine speed, undernormal load, change brands of gasoline. If spark knock or pingingpersists, see an authorized Honda servicing dealer.
Running the engine with persistent spark knock or pinging can causeengine damage.
Running the engine with persistent spark knock or pinging isconsidered misuse, and the Distributor’s Limited Warranty does notcover parts damaged by misuse.

A dirty air filter will restrict air flow to the carburetor, reducing engineperformance. If you operate the pump in very dusty areas, clean theair filter more frequently than specified in the MAINTENANCESCHEDULE (see page ).
Clean the air filter in warm soapy water, rinse, and allow to drythoroughly. Or clean in nonflammable solvent and allow to dry.
Dip the air filter in clean engine oil, then squeeze out all excess oil.The engine will smoke when started if too much oil is left in thefoam.
Wipe dirt from the air cleaner base and cover, using a moist rag. Becareful to prevent dirt from entering the air duct that leads to thecarburetor.

STORAGE PREPARATION
Cleaning
Proper storage preparation is essential for keeping your pump trouble-free and looking good. The following steps will help to keep rust andcorrosion from impairing your pump’s function and appearance, andwill make the engine easier to start when you use the pump again.
Wash the engine and pump.
Wash the engine by hand, and be careful to prevent water fromentering the air cleaner or muffler opening. Keep water away fromcontrols and all other places that are difficult to dry, as waterpromotes rust.
Using a garden hose or pressure washing equipment can forcewater into the air cleaner or muffler opening. Water in the aircleaner will soak the air filter, and water that passes through theair filter or muffler can enter the cylinder, causing damage.
Water contacting a hot engine can cause damage. If the enginehas been running, allow it to cool for at least half an hour beforewashing.
Wipe dry all accessible surfaces.
Fill the pump chamber with clean, fresh water, start the engineoutdoors, and let it run until it reaches normal operatingtemperature to evaporate any external water.
Dry operation will damage the pump seal. Be sure the pumpchamber is filled with water before starting the engine.

PUMP DRAIN PLUG
Stop the engine, and allow it tocool.
Remove the pump drain plug,and flush the pump with clean,fresh water. Allow the water todrain from the pump chamber,then reinstall the drain plug.
After the pump is clean and dry,touch up any damaged paint,and coat areas that may rustwith a light film of oil. Lubricatecontrols with a silicone spraylubricant.
Gasoline will oxidize and deteriorate in storage. Old gasoline willcause hard starting, and it leaves gum deposits that clog the fuelsystem. If the gasoline in your engine deteriorates during storage, youmay need to have the carburetor and other fuel system componentsserviced or replaced.
The length of time that gasoline can be left in your fuel tank andcarburetor without causing functional problems will vary with suchfactors as gasoline blend, your storage temperatures, and whether thefuel tank is partially or completely filled. The air in a partially filled fueltank promotes fuel deterioration. Very warm storage/temperaturesaccelerate fuel deterioration. Fuel deterioration problems may occurwithin a few months, or even less if the gasoline was not fresh whenyou filled the fuel tank.
The Distributor’s Limited Warranty does not cover fuel systemdamage or engine performance problems resulting from neglectedstorage preparation.
You can extend fuel storage life by adding a fuel stabilizer that isformulated for that purpose, or you can avoid fuel deteriorationproblems by draining the fuel tank and carburetor.

Engine Oil
STORAGE PRECAUTIONS
Align notch on pulley withhole at top of cover.
Change the engine oil (see page ).
Remove the spark plug (see page ).
Pour a tablespoon (5 10 cc) of clean engine oil into the cylinder.
Pull the starter grip several times to distribute the oil in the cylinder.
Reinstall the spark plug.
Unless all fuel has been drained from the fuel tank, leave the fuel valvelever in the OFF position to reduce the possibility of fuel leakage.
If possible, avoid storage areas with high humidity, because thatpromotes rust and corrosion.
If your pump will be stored with gasoline in the fuel tank andcarburetor, it is important to reduce the hazard of gasoline vaporignition. Select a well-ventilated storage area away from any appliancethat operates with a flame, such as a furnace, water heater, or clothesdryer. Also avoid any area with a spark-producing electric motor, orwhere power tools are operated.
Pull the recoil starter grip slowly until resistance is felt and the notchon the starter pulley aligns with the hole at the top of the recoilstarter cover. This will close the valves so moisture cannot enter theengine cylinder. Return the recoil starter grip gently.

STORAGE
REMOVAL FROM STORAGE
Place the pump on a level surface. Tilting can cause fuel or oil leakage.
With the engine and exhaust system cool, cover the pump to keep outdust. A hot engine and exhaust system can ignite or melt somematerials. Do not use sheet plastic as a dust cover. A nonporous coverwill trap moisture around the pump, promoting rust and corrosion.
Check your pump as described in the BEFORE OPERATION chapter ofthis manual.
If the fuel was drained during storage preparation, fill the tank withfresh gasoline. If you keep a container of gasoline for refueling, besure that it contains only fresh gasoline. Gasoline oxidizes anddeteriorates over time, causing hard starting.
If the cylinder was coated with oil during storage preparation, theengine may smoke briefly at startup. This is normal.

