1. Replace diesel engine lubricating oil
1, lubricating oil replacement conditions. If the indoor temperature is lower than 0 ° C, the viscosity of the lubricating oil suitable for other seasons will increase, which is not conducive to the lubrication of the internal parts of the machine, affecting the start of the engine, and the need to replace the low-viscosity lubricating oil.
2, low viscosity lubricating oil model selection. Generally choose the CF-4-15W-40 model lubrication sold by gas stations to meet the needs of diesel engine lubricating oil in winter.
3, how to change the lubricating oil
(1) Use a flat plate to put the diesel engine oil drain port, use a wrench to disassemble the screw rod, and slowly release the oil.
(2) By checking the lubricating oil dipstick, confirm whether the lubricating oil is put clean, in each inspection, need to wipe the dipstick clean, easy to observe.
(3) Tighten the screw rod of the oil discharge port, and slowly inject the low viscosity lubricating oil (Kunlun CF-4-15W-40) into the lubricating oil tank with a funnel. At the same time, it is necessary to observe whether the lubricating oil dipstick scale meets the requirements, and the lubricating oil can be injected into the middle scale. The replaced lubricating oil should be loaded into the barrel, if the original lubricating oil is dirty, no longer continue to use, but it is strictly prohibited to enter the waste lubricating oil at will into the ground.以上翻译结果来自有道神经网络翻译（YNMT）· 通用场景
Two, diesel engine water
Check the water float of the water tank to ensure that the water tank is clean. The diesel generator set used in the gas station adopts the principle of water circulation for body system cooling. In order to prevent the diesel engine body from being damaged by the freezing of seasonal water or ice blocking the channel in winter, causing the diesel engine body to be scrapped or cylinder expansion and other faults, the gas station needs to discharge the diesel engine circulating water and keep no water in the body under the shutdown state.
Note: The diesel generator can not discharge water too early before extinguishing, should run at idle speed, until the cooling water degree drops below 60℃, and then turn off the water when the water is not hot. If the water is released too early, it will be suddenly attacked by cold air when the temperature is high, which will produce sudden shrinkage, easily leading to cracks in the body. When releasing water, the water stored in the body should be completely discharged to prevent it from freezing and expanding, causing the body to burst.
Three, the maintenance of fire caps.
Due to dry winter weather, in order to prevent diesel engine smoke from igniting flammable or combustible materials around, the fire cap switch should be checked to keep the fire cap in daily closed state.
4. Electrical use.
The output power of the diesel generator set is generally about 10KWA, taking into account the impact of the performance of the generator set, power generation instability, when using the generator set, only the production and zero-pipe system computer electricity, do not open the use of gas station air conditioning and water pumps and other high-power electrical equipment, to avoid the burning of equipment or damage to the generator set due to excessive load.
