1、 BE HUMBLE IN LEARNING AND ACTIVELY PARTICIPATE IN THE PRE USE TRAINING FOR MICRO TILLAGE MACHINES ORGANIZED BY THE AGRICULTURAL MACHINERY DEPARTMENTONE IS TRAINING IN OPERATION AND MAINTENANCE TECHNIQUES, AND THE OTHER IS TRAINING IN AGRICULTURAL SERVICE MANAGEMENT SKILLS. THERE ARE MANY PLACES TO LEARN, SUCH AS THE USE OF DIESEL ENGINES, THE SELECTION OF ROTARY TILLAGE TOOLS, FIELD TRANSFER, CULTIVATION TECHNIQUES, MAINTENANCE, ETC. THE BETTER THE TRAINING, THE BETTER THE OPERATOR'S SKILLS, AND THE BETTER THE MAINTENANCE, THE BETTER THE PERFORMANCE OF THE MACHINE, WHETHER IT SAVES OIL OR HAS GOOD OPERATION QUALITY, AND THE BETTER THE ECONOMIC BENEFITS. FOR EXAMPLE, IN THE SIMPLEST CASE OF STARTING A MACHINE, SOME OPERATORS DID NOT ATTEND TRAINING, DID NOT GRASP THE TECHNICAL ESSENTIALS, AND STARTED THE MICRO TILLER INCORRECTLY, WHICH WAS VERY DIFFICULT. THEY OFTEN DAMAGED THE STARTING DISC, SPRING, AND ROPE. FOR EXAMPLE, SOME MACHINE OPERATORS HAVE LOW EYE SKILLS AND DO NOT FOLLOW THE GENERAL OPERATION SEQUENCE OF EASY FIRST, DIFFICULT SECOND, AND CULTIVATING DRY LAND FIRST, THEN PADDY FIELDS. THEY IMMEDIATELY ENTER THE WATER FIELD TO CULTIVATE WITH A NEW MACHINE OPERATOR, RESULTING IN MANY HUMAN MALFUNCTIONS SUCH AS WATER PLANTING, GEAR JAMMING, AND BEING STUCK IN THE FIELD AND UNABLE TO COME OUT. BUT THERE IS ALSO A GROUP OF SKILLED OPERATORS WHOSE MICRO CULTIVATORS WERE BOUGHT IN 2005 AND 2006. DUE TO GOOD MAINTENANCE AND CORRECT OPERATION METHODS, THE MACHINES HAVE NOT HAD ANY MAJOR PROBLEMS SO FAR. THE ANNUAL WORKLOAD IS OVER 150 ACRES, AND THE CULTIVATION QUALITY IS ALSO GOOD. FARMERS HAVE HIGH EVALUATIONS.2、 MACHINES SHOULD BE RUN IN BEFORE USENEW AND OVERHAULED MICRO CULTIVATORS MUST UNDERGO PROPER RUNNING IN IN IN ORDER TO ACHIEVE THEIR EXPECTED COMPREHENSIVE EFFICIENCY. THE CORRECT RUNNING IN METHOD FOR A NEW MACHINE IS: FIRST, PERFORM AN IDLE RUNNING IN OF THE ENGINE AND THE ENTIRE MACHINE, RUNNING THEM AT LOW SPEED, MEDIUM SPEED, AND HIGH SPEED RESPECTIVELY FOR ABOUT 5 HOURS; THE SECOND STEP IS TO BREAK IN WITH 50% LOAD, USUALLY BY FINDING RELATIVELY SOFT SOIL FOR ROTARY TILLAGE OPERATION, WHICH TAKES ABOUT 15 HOURS; STEP THREE, CHANGE THE ENGINE OIL. AFTER COMPLETING THE ABOVE TWO STEPS, DRAIN THE ENGINE OIL WHILE IT IS HOT AND REFILL IT WITH AN APPROPRIATE AMOUNT OF NEW OIL THAT MEETS THE BRAND. STEP FOUR, CHECK