TRANSPORTING
If the pump has been running, allow the engine to cool for at least 15minutes before loading the pump on the transport vehicle. A hotengine and exhaust system can burn you and can ignite somematerials.
Keep the pump level when transporting to reduce the possibility offuel leakage. Move the fuel valve lever to the OFF position.

Carburetor Modification for High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be toorich. Performance will decrease, and fuel consumption will increase. Avery rich mixture will also foul the spark plug and cause hard starting.Operation at an altitude that differs from that at which this engine wascertified, for extended periods of time, may increase emissions.
High altitude performance can be improved by specific modificationsto the carburetor. If you always operate your pump at altitudes above5,000 feet (1,500 meters), have your servicing dealer perform this car-buretor modification. This engine, when operated at high altitude withthe carburetor modifications for high altitude use, will meet eachemission standard throughout its useful life.
Even with carburetor modification, engine horsepower will decreaseabout 3.5% for each 1,000-foot (300-meter) increase in altitude. Theeffect of altitude on horsepower will be greater than this if nocarburetor modification is made.
When the carburetor has been modified for high altitude operation,the air-fuel mixture will be too lean for low altitude use. Operation ataltitudes below 5,000 feet (1,500 meters) with a modified carburetormay cause the engine to overheat and result in serious engine damage.For use at low altitudes, have your servicing dealer return thecarburetor to original factory specifications.

Oxygenated Fuels
METHANOL
MTBE
ETHANOL
Some conventional gasolines are being blended with alcohol or anether compound. These gasolines are collectively referred to asoxygenated fuels. To meet clean air standards, some areas of theUnited States and Canada use oxygenated fuels to help reduceemissions.
If you use an oxygenated fuel, be sure it is unleaded and meets theminimum octane rating requirement.
Before using an oxygenated fuel, try to confirm the fuel’s contents.Some states/provinces require this information to be posted on thepump.
The following are the EPA approved percentages of oxygenates:
(methyl tertiary butyl ether) 15% by volumeYou may use gasoline containing up to 15% MTBE byvolume.
(ethyl or grain alcohol) 10% by volumeYou may use gasoline containing up to 10% ethanolby volume. Gasoline containing ethanol may bemarketed under the name Gasohol.
(methyl or wood alcohol) 5% by volumeYou may use gasoline containing up to 5% methanolby volume, as long as it also contains cosolvents andcorrosion inhibitors to protect the fuel system.Gasoline containing more than 5% methanol byvolume may cause starting and/or performanceproblems. It may also damage metal, rubber, andplastic parts of your fuel system.
If you notice any undesirable operating symptoms, try another servicestation, or switch to another brand of gasoline.
Fuel system damage or performance problems resulting from the useof an oxygenated fuel containing more than the percentages ofoxygenates mentioned above are not covered under warranty.

Source of Emissions
The combustion process produces carbon monoxide, oxides ofnitrogen, and hydrocarbons. Control of hydrocarbons and oxides ofnitrogen is very important because, under certain conditions, theyreact to form photochemical smog when subjected to sunlight. Carbonmonoxide does not react in the same way, but it is toxic.
Honda utilizes lean carburetor settings and other systems to reducethe emissions of carbon monoxide, oxides of nitrogen andhydrocarbons.
EPA and California regulations require all manufacturers to furnishwritten instructions describing the operation and maintenance of emis-sion control systems.
The following instructions and procedures must be followed in orderto keep the emissions from your Honda engine within the emissionstandards.
Tampering with or altering the emission control system may increaseemissions beyond the legal limit. Among those acts that constitutetampering are:
Removal or alteration of any part of the intake, fuel or exhaustsystems.
Altering or defeating the governor linkage or speed-adjustingmechanism to cause the engine to operate outside its designparameters.

The emission control systems on your Honda engine were designed,built, and certified to conform with EPA and California emissionregulations. We recommend the use of genuine Honda partswhenever you have maintenance done. These original-designreplacement parts are manufactured to the same standards as theoriginal parts, so you can be confident of their performance. The useof replacement parts that are not of the original design and qualitymay impair the effectiveness of your emission control system.
A manufacturer of an aftermarket part assumes the responsibility thatthe part will not adversely affect emission performance. Themanufacturer or rebuilder of the part must certify that use of the partwill not result in a failure of the engine to comply with emissionregulations.
Follow the maintenance schedule (see page ). Remember that thisschedule is based on the assumption that your machine will be usedfor its designed purpose. Sustained high-load or high-temperatureoperation, or use in unusually wet or dusty conditions, will requiremore frequent service.
