SAFETY WARNING SYMBOLS AND DEFINITIONS This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death. SETUP Indicates a hazardous situation which, if not avoided, will result in death or serious injury. Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
Safety Warnings SAFETY WARNING! Read all instructions. Failure to follow all instructions listed below may result in fire, serious injury and/or DEATH. The warnings and precautions discussed in this manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator. SAVE THESE INSTRUCTIONS Set up Precautions 1.
Operating Precautions (cont.) 14. Dress properly. Do not wear loose clothing or jewelry. Keep hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts. 15. Parts, especially exhaust system components, get very hot during use. Stay clear of hot parts. 16. Do not cover the engine or equipment during operation. 17. Keep the equipment, engine, and surrounding area clean at all times. 18. Use the equipment, accessories, etc.
Set Up Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product. SAFETY TO PREVENT SERIOUS INJURY: Operate only with proper spark arrestor installed. Operation of this equipment may create sparks that can start fires around dry vegetation. A spark arrestor may be required. The operator should contact local fire agencies for laws or regulations relating to fire prevention requirements.
Connecting Hoses 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 2″ (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. CAUTION: Use only a non-collapsible intake hose.
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). a 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. b SAFETY b a 6. Thread the Hose Coupling Ring clockwise onto the Discharge Port until tightened securely.
Locating the Water Pump 1. For best Pump performance, place the Pump near the water level and use hoses that are no longer than necessary. This will allow the Pump to produce the greatest output with the least self-priming time. See diagram below. As the head (pumping height) increases, pump output decreases. The length, type, and size of the suction and discharge hoses can also significantly affect Pump output. Discharge head capability is always greater than suction head capability.
Operation Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product. SAFETY Prime the Pump Before starting the engine, fill the Pump with water. To do this: 1. Unthread the Priming Water Filler Cap by turning it counterclockwise. 2. Fill the unit with clean water up to the top of the opening. Replace the Priming Water Filler Cap and tighten securely.
Starting the Engine 1 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. CHOKE RUN 2 3. Slide the Throttle to 1/3 away from the SLOW position (the “turtle”). 3 SETUP 2. Open the Fuel Valve. OFF 4. Turn the Engine Switch on. ON 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.
8. Break-in Period: a. Breaking-in the engine will help to ensure proper equipment and engine operation. b. The operational break-in period will last about 3 hours of use. During this period: • Do not apply a heavy load to the equipment. SAFETY • Do not operate the engine at its maximum speed. c. The maintenance break-in period will last about 20 hours of use. After this period: • Change the engine oil. Note: Failure to change the oil regularly may damage the engine and void the warranty.
Maintenance and Service 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. 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.
SAFETY Checking and Filling Fuel Engine Oil Change WARNING! TO PREVENT SERIOUS INJURY FROM FIRE: Fill the fuel tank in a well-ventilated area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it to cool before adding fuel. Do not smoke. CAUTION! Oil is very hot during operation and can cause burns. Wait for engine to cool before changing oil. 1. Clean the Fuel Cap and the area around it. 4.
Spark Plug Maintenance SAFETY Spark Plug Cap Filter Cover Filter Cover Tab Filter 1. Disconnect spark plug cap from end of plug. Clean out debris from around spark plug. Base Hinge 2. Using a spark plug wrench, remove the spark plug. 2. Cleaning: • Foam filter element: Wash the element in warm water and mild detergent several times. Rinse. Squeeze out excess water and allow it to dry completely. Soak the filter in lightweight oil briefly, then squeeze out the excess oil. 3.
Storage SAFETY When the equipment is to remain idle for longer than 20 days, prepare the engine for storage as follows: c. Remove the small sediment cup next to the bowl and allow the fuel to drain from there as well. 1. CLEANING: Wait for engine to cool, then clean engine with dry cloth. NOTICE: Do not clean using water. The water will gradually enter the engine and cause rust damage. Apply a thin coat of rust preventive oil to all metal parts. d. Open the fuel valve.
Pump Troubleshooting Unit stalls Pump does not pump water Likely Solutions 1. Lubricate using recommended oil or grease according to directions. 2. Have qualified technician inspect internal mechanism and replace parts as needed. 1. Low engine speed. 2. Severely clogged air filter. 3. Improper lubrication. 1. Qualified technician should increase no load speed to 3,800±100 RPM by adjusting pressure switch. 2. Replace air filter. 3. Check for proper oil level. 1. 2. 3. 4. 5. 6. 7. 1. 2. 3. 4. 5. 6.
Engine Troubleshooting Problem Engine will not start Possible Causes SAFETY 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.) 4. 5. 6. SETUP 7. 8. 9. Probable Solutions 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.
Engine Troubleshooting (cont.) 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. 3. Replace spark plug cap. 4. Use only fresh 87+ octane unleaded gasoline. Do not use gasoline with more than 10% ethanol (E15, E20, E85, etc.). 5. Diagnose and repair compression.
