Connecting Hoses Note: Hose coupling components and hoses not included. Safety Note: The Suction Hose (not included) MUST be reinforced with braided material or have non‑collapsible construction. Do not use a hose with an inside diameter smaller than 3" (pump’s intake and discharge port diameters). 3. Slide one of the Hose Clamps over the end of the suction hose (a). Slide the Hose onto the Hose Coupler (b). Use a screwdriver (not included) to tighten the Hose Clamp until secure.
5. For the discharge hose, slide a Hose Coupling Ring over the remaining Hose Coupler (a) and place a Gasket onto the end of the Hose Coupler (b) (all not included). 7. Slide a Hose Clamp over the end of the Discharge Hose (a). Slide the Discharge Hose onto the Hose Coupler (b). Use a screwdriver to tighten the Hose Clamp until secure. Safety a b a b 6. Thread the Hose Coupling Ring clockwise onto the Discharge Port until tightened securely. Locating the Water Pump 1.
Operation Concerns 1. Cavitation: This is the sudden formation and collapse of low-pressure vapor (bubbles) across the vanes of the impeller. Safety Strainer 4. Secure the Intake Hose in place to keep it from moving once the Pump is turned on. The Intake Hose should be as short as possible for more efficient operation. Setup 5. Route the discharge hose to the desired discharge location. If necessary, connect additional discharge hoses to direct the discharge to the desired location.
Checking and Filling Engine Oil Full level Full level 1. Make sure the engine is stopped and is level. 2. Close the Fuel Valve. 3. Clean the top of the Dipstick and the area around it. Remove the Dipstick by threading it counterclockwise, and wipe it off with a clean lint free rag. 4. Reinsert the Dipstick without threading it in and remove it to check the oil level. The oil level should be up to the full level as shown above.
Manual Start Safety 1. To start a cold engine, move the Choke to the CHOKE position. To restart a warm engine, leave the Choke in the RUN position. 1 CHOKE RUN 2. Open the Fuel Valve. 2 Setup 3. Slide the Throttle or Speed Control Lever to 1/3 away from the SLOW position (the “turtle”). 3 Operation O OFF 4. Turn the Engine Switch on. Maintenance 5. Grip the Starter Handle of the Engine loosely and pull it slowly several times to allow the gasoline to flow into the Engine’s carburetor.
6. Allow the Engine to run for several seconds. Then, if the Choke lever is in the CHOKE position, move the Choke Lever very slowly to its RUN position. Note: Moving the Choke Lever too fast could stall the engine. 6 7. Adjust the Throttle as needed. Safety IMPORTANT: Allow the engine to run at no load for five minutes with no load after each start‑up so that the engine can stabilize. CHOKE RUN 8. Break-in Period: a. Breaking-in the engine will help to ensure proper equipment and engine operation.
Maintenance Safety WARNING TO PREVENT SERIOUS INJURY FROM ACCIDENTAL STARTING: Turn the Power Switch of the equipment to its “OFF” position, wait for the engine to cool, and disconnect the spark plug cap before performing any inspection, maintenance, or cleaning procedures. TO PREVENT SERIOUS INJURY FROM EQUIPMENT FAILURE: Do not use damaged equipment. If abnormal noise, vibration, or excess smoking occurs, have the problem corrected before further use. Follow all service instructions in this manual.
Checking and Filling Fuel Note: Do not use gasoline containing more than 10% ethanol (E10). Do not use E85 ethanol. Add fuel stabilizer to the gasoline or the Warranty is VOID. 7. Add the appropriate type of oil until the oil level is at the full level. SAE 10W‑30 oil is recommended for general use. The SAE Viscosity Grade chart shows other viscosities to use in different average temperatures.
Spark Plug Maintenance NOTICE: Using an incorrect spark plug may damage the engine. 4. When installing a new spark plug, adjust the plug’s gap to the specification on the Specifications chart. Do not pry against the electrode, the spark plug can be damaged. Spark Plug Cap Safety 1. Disconnect spark plug cap from end of plug. Clean out debris from around spark plug. 2. Using a spark plug wrench, remove the spark plug. 3.
Pump Troubleshooting 1. Incorrect lubrication or not enough lubrication. 2. Worn parts. 1. Low engine speed. Unit stalls 2. Severely clogged air filter. 3. Improper lubrication. 1. Pump is not primed. 2. Intake Strainer clogged. 3. Air leak at intake connector. 4. Hose leaks. Pump does not 5. Suction hose has pump water collapsing wall. 6. Hose has too small diameter. 7. Pump is too high above water surface. 1. Suction hose collapsed, damaged, too long or diameter is too small.
Troubleshooting Possible Causes Probable Solutions Engine will not start FUEL RELATED: 1. No fuel in tank or fuel valve closed. 2. Choke not in CHOKE position, cold engine. 3. Gasoline with more than 10% ethanol used. (E15, E20, E85, etc.) 9. Clogged Fuel Filter. FUEL RELATED: 1. Fill fuel tank and open fuel valve. 2. Move Choke to CHOKE position. 3. Clean out ethanol rich gasoline from fuel system. Replace components damaged by ethanol.
5. Incorrect compression. Engine stops suddenly 1. Low oil shutdown. 2. Fuel tank empty or full of impure or low quality gasoline. 3. Defective fuel tank cap creating vacuum, preventing proper fuel flow. 4. Faulty magneto. 5. Disconnected or improperly connected spark plug cap. 1. Check wire connections. 2. Re-gap or replace spark plug. 3. Replace spark plug cap. 4. Use only fresh 87+ octane stabilizertreated unleaded gasoline.
