Use commercially available hose, hose connector, and hose bands.
The suction hose must be of reinforced, non-collapsible construction. Suction hose length should not be longer than necessary, as pump performance is best when the pump is not far above the water level.
Self-priming time is also proportional to hose length.
The strainer that is provided with the pump should be attached to the end of the suction hose with a band, as shown.
Always install the strainer on the end of the suction hose before pumping. The strainer will exclude debris that can cause clogging or impeller damage.
Use a commercially available hose, hose connector, and hose band. A short, large-diameter hose is most efficient. Long or small-diameter hose increases fluid friction and reduces pump output.
NOTE:
Tighten the hose band securely to prevent the hose from disconnecting under high pressure.
Use high-detergent, premium quality 4-stroke engine oil, certified to meet or exceed U.S. automobile manufacturer's requirements for API service category SE or later (or equivalent).
Select the appropriate viscosity for the average temperature in your area.
AMBIENT TEMPERATURE
Remove the oil filler cap/dipstick and wipe it clean.
Insert the filler cap/dipstick into the oil filler neck, but do not screw it in. If the level is low, fill to the top of the oil filler neck with the recommended oil.
Running the engine with insufficient oil can cause serious engine damage.
The Oil Alert System is designed to prevent engine damage caused by an insufficient amount of oil in the crankcase. Before the oil level in the crankcase can fall below a safe limit, the Oil Alert System will automatically stop the engine (the engine switch will remain in the ON position).
If the engine stops and will not restart, check the engine oil level before troubleshooting in other areas.
Use automotive unleaded gasoline with a Research Octane Number of 91 or higher (a Pump Octane Number of 86 or higher).
Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting dirt or water in the fuel tank.
With the engine stopped and on a level surface, remove the fuel tank cap and check the fuel level.
Refill the tank if the fuel level is low.
Do not fill the fuel tank completely. Fill tank to approximately 25 mm (1 inch) below the top of the fuel tank to allow for fuel expansion. If may be necessary to lower the fuel level depending on operating conditions.
After refueling, make sure the tank cap is closed properly and securely.
NOTE:
Gasoline spoils very quickly depending on factors such as light exposure, temperature and time.
In worst cases, gasoline can be contaminated within 30 days. Using contaminated gasoline can seriously damage the engine (clogged carburetor, stuck valve).
Such damage due to spoiled fuel is disallowed from coverage by the warranty.
To avoid this please strictly follow these recommendations:
If you decide to use a gasoline containing alcohol (gasohol), be sure its octane rating is at least as high as that recommended by Honda. There are two types of ''gasohol'': one containing ethanol, and the other containing methanol.
Do not use gasohol that contains more than 10% ethanol.
Do not use gasoline containing more than 5% methanol (methyl or wood alcohol) and that does not also contain co-solvents and corrosion inhibitors for methanol.
NOTE:
Remove the wing nut, washer and air cleaner cover.
Check the element for dirt or obstruction. Clean the element if necessary.
Never run the engine without the air cleaner. Rapid engine wear will result from contaminants such as dust and dirt being drawn through the carburetor into the engine.
The pump chamber should be primed with full of water before operating.
Never attempt to operate the pump without priming water, or the pump will overheat. Extended dry operation will destroy the pump seal. If the unit has been operated dry, stop the engine immediately and allow the pump to cool before adding priming water.
At high altitude, the standard carburetor air-fuel mixture will be excessively rich. Performance will decrease, and fuel consumption will increase.
High altitude performance can be improved by specific modifications to the carburetor. If you always operate the pump at altitudes higher than 1,500 m (5,000 feet) above sea level, have your authorized Honda dealer perform these carburetor modifications.
Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for each 300 m (1,000 foot) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made.
Operation of the pump at an altitude lower than the carburetor is jetted for may result in reduced performance, overheating, and serious engine damage caused by an excessively lean air/fuel mixture.
Never use the pump for muddy water, rejected oil, wine, etc.
After starting the engine, move the throttle lever to the FAST position for self-priming, and check pump output.
Pump output is controlled by adjusting engine speed. Moving the throttle lever in the FAST direction will increase pump output, and moving the throttle lever in the SLOW direction will decrease pump output.
To stop the engine in an emergency, simply turn the engine switch to the OFF position. Under normal conditions, use the following procedure.
Before storing the pump for an extended period;
