发动机冷却系统的保养
Clean regularly during using process
发动机用冷却液可以是煮沸的自来水，也可以是防冻液。防冻液的有效期为
2
年或
1600h
，超过此期
限应更换并冲洗冷却系统，然后再加入新的防冻液。
Engine Cooling System Maintenance Cooling fluid of engine could either be the tap water or antifreeze. The
valid date for antifreeze is 2 years or 1600h, replacing and cleaning the cooling system if excess the date, then
fill with fresh antifreeze
冷却系统水垢的清洗：在保养前一班，以每
10L
水中加
750g
苛性钠和
150g
煤油的比例的溶液加满冷

10h
～
12h(
注意：冬季必须保温以防冻结
)
，然
后重新启动发动机以中速运转
20min
后，停机放出清洗液。
Cooling fluid of engine could either be the tap water or antifreeze. The valid date for antifreeze is 2 years or
h, replacing and cleaning the cooling system if excess the date, then fill with fresh antifreeze.
Cooling system scale cleaning: before maintaining, add 750g caustic soda and 150g kerosene in every 10L
water then fill them into the cooling system. Running the engine in medium speed for(5-10)min, keep
for(10-12)h(reserve the heat and avoid freeze in winter),then start up the engine in the medium speed for
20min, then stop and drain the cleaning fluid.
待发动机冷却后把水管插入水箱进行冲洗，这时应将水箱底部的放水阀打开。清洗后关上放水阀，并
加水让发动机运转数分钟后再把水放尽。待发动机冷却后，再按规定添加新的防冻液或冷却水。
After the enging cooled down, unbolt the water release valve at the bottom of water tank. Clean the water
tank with the water pipe, check the water tank buffer regularly, jf it got aging replace a new water tank for
fear of shorten using life. Turn off the water releasing valve, running the engine for several minutes. After the
engine cool down, add new antifreeze or cooling water.
重要事项：
Important notes
在冬季，应根据气温条件经常检查防冻液的浓度，如不合适就要立即恢复正常浓度。对于未使用防冻
液的拖拉机待水温下降至
70
℃以下时，在发动机怠速运转情况下应把水放尽，以免冷却水结冰将机体
冻裂。
In winter, in accordance with the temperature, check the thickness of antifreeze , if out of place, recover the
normal thickness. As to tractor with no antifreeze, when temperature fall below 70
℃
, drain the water during
用气压表检查轮胎压力，轮胎充气压力见拖拉机技术规格。轮胎压力过高或过低都将缩短轮胎寿
命，并对拖拉机的行驶操纵产生不良影响。
Check tire pressure with a barometer. Common tire inflation pressure refers to Technical Specifications of
tractors. Too high or too low tire pressure will shorten the tire life and have negative impacts on traffic control
of tractors.
将拖拉机停放在水平地面上，发动机熄火，卸掉燃油箱下面的放油螺塞，放出油箱底部的沉积物。油箱
具有贮存油料、沉淀水分和杂质的作用，使用中应定期进行清洗，清除污物。
Parking the tractor in flat ground, extinguishing engine, take off the drain plug on the fuel tank drain the used
oil in the bottom Oil tank functions reserve oil, subside wet and impurity.
