Assembly Instructions ⚠WARNING CHECK and TEST the completed assembly as directed in this manual. Serious injury could result from water leaks if the water pump is improperly assembled. DO NOT MODIFY the water pump’s design. Required Assembly Tools Open-end wrenches:S10 and S8 Bolts:M6 Nuts:M6 Installation Steps 1. Ensure the handle mounting hole fits the base of the mounting holes. 2. Insert the bolt and screw in the nut by hand. 3.
Before Each Use Step One: Inspect & Repair If the water pump has been previously used, it must be prepared BEFORE EACH SUBSEQUENT USE. ⚠WARNING Read instructions below carefully for inspecting and preparing the water pump. Damaged or clogged equipment could result in leaks or uncontrolled spray. ⚠WARNING IMPORTANT SAFETY RULES Check oil. Before each use, check the oil level and add oil to the proper level if it's low. Turn off engine.
Step Two: Fueling ⚠WARNING Gasoline is highly flammable and explosive. Use extreme care when handling gasoline. A running engine is hot enough to ignite fuel. Never add fuel or remove gas cap if engine is running or still hot. Gasoline vapors can ignite if they collect inside an enclosure. Explosion can result. 1. Engine off / cool 2. Outdoor location The engine must be off and allowed to cool at least two minutes before adding fuel. Fill fuel tank outdoors – never indoors. 3.
Step Three: Attach a Suction Strainer ⚠WARNING This pump is designed to pump water only. Never use the water pump to pump flammable liquids. 1. Attach suction strainer A suction strainer should be attached to the suction hose. A suction strainer has holes or slots small enough to prevent large debris from working through and damaging the pump. 2. Keep the strainer clean Keep the strainer clean. If possible, suspend the strainer to keep it from working into sediment -ORa.
Operating Instructions Part 1: Operating the Water Pump ⚠WARNING Review safety information provided in this manual. Use the priming port on the top of the pump. Completely fill the pump chamber with water before starting the engine. Follow these safety rules and precautions when running the water pump’s engine: Hot muffler. If you are starting a warm engine, stay clear of the muffler. It may still be hot enough to burn you. Hot exhaust. Hot exhaust fumes from the engine can cause fire.
Part 2: Operating the Engine Safety Precautions ⚠WARNING Warning Symbol Description Rapid retraction of the starter cord (kickback) can jerk your hands toward the engine faster than you can let go. Broken bones, fractures, bruises, or sprains could result. When starting the engine, pull the cord slowly until resistance is felt, then pull rapidly. Components such as blades, impellers, pulleys, sprockets, etc., must be securely attached.
⚠WARNING Warning Symbol Description Gasoline and its vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death. When adding fuel: Turn the engine OFF and let the engine cool for at least 2 minutes before removing the gas cap. Fill the fuel tank outdoors or in a well-ventilated area. Do not overfill the fuel tank. Keep gasoline away from sparks, open flames, pilot lights, heat, and other ignition sources.
storing gasoline (free from smoking, flames, and sparks). 5. Refill the fuel tank, avoiding overfilling. If there is a fuel spill, be sure to clean thoroughly before operating. 6. Locate the engine on a level, working platform to avoid fuel spills. 7. Make sure the fuel filler cap is tightened securely. 8. The exhaust muffler will be very hot even after the engine stops running. Never touch it, or you may be burned. Transport or store the engine only after it has completely cooled.
Pre-Operation: Engine Oil Inspection ⚠CAUTION Engine oil is a key factor in the engine's performance. Do not apply engine oil with additives or 2-stroke gasoline oil. Check the engine while it’s stopped on level ground. The recommended engine oil is: SAE 10W-30. Viscosity varies by region and temperature, so the lubricant has to be selected in accordance with our recommendation. Check Engine 1. Ensure that the engine is stopped on level ground. 2. Remove the dipstick and clean it. 3.
If a "spark knock" or "pinking" occurs at a steady speed under the normal load, change the brand of gasoline; if such occurrences still happen, consult your dealer for help, otherwise the engine may be damaged. Check 1. Remove the fuel filler cap and check the fuel level. 2. If the fuel level is too low, refuel the tank. Do not fill the fuel over the fuel filler shoulder. Starting the Engine ⚠WARNING Gasoline is extremely flammable and is explosive under certain conditions.
4. Start the engine as follows (figure): With the hand-operated kick-starter, push the engine switch to ON. Pull slightly on the starting rope handle until feeling resistance, and then pull quickly. ⚠CAUTION Do not allow the starter grip to snap back against the engine. Return it gently to prevent damage to the starter. Oil Engine Alarm The engine oil alarm is designed to function when there is insufficient engine oil in the crankcase. Lack of engine oil may damage the engine.
⚠CAUTION Amended engine applicable to highlands may be damaged seriously in area below altitude of 1800 meters for overheating, because its mixture ratio is too small for operation in low altitude area. In the case, ask your dealer to recover the engine to its normal technical status. Stop the Engine In an emergency, turn the engine switch to OFF to stall the engine. In a normal situation, do the following (see figure): 1. Push the throttle lever to the bottom. 2. Push the engine switch to OFF. 3.
To keep the water pump at the optimal performance, checking and making adjustments periodically is necessary. Regular maintenance and service may extend its service life. The Maintenance Schedule below specifies how often you should have your water pump serviced and other areas that need attention.
Air Cleaner Maintenance A dirty air cleaner will decrease the airflow quantity through the carburetor. To avoid troubles with the carburetor, clean the air cleaner regularly. In extremely dusty areas, this should be done more often. WARNING: Never clean the air cleaner in gasoline or low-flash point solvent, for gasoline and lowflash point solvent may produce flames and even an explosion in certain conditions ⚠CAUTION Never operate the water pump without the air cleaner installed.
⚠WARNING When the engine has been running, the exhaust muffler is very hot and dangerously hot to the touch. 2. Check the spark plug visually. If there are signs of wear around it or the gasket is cracked, replace it with a new one. Before reinstalling a spark plug, clean it with a wire brush. 3. Measure the spark plug gap with a feeler gauge and adjust it by bending the side electrode. The spark plug clearance should be 0.70-0.80mm. 4.
⚠CAUTION Be sure to tighten the spark plug securely, otherwise it may become very hot and possibly damage the engine. Never use a spark plug with the improper heat range. Storage Prepare the water pump for end-of-season storage by running pure water through the system. This will flush out any contaminants and clean the water pump internals. After the water pump has been flushed with pure water, completely drain the water pump of all water to protect it from freezing.
3. Engine storage Refer to the engine manual for proper engine storage instructions. Always disable the engine for storage by unplugging the spark plug wire. 4. Water pump storage location Store the water pump in a location away from corrosive material, sources of heat, open flames, sparks or pilot lights. 5. Gasoline storage Store gasoline in a cool, dry place. Place in a tightly sealed container.
Failure Possible Cause Corrective Action seal Low capacity 1. Clogged suction hose Clear obstruction 2. Dirty suction strainer 3. Flow restriction due to hose kinks 4. Suction lift too high Clear suction strainer 5. Engine speed too low 6. Worn or broken mechanical seal 7. Reduced engine performance Increase engine speed 8. Clogged impeller Remove clog 9.
