1. Before starting the tractor, inject 75~85°C hot water into the water tank to warm up the body and prohibit starting with an open fired roasting car or dry water without cooling water. This not only exacerbates the wear of the locomotive, but also prone to accidents such as fuel tank explosion and body cracking. When the engine is not warmed up and the hot water is not being filled, preheating and starting with the starter are prohibited.
2. When the tractor stops working in a short time, it should be noted that the temperature of the cooling water must not be lower than 40°C, otherwise the engine should be operated at a low speed.
3. After each class of tractor work, park it in a flat place until the water temperature drops to 50 ~ 60 °C, open the water tank drain valve, put the water into the bucket, and continue to use it after heating the next day. When cranking, the crankshaft should be cranked so that the water in the pump housing can be drained. The water must not be released from the net to prevent freezing of the drain valve.
4. Before adding the antifreeze, the scale of the cooling system must be removed; the added amount of cooling water should not be too full, and various antifreezes cannot be mixed; antifreezes do not leak when used, because some antifreezes are flammable and some antifreezes are toxic. Therefore, operators should pay attention to safety.
