Slide the Discharge Hose onto the Hose Coupler (b). Use a screwdriver to tighten the Hose Clamp until secure. Safety b Discharge Port Setup a 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.
Safety 5. Route the discharge hose to the desired discharge location. If necessary, connect additional discharge hoses to direct the discharge to the desired location. Make sure to secure the discharge hose in place to keep it from moving once the Water Pump is turned on. The discharge hose should be kept as short as possible for more efficient operation. Operation Concerns 1. CAVITATION: This is the sudden formation and collapse of low-pressure vapor (bubbles) across the vanes of the impeller.
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. 1. Clean the Fuel Cap and the area around it. 2. Unscrew and remove the Fuel Cap. 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.
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. Then pull the Starter Handle gently until resistance is felt. Allow Cable to retract fully and then pull it quickly. Repeat until the engine starts. Safety Note: Do not let the Starter Handle snap back against the engine. Hold it as it recoils so it doesn’t hit the engine. 5 6. Allow the Engine to run for several seconds.
Maintenance and Service 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.
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. 3.
Spark Plug Maintenance 1. To remove the air filter cover, push in and lift up on the Filter Cover Tab, pivoting the cover at the Base Hinge. Remove the filter and check for dirt.

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. Pull Starter Handle to distribute oil in cylinder.
Pump Troubleshooting Unit stalls 1. Incorrect lubrication or not enough lubrication. 2. Worn parts. 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. 1. Qualified technician should increase no load speed to 3,800±100 RPM by adjusting pressure switch. 2. Clean air filter. 3. Check for proper oil level. 2. Severely clogged air filter. 3. Improper lubrication.
Engine Troubleshooting Problem Engine will not start Possible Causes Probable Solutions Safety FUEL RELATED: 1. No fuel in tank or fuel valve closed. 2. Choke not in START position, cold engine. 3.
