  (5) often maintain the normal operating temperature of the engine, too high oil dilution, lubrication conditions deteriorate; Too low will produce acid corrosion, causing pitting spalling. General appropriate working temperature is 70-80 ℃, evaporative engine may be slightly higher.
  (6) should be paid attention to when starting the engine lubrication, because after the engine flameout, lubricating oil is the most flow into the oil pan, each pair of surface under dry friction and the half dry friction, if starting immediately, must increase cylinder wear parts, such as speed, therefore when starting rocking-turn crankshaft several circles, first make motion pair surface provided with certain lubrication.
  (7) preheat the engine for a period of time after starting, because the engine temperature is low at this time, the cylinder and other parts have not been fully lubricated, otherwise accelerate the wear of cylinder liner, piston, piston ring, journal and bearing bush. When the engine temperature of 40 ℃, 60 ℃ was put into operation.
  (8) long time overload is prohibited.
  (9) forbid the engine to run rapidly for a long time. Because the engine is running rapidly for a long time, the nozzle is not atomized well, the fuel and air are not mixed evenly, the combustion is not complete, the cylinder is easy to produce carbon, aggravating the cylinder wear. In addition, the long idle running also accelerated wear. Zhejiang ruiqing auto parts co. LTD
  (10) start the machine correctly and try to reduce the starting times. If the machine stops for less than 15 minutes, do not turn off the engine to reduce the starting times. When starting the engine, do not put the throttle to the maximum position to forcibly start, otherwise the diesel injection into the cylinder is too much, resulting in starting, even if it can start, because the cylinder fuel is too much, incomplete combustion, resulting in increased wear and tear. In general, when the temperature below 15 ℃, starting start don't go door, idling crankshaft several laps, feel at ease and then add the starting small throttle.
