在灰塵積到1/2”[12.7毫米]之前，從濾清器上卸下機油盤。倒掉機油并在清潔的溶劑或燃油中清洗。
Unload machine oil plate from filter before dust reaches 1/2”[12.7mm] .Pour the machine oil and clean it in clean impregnant or fuel.
注：在潮濕氣候的冬季，更換機油與灰塵較多的氣候下?lián)Q油是同等重要的，因為空氣濾清器的進口位于空氣流中，它將把濕氣帶入濾清器中。
Notice:In moist winter,replacing machine oil is as important as replacing oil when there is too much dust.Because air filter's intake is in air current,it will bring moisture into filter.
用清潔新鮮的、與使用在發(fā)動機曲軸面圓點所示的位置處，并把油盤裝到濾清器上。在很冷的氣候下，有必要使用較輕級的機油。一種帶無泡沫清凈劑或無泡沫添加劑的純礦物油，可以使用在油浴式空氣濾清器中。
Install oil plate back to filter. Under very cold climate,it is necessary to use light level machine oil.A non-foam detergent or a non- foam additive pure mineral oil can be used in bath-type air filter.
注意：決不可使用臟的或用過的機油
Notice:Dirty or used machine oil is not allowed to use.
放出儲氣筒的積水
Let air reservoir's water out
在寒冷的氣候下，儲氣筒和管路中的冷凝水蒸氣可能凍結(jié)而使控制機構(gòu)失靈。
In cold climate, air reservoir and pipeline's condensation vapor will freezes and control syatem will be out of work.
放出儲氣筒中的積水以保持壓縮空氣系統(tǒng)中無水。
Let air reservoir's water out to maintain there is no water in compressed air system.
從燃油箱中放出沉積物
Let fuel tank's deposit
松開燃油箱放油開關(guān)或螺塞（如果有的話），放出約一杯的燃油以清除油中的水分和沉積物。關(guān)閉放油開關(guān)或螺塞。
Loosen fuel tank switch or thread plug(if it is used) ,let a cup of fuel out to eliminate water and deposite.Close switch or thread plug.
燃油/冷卻水過濾分離器
Fuel/cooling water filtration segregator
在檢查燃油箱時，如發(fā)現(xiàn)油箱中的水較通常為多，安裝一個水分離器將是合適的。
It is necessary to install an filtration segregator if there is too much water in oil tank.
請與最近的康明斯經(jīng)銷商接洽，以取得符合要求的弗里特伽德（Fleetguard）油水分離器。
If you want to get qualified Fleetguard fuel/cooling water filtration segregator,Please contact the nearest Cummins agent.
放油塞位于一些燃油濾清器殼和燃油箱的底部，未滿油的油箱中生成的冷凝水多于滿油箱中的冷凝水。所以，油箱應(yīng)盡可能保持接近于加滿狀態(tài)。從噴油咀中流回的溫暖的燃油將加熱燃油箱的燃油。如果在寒冷氣候下油箱油面低，油箱的上部不能被流回的溫暖燃油所加熱，從而增加了水蒸氣的冷凝傾向。在暖和的氣候條下，燃油箱和燃箱都是暖的。但是在夜間，冷空氣使油箱溫度下降的速度遠快于燃油溫度下降的速度。這再一次增加了水蒸汽的冷凝傾向。
Oil drain plug is at the bottom of fuel filter and fuel tank.It will produce more condensation water if oil tank is not full.Therefore,oil tank should be full of oil.The warm oil which returns from nozzle will heat up oil tank's fuel.If oil level in oil tank is too low in cold climate,oil tank's top can not be heated by warm fuel,it will increase the tendency of water vapor condensation.In warm climate,both fuel tank and fuel are warm.But at nignt,the tank temperature dropped faster than the speed of fuel temperature's decline.This will increase the tendency of water vapor condensation once again.
