4 hp power digging machine parameters 1) Engine Engine: 1E50F-1, two-stroke 2) Displacement Displacement: 71CC 3) Maximum Power Max Power: 4.8HP / 3.2KW 4) Carburetor Carburetor: Float type diaphragm type) engine GW / NW Engine GW / NW: 13.4 / 11.4KGS drill Gross Weight Drill GW / NW: 17.5 / 15.0KGS (100mm / 200mm / 300mm) digging machine is widely used in slope, sand, hard land of nursery stock digging planting landscaping projects, from the periphery to dig unearthed trees; fence buried pile digging; fruit trees, forest fertilization digging, digging diameter:, 200-400mm. , Land drilling operations per hour of not less than 80 pits, working eight hours a day by calculating, you can dig 640 pits, is 30 times more artificial. The real process of automatic operation, drill so that people freed from the heavy manual labor. Power powerful, beautiful appearance, comfortable operation, low labor intensity, all-terrain, high efficiency, easy to carry and field field operations. ? Use and maintenance of common sense: ??? First, a general security measures to prohibit the use indoors; 2, keep a safe distance from flammable materials and not less than 1m; 3, refueling, no smoking, must stop the engine, gasoline is prohibited overflow; 4, when the work should be equipped with protective goggles and protective equipment, no protective cover Do not use; 6, hands and feet away from the machine before turning and stopping. Second, check the operation before a fuel tank external surface self check the fuel surface, if the fuel surface is low, add oil to the upper limit. Fuel unleaded gasoline and two-stroke oil is 25-30: 1 mix ratio of preparation, never use pure gasoline and gasoline containing impurities; 2, check the air filter element air filter dirt, dirt found should be cleaned; 3, check the throttle cable at the throttle cable free play ends, and check the oil doorknob smooth operation; 4, check the blade blade mounting nut is loose, tighten the nut if necessary; check the blade for cracks, nicks, bending and wear, if necessary, replace; 5, cutterhead guard checks cover is loose, if necessary, tighten security guard bolts; check for damage shield, if necessary, be replaced; three, maintenance 1, spark plug demolition spark plugs, clean up carbon measurement (electrode) gap between 0.6-0.7mm; 2, overhaul the fuel filter and cleaning the fuel tank of the engine fuel poured out, remove the filter and gently clean; remove attached to the fuel box moisture and dirt; 3, heat sink is dirty through the hood to check the heat sink, if you want to clean up dirty; 4, check the fuel pipe fuel pipe, if aging or spills must be promptly replaced; 5, the timely replacement blades ? Fourth, save fuel poured out of the fuel tank, according to injection pump several times, and then empty the fuel tank of fuel, the blade cover is mounted to the blade, clean the mower into place. This machine can be a longer service life of mechanical maintenance of common sense:? ??? 1, two-stroke gasoline engine oil (90 #), oil sae30. The new machine idle running-two hours, the heat engine after changing the oil before normal use. In normal use the accumulated work 30 hours or so to replace a oil. Before and after each use, check the oil level. ? ???? 2, when the two-stroke air-cooled gasoline engines for work, crankcase temperature should not exceed 90 degrees, 15-20 minutes after the shutdown can continue to work when overheated. Adding fuel to be carried out in a cold machine. Do not use full throttle for a long time when not mowing. ? ???? 3, gasoline prohibit speeding and should be shut down at low speeds. ? ???? 4, use the correct type of oil, are plant products, cleaning, gasoline must be clean, fresh. ? ???? 5, non-professionals can not adjust the carburetor. ? ???? 6, the air filter should always check regularly replaced. Dirty filter with soap and water after use to dry. ? ???? 7, 100-300 hours of operation of the gasoline engine, it should be clear coke once. Remove the cylinder head when clear, clear cylinder, cylinder head, pistons, valves and other attachment coke. Coke not enter the cylinder bore and valve seats. ? ???? 8, holding cylinder gasoline engine in particular fins cleaning. ? ???? 9, refueling, inspection, maintenance, warranty when to disconnect the spark plug cap, do not smoke, stay away from open flame. ? ???? 10, not in the operating room. In addition to the operator, the unrelated persons above 15 meters away from the machine when the machine is working. ? ???? 11, before and after each use, check the machine working part and other parts of the tightness of the bolts. ? ???? 12 with the clutch, clutch exposed before that the machine is not installed, the gasoline engine may not start. ? ???? 13 other lubricating parts of the machine, follow the instructions on a regular basis to be filled with oil or grease as needed.