AND ADJUST THE VALVE CLEARANCE AND THE WORKING STROKE OF OTHER CONTROL MECHANISMS, TIGHTEN LOOSE SCREWS, ETC. ENGINES THAT HAVE BEEN REPLACED WITH CRANK CONNECTING ROD MECHANISM COMPONENTS (SUCH AS CRANKSHAFTS, CONNECTING RODS, SMALL BUSHINGS, PISTONS, PISTON RINGS, ETC.) MUST ALSO BE RUN IN BEFORE THEY CAN BE PUT INTO NORMAL USE.3、 ALWAYS MAINTAIN THE THREE 'CLEANLINESS'（1） CLEANING OF FUEL: IN TONGJIANG COUNTY, IT IS NECESSARY TO USE STANDARD NO. 0 DIESEL, PREFERABLY USING A RELATIVELY LARGE IRON DRUM TO BUY FUEL FROM A REGULAR GAS STATION, SETTLING FOR 48 HOURS BEFORE USE. IT IS RECOMMENDED TO CLEAN THE FUEL TANK ONCE A MONTH AND REPLACE THE FUEL FILTER EVERY SIX MONTHS (OR AFTER 500 HOURS OF USE);（2） CLEANING OF LUBRICATING OIL: DIESEL ENGINES AND GEARBOXES BOTH USE DIESEL ENGINE OIL WITH A CC RATING OR HIGHER. THE ENGINE OIL MUST BE IN BARRELS, AND THE FIRST OIL CHANGE SHOULD BE DONE AFTER 20 HOURS OF RUNNING IN. AFTER THAT, THE OIL SHOULD BE CHANGED EVERY 100 HOURS OF OPERATION. BEFORE STARTING EACH TIME, CHECK WHETHER THE OIL LEVEL IS SUFFICIENT. IF IT IS NOT ENOUGH, MAKE UP FOR IT, AND IF IT IS TOO MUCH, DRAIN SOME (OTHERWISE THE ENGINE WILL OVERHEAT AND EMIT BLUE SMOKE). AFTER EVERY 100 HOURS OF OPERATION, CLEAN THE OIL FILTER. IT IS STRICTLY PROHIBITED TO USE GEAR OIL IN THE GEARBOX. THE OIL INSIDE SHOULD BE CHANGED AFTER 8 HOURS OF HALF LOAD OPERATION, 20 HOURS OF FULL LOAD OPERATION, AND EVERY 150 HOURS OF OPERATION THEREAFTER;（3） CLEANING OF COMBUSTION AIR: FREQUENTLY CHECK AND CLEAN THE FUEL FILTER, KEEP A PROPER AMOUNT OF OIL IN THE OIL BOX OF THE AIR FILTER, AND REPLACE THE OIL BOX AND FOAM WITH NEW PARTS AS SOON AS POSSIBLE AFTER THEY ARE DAMAGED, OTHERWISE THE VALVE, PISTON, PISTON RING AND CYLINDER WILL BE QUICKLY WORN OUT OVER A LONG PERIOD OF TIME.4、 BE CALM AND COMPOSED IN DEALING WITH FOUR TYPES OF UNEXPECTED SITUATIONS(1) CARELESSNESS DURING FIELD TRANSFER MAY CAUSE THE MICRO TILLER TO OVERTURN. IN SUCH A SITUATION, THE MACHINE SHOULD BE STOPPED IMMEDIATELY. IF THE ENGINE CANNOT BE STOPPED DUE TO DAMAGE TO THE CONTROL MECHANISM, THE PRESSURE RELIEF LEVER CAN BE PRESSED IMMEDIATELY TO STOP THE MACHINE (THIS METHOD IS ONLY ALLOWED TO BE USED IN EMERGENCY SITUATIONS SUCH AS ENGINE FAILURE OR DIESEL ENGINE RUNAWAY);(2) WHEN USING THE NEW MACHINE TO MANUALLY PLOW PADDY FIELDS IN REVERSE GEAR, IT IS EASY TO OPERATE