三、“B”級保養(yǎng)檢查
三 “B”level maintenance check
在每作一次“B”級保養(yǎng)檢查時，要完成全部的“A”級保養(yǎng)檢查項目，還要加上下列項目：

Notice:All lubricating oil should be up to standard which stipulated in 1 part list.It is necessary to install original Cummins filter.
潤滑油更換周期
Lubricating oil replacement cycle
1、機油更換周期是用 “圖表法”來決定。此法是要據(jù)燃油消耗量和潤滑
添加量來決定更換周期。
1 Machine oil replacement cycle is decided by “graphology”,it is according to fuel consumption and lubricating oil.
2、 “圖表法”上的時間周期為250小時或6個月。
2 Time cycle om “graphology” is 250 hours or 6 monthes.
3、決定機油更換周期的另一個方法是通過采用機油分析來確定。
3 The other way that can decide machine oil replacement cycle is machine oil analysis
機油分析
Machine oil analysis
決定何時更換機油的另一個方法是通過實驗室試驗進行機油分析。如果濾清器、機油品種或等級更換了，應(yīng)進行一系列新的試驗。
The other way that can decide machine oil replacement cycle is machine oil analysis.If filter machine oil's variety or grade has been changed,A series of new experiment should be done.
開始時，每消耗100加侖燃料（已消耗400加侖后）或每工作20小時（已工作100小時后）要做一次潤滑油分析，直到分析表明需要進行第一次更換機油。
At beginning, every 100 gallons(400 gallons has already been consumed) fuel has been consumed or every 20 hours (100 hours late) it works,It is necessary to carry out lubricating oil analysis one time,until result shoes it is necessary to replace machine oil.

大批貯存補充用的冷卻液
Large quantities of coolant's storing
大批貯存補充用的冷卻液應(yīng)按下列程序混合和貯藏。
Large quantities of coolant should be stored according to the following procedure.
1、 放盡貯存罐中的液體并加以清洗，以除去任何雜質(zhì)。
1 Let storage tank's liquid out and clean the tank,remove all impurity.
按貯存罐的裝載容積計算水和防凍劑（如果需要使用的話）的數(shù)量。例如一個500加侖的貯存罐若按50：50的比例配制冷卻液時需要250加侖的水和250加侖的防凍劑。
Calculate the quantity of water and antifreeze(if it is used)according to storage tank's volume.For example,a 500-gallon storage tank can store 250 gallons of water and 250 gallons of antifreeze according to 50:50 proportion.
3、將貯存罐的總?cè)萘浚觼鰯?shù)）乘以需要的DCA濃度。在上例中，對50：50的冷卻液，每加侖要1.5盎司[每升要12毫升]的DCA。1.5盎司/加侖乘以500加侖[1892升]得到的DCA的總需要量是750盎司（46磅14盎司）[21.3公斤]。
3 The storage tank's total capacity(gallons) multiplies by the required concentration of DCA.For example,50:50 coolant,Each gallon requires 1.5 ounces [each liter requiers 12 milliliters] DCA. 1.5 ounces/gallon multiplies by 500 gallons[1892 liters] DCA,it will be 750 ounces (46 pounds 14 ounces)[21.3 KG]
4、先將水加到貯藏罐中，在連續(xù)攪動中每次加少量的DCA直至全部溶解。水溫應(yīng)超過50℉[10℃]。
4 Add water into storage tank,agitate water until DCA absolutely dissolves.Water's temperature should exceed 50℉[10℃].
5、如要用防凍劑，就在最后加，繼續(xù)攪動以保持配制好的冷卻液在溶液狀態(tài)。若不攪動或循環(huán)。DCA和防凍劑都會沉積在罐底。循環(huán)的辦法是用一個小泵不斷地從罐底吸出DCA和防凍劑再從上面注入液體?？梢苑謩e從冷卻液的液面、中部罐底取樣，分析防凍劑和（或）DCA的濃度，以檢查攪動是否夠均勻。
5 If antifreeze is used,add it finally,agitate it to maintain coolant is in state of solution.If you do not agitate,DCA and antifreeze will deposit in storage tank's bottom.Use a small pump to aspirate DCAand antifreeze from storage tank's bottom,and pour liquid into storage tank from above.
