1. Park the engine on relatively level ground overnight before changing the oil. Start changing the oil the next morning. Do not start the engine before changing the oil. This will help drain the used oil more completely. .
2. Remove the engine oil pan screws and use a bucket to catch the used oil. Remove the oil filter while changing the oil. After disassembly, use a paper towel to wipe off the old oil stuck on it, and then directly install the new one. Do not use too much force to avoid tight cracks.
3. Use the new filter for one day after installation. After high temperature, the filter will become more tight. When you find that no old oil is flowing out of the oil drain hole, you can add new oil.
4. When adding new oil, check the oil dipstick while adding to avoid adding too much oil. WhenIf you see that the engine oil has reached the upper end of the oil dipstick mark, you can start the engine. .
Remember not to press the accelerator first, wait a minute at low speed, then turn off the engine. Check the engine oil after 30 seconds. At that time, the engine oil will usually be a little less than before. , because some of the engine oil has been filtered by the new engine oil inside, then add a little more until the oil reaches the upper end of the mark on the dipstick oil.
Typically, there will be a board on the excavator cab window or door. This table shows the engine oil fill quantity for this model. Fill in the oil according to this quantity.
In addition, there is an oil dipstick on the excavator engine. When adding oil, add as little as possible. After adding a little oil, wait about a minute and removeCheck the oil dipstick to see if. The current oil level is on the oil dipstick scale. Between lines, adding several times can avoid adding too much oil. It is normal for the oil level to be between the upper and lower scale lines of the oil dipstick.
5. After changing the engine oil, remember to check the disassembled parts for oil leaks. Clean the engine with a little water. Do not direct water towards the generator and motor to avoid short circuits.
Detailed informationExcessive engine oil will reduce engine power. When the engine is running, the crankshaft handle and the big end will move quickly. If there is too much oil, the crankshaft handle and connecting rod will be violently agitated. When the crankshaft and connecting rod stir the engine oil, a certain amount of energy is consumed, which invisibly reduces the power output of the engine and increasese fuel consumption.
Excessive engine oil can easily damage the oil seal and cause oil leakage. When there is too much oil, the oil pressure in the engine will increase, which will have a significant impact on the oil seal, shorten the life of the oil seal and cause oil leakage. engine oil.
Engine oil is the “blood” of the engine. In addition to protecting the engine and extending its life, it can also reduce the risk of engine failure and reduce fuel costs. Of course, if used incorrectly, it will also cause the excavator to fail, leading to increased fuel consumption and shortened service life.
The dangers of not changing engine oil on time
1. The acid resistance of engine oil and its ability to neutralize acidic substances deteriorate with long-term use, causing the engine to malfunction.become acidic during operation. The value increases significantly, causing acid corrosion of the engine and shortening the life of the engine.
2. The viscosity-temperature characteristics of engine oil used for a long time change.Bad. At high and low temperatures, viscosity changes significantly. Poor starting ability at low temperatures will prevent oil from quickly reaching the spaces between moving parts when the engine is started, resulting in dry friction between parts and increased wear. Likewise, a good lubricating oil film cannot form at high temperatures and cannot provide good protection to the engine.
3. The cleanliness, dispersion and oxidation resistance of engine oil used for a long time are very poor. During operation, the engine is likely to produce a large amount of carbon deposits, colloids,e sludge and other substances. deposited in the engine, which can lead to poor lubrication, increased component wear, increased fuel consumption, reduced power and, even in severe cases, oil passages can become blocked, causing pulls on the cylinders and other consequences.
In summary, engine oil should be replaced after a certain period of use, and the replaced used oil should not be thrown away or thrown away at will. It must be handed over to a competent recycling company. for environmental protection and reuse.
You are asking about the dangers of entering the paint shop from an automobile generator factory. to have.
Because the main components of paint are: resin, solvent, pigments and fillers. The resin is basically non-toxic. The solvent will cause damage to the respiratory tract.res and to human skin and will affect the skin. blood system. Pigments and fillers are mainly powdered or flaked solids used for coloring, some are toxic and others less toxic, mainly causing damage to the respiratory system.
Be prepared when spraying: gas mask (do not use a regular mask), one-piece paint suit, work shoes, preferably earplugs (general spraying will make a lot of noise) eat more than usual. Once animal blood, drink more water and fruit, one or two years is a long time.
