Ⅰ. General Safeguards Safety Precautions Please read this operation manual to have a thorough understanding of the content there before use the product. Failure to do so may lead to personal injury or mechanical damage. Before starting the engine, perform inspections according to the procedures described on pre-operation inspections to avoid accidents and damage to your machine.
environment. No smoking is allowed and no open fire or sparks allowed to exist in areas where fueling is carried out or the fuel is stored. Do not allow the fuel to overflow the fuel tank. Be sure to recap the tank and tighten it after refueling. When fueling, take care not to spill the gasoline about as the gasoline vapor may easily get ignited to cause a fire hazard. Be sure to remove the spilled gasoline as by wiping before starting the engine.
Ⅱ.
Ⅲ. Operation before Starting Up 1. Connecting the water inlet Connect the water inlet with a commercially available hose, connector and fastener clip. The inlet hose must be a continuous non-foldable structure with a length not more than required and should be placed near to the source of water so as to achieve the pump should be fitted to the end of the hose with the hose connector as shown in the figure below.
NOTE: Be sure to the fastener clip is securely fastened to prevent the outlet hose from coming off under high water pressure. 3.Checking the oil level CAUTION: ·The oil is one of the major factors affecting engine performance and life. Do not use dirty oil or vegetable oil. ·Be sure to check the oil level with the engine shut down and placed on a level surface. Please use the SE15-40, 4-stroke engine oil as recommended.
the oil level comes up to the upper most position of the refilled if the existing oil level is found too low. CAUTON: ·Running the engine at a low oil level will cause damage to it. 4. Checking the fuel level Uncap the fuel tank and check the fuel level. Pouring gasoline if the fuel level is found too low. Please use the type of gasoline recommended by the Dealer (Using the low lead content or lead-free gasoline type is good for minimizing carbon deposits inside the combustion chamber).
·When fueling, take care not to spill the gasoline about as the gasoline vapor may easily get ignited to cause a fire hazard. Be sure to remove the spilled gasoline as by wiping before starting the engine. ·Avoid frequent or extensive exposure of the skin to gasoline or breathing in the gasoline vapor. Keep the gasoline out of the reach of children. ·Fuel tank capacity: 1.0 gallons (US. 3.6 liters) 5. Checking the air cleaner filter element Screw the wing nut and remove the washer and cleaner cover.
6. Checking and filling the pump with cooling water The pump must be filled with water before it is put to operation. CAUTION: ·Do not attempt running the pump without cooling water or the pump will get overheated. Extensive running without cooling water may also damage the air tightness of the pump. If the pump is found running dry, stop the engine and pouring in water when it cools down.
Ⅳ. Starting engine 1. Turn on the fuel tap (by setting it to the ON position). 2. Close the choke. NOTE: ·The choke is not required when starting the engine warm or the ambient temperature is rather high, (i.e. keep the choke open when starting the engine). 3. Set the engine switch to the ON position. 4. Turn the throttle control lever slowly to the left.
5. Gently pull up the starter lever until a resistance is felt and then quickly pull it up. CAUTION: ·Do not allow the starter lever to retract quickly into the engine. Let it go back gently to avoid damaging the starter. Ⅴ.Use in Highland Areas Operation in Highland Conditions In highland areas (with a high ASL elevation), the air-fuel mixture produced by a standard carburetor will be too thick and result in a reduced engine performance and soared fuel consumption.
·Using the water pump in areas where the ASL elevation is lower than suitable for the carburetor nozzle will lead to a decreased engine performance and overheating of the engine and even cause serious damage to the engine due to an extremely thin air-fuel mixture. Ⅵ. Operation of the Water Pump 1. Gradually open the choke after the engine warms up. 2. Set the throttle to the predetermined RPM. Ⅶ. Shutting Down the Engine 1. Set the throttle control lever to the right end.
2. Set the engine switch to the OFF position. 3. Turn off the fuel tap (by setting to the OFF position). NOTE: ·To shut down the engine in an emergency, simply set the engine switch to the OFF position. Ⅷ. Maintenance Periodic inspections and fine-tuning are simply indispensable to keep the water pump working with high performance and regular maintenance may also lengthen the pump life. Supplied in the table on the next page are intervals at which the schedules maintenance jobs are to be done.
CAUTION: ·In cases when the pump is used to suck up seawater, be sure to flush it with fresh water immediately after use to minimize corrosion and remove deposits. ·Always use the original parts and relevant tools supplied with the machine to carry out maintenance. Failure to do this may cause damage to the pump. NOTE: ⑴ Inspection and maintenance should take place more frequently if the pump is used in a dirty environment.
○* Water inlet Note: “*” items will be maintained with the help of dealers from general power machinery Co., Ltd. 1. Replacing the engine oil Oil drains easily and quickly while the engine is warm. 1. Remove the oil dipstick and drain bolt to let out the oil. 2. Screw the drain bolt back in place and tighten it. 3. Pour in clean oil until the desired level is reached. Oil sump capacity: 0.6 liters Clean the hands with soap if stained with the engine oil.
circumstances. CAUTION: Do not use the water pump without an air cleaner. The dirt or dust if sucked into the engine may quicken engine wear. 1) Unscrew the wing nut and remove the air cleaner cover and filter element. 2) Clean the filter element with a detergent solution inflammable or with a high ignition point and let it dry thoroughly after cleaning. 3) Immerse the filter element into clean oil and then squeeze out the excessive amount of oil.
obviously worn out or the insulation ring on it is broken or cracked. Clean the spark plug with a brush when put it back in place. 3) Check the plug gap with a feeler gauge. Vary the gap by moving the side electrode. Normal plug gap: 0.70~0.80mm 4) Check the plug O-ring for normal condition. Screw it in with the plug wrench to protect the plug thread.
tightening may cause the engine to be overheated or damaged. Never use spark plugs with an incorrect thermal value range. Ⅸ. Transportation and Storage CAUTION: ·To avoid causing a fire hazard, let the engine cool down before transportation or indoor storage of the pump. ·Before transporting the pump, set the fuel tap to the OFF position and place the pump body in a level position to prevent the fuel from spilling out. The spilled gasoline or the gasoline vapor may get ignited.
4) Replace the engine oil. 5) Screw off the spark plug, pour a spoonful of clean oil into the cylinder, turn the engine alternatively for several times to allow uniform distribution of oil, and then screw in the spark plug again. 6) Pull up the starter lever until a resistance is felt. Stop pull for a while and pull it up again until the triangle mark on the starter wheel gets into collimation with the screw hole in the starter (as shown the sketch below).
3) Has the fuel reached the carburetor? Make the check by unscrewing the oil drain screw from under the carburetor with the fuel tap turned on. WARNING: ·Should there be a spill of fuel, be sure to clean it before checking the spark plug and start the engine or otherwise the spilled fuel or fuel vapor may get ignited 4) Is the engine switch set to the ON position? 5) Is there enough oil in the crankcase? 6) Is the spark plug generating sparks? a.
The pump unable to such up water: 1) Is it filled with enough amount of water? 2) Is the filter clogged? 3) Is the hose fastener clip tightened? 4) Is the hose damaged? 5) Is the suction head too high? 6) If the pump still fails to work, send it to any of the authorized dealers.