IMPROPERLY, CAUSING THE MICRO TILLER TO PLANT WATER (I.E. THE MACHINE HEAD TOUCHES THE GROUND, AND THE MUD AND WATER ARE SUCKED INTO THE CYLINDER THROUGH THE AIR FILTER). AT THIS TIME, THE MACHINE SHOULD BE STOPPED IMMEDIATELY FOR INSPECTION AND CANNOT BE USED AGAIN (OTHERWISE IT IS HIGHLY LIKELY TO CAUSE SERIOUS DAMAGE TO THE ENGINE), AND CONTACT A WARRANTY REPAIR POINT AS SOON AS POSSIBLE;(3) WHEN THERE IS ABNORMAL NOISE INSIDE THE MACHINE, IT SHOULD BE STOPPED IMMEDIATELY FOR INSPECTION, AND THE FAULT PHENOMENON SHOULD BE REPORTED TO THE THREE GUARANTEE MAINTENANCE POINT; (4) WHEN THERE IS A MINOR MALFUNCTION IN THE MACHINE, IT SHOULD BE DEALT WITH AS SOON AS POSSIBLE, OTHERWISE 'IF A MINOR ILLNESS IS NOT TREATED, IT WILL EVENTUALLY BECOME A BIG PROBLEM'. ATTENTION: WHEN CLEANING WEEDS OR DEALING WITH OTHER MINOR MALFUNCTIONS ON ROTARY TILLAGE TOOLS, BE SURE TO STOP THE MACHINE BEFORE PROCEEDING; WHEN THE TEMPERATURE IS LOW IN WINTER AND IT IS DIFFICULT TO START A DIESEL ENGINE, IT IS RECOMMENDED TO REPLACE THE ENGINE OIL WITH A VISCOSITY LOWER THAN THE SPECIFIED GRADE. IT IS STRICTLY PROHIBITED TO START THE ENGINE BY USING THE INTAKE IGNITION METHOD.5、 TO GRASP THE CORRECT PARKING METHOD FOR MICRO TILLAGE MACHINES DURING THE IDLE PERIOD OF AGRICULTUREMICRO TILLAGE MACHINES HAVE STRONG SEASONAL USAGE, AND ARE OFTEN PARKED FOR MORE THAN SIX MONTHS DURING IDLE PERIODS. IMPROPER PARKING METHODS CAN ALSO CAUSE DAMAGE (SUCH AS RUSTING OF VALVES AND CYLINDER LINERS DUE TO POOR VALVE SEALING). AFTER THE LAST USE OF THE MICRO TILLER THAT NEEDS TO BE PARKED FOR A LONG TIME, THE OLD ENGINE OIL IN THE DIESEL ENGINE SHOULD BE DRAINED WHILE IT IS STILL HOT, AND NEW ENGINE OIL SHOULD BE INJECTED. REMOVE THE OIL FILLER PLUG ON THE CYLINDER HEAD COVER, ADD ABOUT 2 MILLILITERS OF ENGINE OIL, PRESS THE PRESSURE RELIEF STARTING HANDLE WITHOUT RELEASING IT, PULL THE RECOIL STARTING ROPE 5-6 TIMES (USUALLY NOT NECESSARY TO START THE DIESEL ENGINE), THEN RELEASE THE PRESSURE RELIEF HANDLE AND SLOWLY PULL THE STARTING ROPE UNTIL YOU FEEL A LARGE RESISTANCE. DRAIN THE DIESEL ENGINE FUEL TANK (LEAVING A SMALL AMOUNT). NEXT, RELEASE THE ENGINE OIL FROM THE GEARBOX, INJECT NEW ENGINE OIL, AND FINALLY REMOVE THE ENGINE OIL, SOIL, WEEDS, ETC. FROM THE MICRO TILLER AND CUTTING TOOLS. STORE THE MACHINE IN A WELL VENTILATED, DRY, AND SUN AND RAIN PROOF PLACE.
