Safety Instructions 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. For your safety read this manual carefully. Become familiar with the proper operation, care, and maintenance of your LIFAN Power USA water pump. The safety and alert symbol ( ) is used with a signal word (CAUTION, DANGER, WARNING), a pictorial and/or safety message to alert you to hazards.
Safety Instructions (continued) WARNING! Rapid recoil of starter cord (kickback) may pull hand and arm forward toward engine at a rapid rate. Broken bones, bruises, sprains, and fractures may result. When starting engine, pull cord slowly until tension is felt, then pull rapidly to avoid kickback. WARNING! Fuel and its vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death.
Safety Instructions (continued) WARNING! While engine is running temperature may exceed 150°F (65°C). Server burns may occur. Exhaust heat/gasses can ignite combustibles, structures or damage fuel tank causing a fire. Do NOT touch hot surfaces and do avoid exhaust gasses. Allow water pump to cool before touching. Keep at least 6 ft. (183cm) clearance on all sides of water pump including overhead clear. Reflective exhaust heat may damage fuel tank causing fire.
Controls and Features Legend 1. Throttle Valve Lever – Controls Engine Speed 2. Choke Lever – LF4WP Model: Before starting cold water pump, pull the choke pin outward from water pump to activate the choke lever. After allowing water pump to run for a few seconds, push pin inward toward water pump. LF2WP & LF3WP Models: Before starting cold water pump, rotate the choke lever to the left until resistance is felt. After starting the water pump, rotate the choke lever to the right to disengage. 3.
Pre-Operating Instructions: Connecting Water Inlet Hose Use commercially available hose, hose joint, and clamp. The water inlet hose must be of continuous structure and be non-folded. The length of the hose should be no more than required. The effect of suction is greatest at shorter distances from the water surface. Suction time varies with the length of the water inlet hose. The filter matching with the water pump should be mounted to the end of the water inlet hose with a hose clamp.
Pre-Operating Instructions: Connecting Water Outlet Hose Use commercially available hose, hose joint, and clamp. A short hose with a big diameter will provide the best performance. A long hose with a small diameter will increase flowing resistance and decrease the power output of the water pump. NOTE: Tighten the hose clamp to keep from disengaging during operation under high pressure. 11 LIFAN Power USA 2205 Industrial Park Road Van Buren, AR 72956 866-471-7464 www.lifanpowerusa.
Pre-Operating Instructions: Engine Oil Level Check CAUTION: Running engine with insufficient engine oil can cause severe damage to the engine. The engine performance and service life is directly dependent of the quality of the engine oil. Do NOT use filthy engine oil or vegetable oil. Check engine oil level only with engine stalled and with unit on level ground. o Use 4-Stroke Gasoline Engine Oil equivalent in quality with SF, SG from API. Oil velocity varies with average environmental temperature.
Pre-Operating Instructions: Engine Fuel Level Check CAUTION: Gasoline is extremely flammable. Keep away from ignition sources. Fuel unit only in well-ventilated areas with the engine stalled. Do NOT smoke near unit. Do NOT spill fuel out of the fuel tank. Spilled gasoline and gasoline vapor may ignite. If gasoline is spilled, wipe completely dry before starting the engine. Avoid repeated or sustained breathing of gasoline. Avoid skin contact with gasoline.
Pre-Operating Instructions: Air Cleaner Element Check CAUTION: Do NOT run the engine without air cleaner element installed. Operation of engine without air cleaner element installed will result in the inhalation of dirt, dust, and other debris into the engine and through the carburetor. This will result in premature wear of the engine. To Check Air Cleaner Element: 1.
Pre-Operating Instructions: Pump Water Capacity Check CAUTION: Do NOT run engine without water inside the pump. Operation of engine without water inside the pump will cause the pump to overheat. Prolonged operation of engine without water inside the pump will damage the pump gasket and impeller. If water within the pump is not full, shut off the engine at once and fill the pump after allowing the unit to cool. To Check Pump Water: 1. 2. 3. 4. Remove Water Filler Cap.
Operation of Water Pump Water Pump Use Location: WARNING! Running water pump gives off carbon monoxide gas. It is odorless, colorless, and highly toxic. Breathing carbon monoxide gas can leads to fainting, nausea or may result in death. Only operate water pump outdoors. Prevent exhaust gas from entering, through windows doors or ventilation intakes, any confined areas. DO NOT operate water pump inside any enclosed or roofed areas.
1. Operation of Water Pump (continued) Starting the Engine: Refer to the Controls and Features section for additional diagrams and definitions. 1. Prime the pump. 2. Move the fuel cock to the “ON” position. 3. To start a cold engine, refer to instruction in the Controls and Features section – 2. Choke lever. To restart a warm engine, leave the choke level in the “OPEN” position. 4. Move the throttle valve lever away from the “LOWER” position, about 1/3 of the way toward the “UPPER” position. 5.
Operation of Water Pump (continued) Stopping the engine: Refer to the Controls and Features section for additional diagrams and definitions. IN EMERGENCY: 1. Turn the engine switch to the “OFF” position. NORMAL PROCEDURE: 1. 2. 3. 4. 5. Move the throttle valve lever to the “LOWER” position. Turn the engine switch to the “OFF” position. Turn the fuel cock to the “OFF” position. Remove the water drain plug and drain the pump chamber.
Transporting and Storing the Unit CAUTION: To avoid fire, allow water pump to cool down for at least twenty (20) minutes before transporting or storing the unit. Always transport and store the unit with the fuel cock in the “OFF” position. Always keep unit in horizontal position to the ground to prevent fuel from spilling. Spilled gasoline and gasoline vapor may ignite. Gasoline is extremely flammable and explosive.
Transporting and Storing the Unit (continued) 9.
