It is well known that school buses are used to transport students to and from school. The normal maintenance of school bus vehicles is related to the service life of the vehicles and the safety of drivers and passengers. If not properly maintained or used, it will cause vehicle failure and bring safety hazards. Therefore, in addition to attending the repair station on time for mandatory maintenance, daily maintenance work should also be done, which is beneficial to the "health" of the vehicle. Here are some daily maintenance tips.
Park the school bus on a level road. Pull out the ruler to check the amount of oil. If it is within the(F) and(L) marking lines, it is within the normal range if it is lower than(L). The specified type of oil should be added, and the liquid surface after filling must not be higher than(F) bit.
When the engine is in a hot state, do not open the radiator cover, otherwise it may be scalded by splashed coolant or high temperature steam. After the engine cools, the liquid surface of the check coolant should be between the full position and the low position. Otherwise, distilled water or pure water or refrigerant should be added. After adding water, the liquid surface height cannot exceed the full position. If it is found that the coolant decreases rapidly in a short period of time, check for leaks in the cooling system or check at the pit stop.
For most busy school bus drivers, school buses are things that will leave after oil is added. In many cases, the importance of maintenance is ignored. Some people do not even know basic maintenance knowledge. We are introducing kindergarten bus standards, mainly daily maintenance matters, so that we take good care of your car again.
You might think that maintaining the school bus can be done by the garage. These jobs don't have to be done on their own. We're not talking about changing your own oil, changing your own brakes, but about simple, easy and practical items.
We advise drivers to make a habit of checking around the school bus to see if there is enough pressure on the four wheels or if there are obstacles around the bus to block the way. Look around the school bus window whether there is a broken situation after the key, simply check each. Whether the operation of the item is normal, such as light number, horn, brake, etc., this will prevent the operation from being found to be in trouble or even busy.
In addition to this action, there is also a lot of work that can be done by yourself. Develop every week to check each liquid level when the engine is not hot, such as pulling out the oil ruler to see if the indicator is between two scales, brake fluid, tank coolant, battery water, etc., are some of the safety measures you can check yourself. The school bus battery is a link that should be noticed from time to time. The environment-friendly battery without adding water does not need to check the battery water stock, but it must pay attention to the status of the battery surface to show the window. In general, green represents normal, transparent, and no color means that it must be charged as soon as possible. In black, most of them can't start the engine.
In fact, a school bus battery has a normal life of about two years. If a new battery is replaced, but the power is rapidly weakening, it may represent a problem with the generator. When replacing batteries, technicians usually write down the installation date with a pen. This is a good reminder of when to replace the new battery.
Reserve tires are often overlooked. It is not unknown that the reserve tires stored under the trunk of the car will definitely leak. Therefore, the pressure of the spare tires should be checked from time to time. When pumping the tire gas at the fuel station, it is advisable to use more. One or two minutes, Open the back of the kindergarten school bus to pump up the spare tires. The number of pounds should be about two pounds more than the tires on the four streets.
The reserve tire that installs the school bus also has its own door. First, it uses the tool to loosen the screw a little, and then it raises the car with a beak, and then immediately pushes the rear spare tire into the bottom of the car to prevent sudden failure. At least there is a reserve tire when the car falls down. support, Then loosen all the screws. There is also a certain order for the replacement screw to be removed. Starting from the bottom, the diagonal type is loosened. The installation starts from the highest one. The same is true for the competition, and then the car is put back on the ground to allow the four wheels to stick to the ground. Finally, force the screw to tighten.
When the pressure of the school bus tire is checked, it must be performed at a low temperature. If the tire is walking for a period of time, the temperature of the tire will increase due to rolling, and the pressure value is inaccurate. To know whether the tire is leaking, in addition to the naked eye, the fetal gas meter can be used to measure it accurately. The fetal gas figures can be found in the owner's manual of the school bus or the stickers attached to the car. Most of the stickers are attached to the cylinder cover or to the driver's door.
Pay attention to the replacement of water dials
If you find that the kindergarten school bus is not moving smoothly, hear or feel the water scratching sound, it must be replaced as soon as possible. Most of the water dials for kindergarten models can be purchased at car boutiques or even oil stations. The packaging boxes will list the joint car, or the length of the existing water dials can be measured with a ruler, which can be matched by size. The replacement method is also very simple, as long as you pull out the old water before carefully looking at the correct location of the installation, you can easily put on. The vast majority of school bus manufacturers around the world use the same type of water to dial, so there is little chance of problems.
These daily school bus maintenance methods of school buses are simple but practical, and they are very helpful for the safe use of school buses.
