3. PRE-OPERATION CHECK
3.1 Check the Suction and Discharge Hoses
3.1.1 Check the general condition of the hoses. Be sure the hoses are in serviceable
condition before connecting them to the pump. Remember that the suction hose must
be reinforced construction to prevent hose collapse.
3.1.2 Check that the sealing washer in the suction hose connector is in good condition.
3.1.3 Check that the hose connectors and clamps are securely installed.
3.1.4 Check that the strainer is in good condition and is installed on the suction hose.
3.2 Check the Engine
3.2.1 Check the oil level. To avoid the inconvenience of an unexpected shut-down by the
Oil Alert system, always check the engine oil level before startup.
3.2.2 Check the air filter. A dirty air filter will restrict air flow to the carburetor, reducing
engine and pump performance.
3.2.3 Check the fuel level. Starting with a full tank will help to eliminate or reduce operating
interruptions for refueling.

4.1 Operating Controls
4.1.1 The centrifugal pump is operated using the engine operating controls. The engine
controls are located at the engine end of the pump frame.
4.1.2 The controls consist of a throttle lever (for speed control), choke lever (for cold weather
by hand). (Refer to Figure-3.)
4.2. Check the Engine Oil Level
FIGURE-3
• ENGINE OIL IS A MAJOR FACTOR AFFECTING PERFORMANCE AND SERVICE LIFE.
NON-DETERGENT OILS AND 2-STROKE OILS ARE NOT RECOMMENDED BECAUSE
THEY HAVE INADEQUATE LUBRICATING CHARACTERISTICS
• CHECK THE OIL LEVEL WITH THE ENGINE ON A LEVEL SURFACE AND THE ENGINE
STOPPED.
WARNING
10
4.3 Motor Oil
Use Honda 4-stroke oil, or use an equivalent high detergent, premium quality motor oil
certified to meet or exceed U.S. automobile manufacturer’s requirements for Service
Classification SG, SF. Motor oils classified SG, SF will show this designation on the container.
SAE 10W/30 is recommended for general, all-temperature use. Other viscosity grades (see
Figure-4) may be used when the average temperature in your area is within the indicated
range.
4.4 Checking Oil

4.4.1 Make sure the engine is in a level position.
4.4.2 Remove the oil filler cap/dipstick and wipe it clean.
4.4.3 Insert the filler cap/dipstick into the oil filler neck, but do not screw it in.
4.4.4 Remove the filler cap/dipstick and check the oil level.
4.4.5 If the level is low, fill to the top of the oil filler neck with the recommended oil.
4.4.6 Reinstall the oil filler cap/dipstick.
4.5 Priming the Pump
4.5.1 Before starting the water pump’s engine, remove priming plug from top of pump and
completely fill the chamber with water.
4.5.2 Reinstall the priming plug and tighten it securely.
FIGURE-4 FIGURE-5
OPERATING THE WATER PUMP DRY WILL DAMAGE THE PUMP’S SEAL. IF THE WATER
PUMP HAS BEEN OPERATED DRY, STOP THE ENGINE IMMEDIATELY AND ALLOW THE
MACHINE TO COOL BEFORE PRIMING THE PUMP USING THE STEPS ABOVE.