更換DCA水濾清器

一、 季節(jié)性保養(yǎng)檢查
五 Seasonal maintenance check
清洗冷卻系統(tǒng)（秋季）
Clean cooling system(Autumn)
冷卻系必須清潔以使其工作正常。系統(tǒng)中的水垢降低了它從水套吸收的熱量和向散熱器排出的熱量，使用的清潔水以避免堵塞散熱器和缸體中幾百條細(xì)小的水道。對于被水垢和沉積物堵塞了的散熱器芯、加熱器芯、機油冷卻器和氣缸體中的水道，用化學(xué)清洗劑清洗、中和沖洗。
Clean cooling system regularly,System's water scale reduced the quantity of heat absorbed from water jacket and discharged from radiator.The water used to clean system must be clean ,or it will block the cooling system.As for radiator element 、heater element、 machine oil cooler and aqueduct which are blocked by water scale,Clean them in chemical cleaning solvent.
化學(xué)清洗
Chemical cleaning
如果鐵銹和水垢多了，就應(yīng)對系統(tǒng)進行化學(xué)清洗。使用一種好的冷卻清洗劑，如硫酸氫或草酸，然后是中和劑和沖冼。
If there is too much rust and water scale,it is necessary to carry out chemical cleanling to system.You had better use good cooling clean solvent,such as hydrogen sulfate or oxalic acid,and later neutralizer should be used.
壓力沖洗
Pressure cleaning
在加入防凍劑之前先要沖洗散熱器和氣缸體，或在用過的或大修過的發(fā)動機上加裝水過濾器。壓力沖洗散熱器時，打開上下軟管接頭并擰緊散熱器蓋。在上下水管接頭上使用軟管接頭可以方便工作。將槍噴咀連到下水管讓水充滿散熱器。然后逐步加大氣壓以免脹裂散熱器芯子。停止進氣，讓散熱器重新注滿水，然后又加氣壓，如此反復(fù)進行，直到從散熱器出來的水變清為止。
It is necessary to clean radiator and cylinder body before adding antifreeze,and it is also necessary to install water filter on used or repaired engine.In pressure cleaning,open the upper and lower hose coupler and tighten radiator cap.Hose coupler make it more convenient to work.Connect gun nozzle with lower host coupler to add water into radiator.Increase air pressure step by step or radiator element will be damaged.Stop adding air,add water into radiator again,and increase pressure again,back and forth,until water from radiator is clean.
注意：在開始使水流出時不要使用過大的氣壓，以免脹裂散熱器芯子。
Notice:If presuure is too large when water starts flowing out ,or radiator element will be damaged.
沉積物和臟物，除了積沉在散熱器芯子中外，也沉積在氣缸體的槽、坑中。卸下節(jié)溫器，用水沖洗氣缸體。將下面出水口關(guān)小直到氣缸體中流滿了水，施加空氣壓力迫使水從下面出水口流出。如此反復(fù)進行，直到流出的水變清為止。
Deposit and dirty may be in radiator element,in addition to cylinder's groove、 hole.Dismantle thermostat,clean cylinder with water.Turn down lower water outlet untill cylinder is full of water,increase air pressure to force water flow out through lower water outlet,back and forth, again and again,until water from cylinder body is clean.
更換水管（需要時）
Replace water pipe(if necessary)
檢查機油濾清器和冷卻系統(tǒng)的軟管和軟管接頭，看有無滲漏及損壞。損壞了的軟管的碎片進入冷卻系統(tǒng)或潤滑系統(tǒng)會限制甚至堵塞散熱器芯子的細(xì)小水道和機油冷卻器，部分地停止循環(huán)，所以需要時更換之。
Check machine oil filter and cooling system's tube and hose coupler to see whether they are damaged. Tube's chips may enter cooling system or lubricating system ,even block radiator element's water channel and machine oil system.So if it is damaged,replace it as soon as possible.
