(1) If the engine is strictly accelerated, there will be a certain amount of lubricating oil in the bearing, which can be lubricated when the engine and idle are allowed, but when the engine speed exceeds 1000r / min, it is necessary to have a lubricating oil flow. Lubrication, at least 15 to 305 after the engine is started to form a hydraulic and oil flow in the lubrication system. If the throttle is started, the maximum speed can be reached in 2S, which means that the bearing will be in ten seconds. In the lubrication state, and operate at a higher speed, it is easy to cause bearing damage. To this end, you should remember that you must start when the throttle is in an idle position, that is, at least in the 30s engine speed does not allow more than 1000R / min. If the engine is placed for more than two days, in order to provide lubrication to the boot, the engine (cut fuel) can be switched until the oil pressure display can be started.
(2) Try to avoid working under low speed overloading under low speed overloading, the bearings are in the boundary lubrication state, especially when the engine speed is reduced to the vibrating point, due to the active metal of the vibration wave Direct contact between direct contact is very large. To this end, low speed overload conditions should be limited to minimal.
(3) Regularly check the lubricant, if necessary, add or replace the mechanical use process, it should be added to the oil surface height of the oil undercar, and it should be added to the time of being added; and the quality of the lubricant should be checked regularly, if necessary, replace it.
Check the quality of the lubricant, you can observe the lubricating oil on the elongated oil by experience, which is a rough judgment, ie, the quality of the lubricant is measured at the same time, to determine if the lubricant needs to be replaced.
Method for replacing the lubricant: Generally, the waste oil is released after the engine is turned off, then adding new lubricants, preferably combining the oil-filled cleaning system, so that the added new lubricant is not contaminated.
