Extended dry opera- tion will destroy the mechanical seal. If the unit has been operated dry, stop the engine immediately and al- low the pump to cool before adding priming water. -4- 4. STARTING THE ENGINE 1. Open the fuel cock. 2. Set the speed control lever to “START.” 3. Close the choke lever. If the engine is warm or the ambient temperature is high, close the choke lever half-way, or keep it open fully. If the engine is cold, or the ambient temperature is low, close the choke lever. -5- 4. Pull the starter handle slowly until re- sistance is felt. This is the "compression" point. Return the handle to its original position and pull swiftly. H Do not pull out the rope all the way. H After starting the engine, allow the starter handle return to its original position while still holding the handle. -6- 5.OPERATION 1. After starting the engine, gradually open choke by turning the choke lever and finally keep it open fully. Do not fully open the choke lever im- mediately when the engine is cold or the ambient temperature is low, be- cause the engine may stop. 2. After the engine starts, set the speed control lever at the low speed position (L) and warm it up without a load for a few minutes. Gradually move the speed control lever to- ward the high speed position (H) and set it at the required engine speed. NOTE : Whenever high speed operation is not re- quired, slow the engine down (idle), by mov- ing the speed control lever to save fuel and extend engine life. Avoid operating the engine at high speed for a long time without load. -7- I 6. STOPPING THE ENGINE 1. Set the speed control lever to the low speed position and allow the engine to run at low speed for 2 or 3 minutes before stopping. 2. Keep depressing the STOP BUTTON until the engine stops. Do not stop the engine suddenly when it is running at high speed. 3. Close the fuel cock. 4. Pull the starter handle slowly and return the handle to its original position when resistance is felt. NOTE : The above operation is necessary to prevent outside moist air from intruding into the combustion chamber. STOPPING ENGINE WITH THE FUEL COCK Close the fuel cock and wait for a while until the engine stops. Avoid letting fuel remain in the carburetor long period, or the passages of the carbu- retor may become clogged with impurities, and malfunctions may result. -8- DAILY INSPECTION Before running the pump, check the following service items: a Enough fuel. a Excessive vibration, noise. a Clean air cleaner element. Safe surroundings. Leakage of gasoline. a Loose or broken bolts and nuts. m Check the priming water. PERIODIC INSPECTION Periodic maintenance is vital to the safe and efficient operation of your pump. Check the table below for periodic maintenance intervals. The following chart is based on the normal pump operation schedule. lhours 50hours 200 hours 500 1000 (daily) (weekly) (monthly) hours hours Clean engine and check bolts and nuts. 0 (daily) Clean spark plug. 0 Clean air cleaner. 0 ~ Remove the pump casing and clean. 0 Clean fuel strainer. 0 Clean and adjust spark plug gap. 0 Clean and adjust carburetor. 0 Clean fuel tank. 0 Overhaul engine. 0 0 [CAUTION] a Replace rubber pipes for fuel passage every two years. If fuel leakage is found, replace the pipe immediately. -9- 0. "HOW-TO"MAINTENANCE INSPECTING THE SPARK PLUG Clean off carbon deposits on the plug electrode using a plug cleaner or wire brush. w Check electrode gap. Adjust it to between 0.02 and 0.03 inches. (0.6 and 0.7mm) I 0.6to 0.7" -+- (0.02to 0.03 in.) CLEANING AIR CLEANER Remove the element and clean it with kero- sene. Then soak it in a mixture of 3 parts ELEMENT kerosene and 1 part engine oil, squeeze out the excess and install the elenent. CLEANING MUFFLER If solid carbon deposits to the exhaust port of cylinder or both inlet and outlet of the muffler to reduce these holes, it may cause a low output. In such a case, remove carbon deposit after detaching the muffler. However, particularly by careful not to damage the piston and cylinder or not to allow ingress of carbon into the crankcase. FUEL PIPE REPLACEMENT Replace the fuel pipe every 2 years. Iffuel leakage is found, replace it immediately. -10 - CHECKING BOLTS, NUTS AND SCREWS Retighten loose bolts and nuts. Check for fuel and oil leaks. Replace damaged parts with new ones. Keep safety on your mind. CLEANING FUEL STRAINER w Loosen the banjo bolt from the carburetor and remove the strainer (plastic mesh). w Clean the strainer with kerosene and reassemble it. -11 - Pump does not Engine does not start. run.
